4400M Digital RO System
1.0 GENERAL INFORMATION
The 4400M - Digital Reverse Osmosis (RO) system produces up to 16.7 US gallons per minute
(64.4 litres per minute) of product water suitable for applications requiring biological and inorganic purity. The product water quality meets ISO 13959, ISO 11663 and ISO 26722
Standard requirements. More than 99% of all microorganisms, pyrogens, particulates, organics with a molecular weight greater than 300, and up to 95% of all dissolved inorganic contaminants from the feed water are removed.
The 4400M RO system is supplied on a skid consisting of a pump, RO element housings, manifolds, valves, pressure gauges, flow rotameters, a control panel and tubing. The system
skid and manifolds are shipped fully assembled, pre-piped and pre-wired. See APPENDIX A1 for
detailed description of the system components. The standard RO system is available in 208VAC
(60 Hz) 3-phase but it is also customized to 230, 380, 420, 460, 575 VAC 3-phase or 115/230
VAC single phase power supply. The system is offered with a choice of 2, 3, 4, 5, 6, 8, 9, 10 or 12
RO membrane elements to suit specific product flow requirements.
A NEMA 4-12 control panel consists of a digital controller, an electronic digital interface and display for setting and monitoring process control parameters. Optional control interfaces are provided with the RO system for:
Feeding product water to a Storage Tank or a Direct Feed line.
Diverting product water to the drain.
A Remote Alarm Panel.
A Remote PC Interface.
A Product 0.1 Cell Constant Conductivity/Temperature Sensor.
NOTE The 4400M system does not include external pre-treatment and posttreatment devices, piping and fittings to the point of use.
1.1
HOW DOES THE RO PROCESS WORK?
Reverse Osmosis (RO) is a cross flow membrane filtration process used for water purification. It removes both dissolved organics and salts using a mechanism different from ion exchange or activated carbon. The pressurized feed water flows across a membrane, with a portion of the feed permeating the membrane. The balance of the feed sweeps parallel to the surface of the membrane to exit the system without being filtered. The filtered stream is called the
“permeate”. The second stream is called the “concentrate” because it carries off the concentrated contaminants rejected by the membrane. Because the feed and concentrate flow parallel to the membrane instead of perpendicular to it, the process is called “cross flow
filtration”. Depending on the size of the pores engineered into the membrane, cross flow filters are effective in the classes of separation known as reverse osmosis, nano-filtration, ultra-
filtration and the more recent micro filtration.
MAN-4400MCOLD (rev.J) page 11 of 103
4400M Digital RO System
The cross flow membrane filtration allows continuous removal of contaminants, which in the normal flow filtration would “blind” and plug the membrane pores very rapidly. Thus the cross
flow mode of operation is essential to the RO process.
The RO was the first cross flow membrane separation process to be widely used. The RO removes most organic compounds and up to 99% of all ions. A selection of RO membranes is available to address varying water conditions and requirements.
The RO can meet most water standards with a single-pass system and the highest standards with a double-pass system. This process achieves rejections of 99.9+% of viruses, bacteria and pyrogens. Pressure in the range of 50 to 1000 psig is the driving force of the RO purification process. It is much more energy-efficient compared to phase change processes such as distillation and more efficient than the strong chemicals required for ion exchange regeneration.
1.2
RO TECHNOLOGY USED IN MEDICAL APPLICATIONS
The performance requirements of the RO system used by medical and pharmaceutical businesses are different from many market segments because, in addition to conductivity and total organic carbon (TOC), viable microbial organisms and endotoxin are also measured in the
RO product water. Specific microbial limits are defined in the ISO 13959, ISO 11663 and ISO
26722 standards. From a regulatory perspective, the end-user’s obligation is to ensure these limits are satisfied at the point of distribution. Advancements in membrane technology combined with pressure from regulatory agencies have increased RO system performance expectations, particularly regarding microbial organisms and endotoxin measurements. Today, it is common for end-user protocols to stipulate very low, viable microbial organisms and endotoxin levels in RO product water.
The RO membranes have a relatively large surface area, ambient operating temperatures, and the absence of chlorine or other disinfectants that combine to create a microbial organisms breeding environment on the product side of RO membranes. To exhibit better system control over microbial levels, routine chemical sanitizing processes are employed based on the bacterial level measured in the product water.
Chemicals used in the RO membrane cleaning procedures include low and high pH-based cleaners for the primary purpose of removing hardness scale and organic deposits that may build up on the membrane surface as foulants.
Bacteria counts taken from water streams are typically representative of the planktonic organisms in the stream and not necessarily of microbial organisms that exist in a biofilm within the water system. Biofilms are a complex organization of microbial organisms formed by one of many common species, which adhere to a surface and cover themselves from the fluid stream in a somewhat protective polysaccharide boundary layer.
MAN-4400MCOLD (rev.J) page 12 of 103
4400M Digital RO System
Biofilms form naturally, but the growth may be mitigated with appropriate fluid velocity, smooth sanitary pipe designs and periodic and appropriate sanitization processes. However, biofilms have proven to be quite resilient to many chemical sanitization processes due to their protective boundary layer. Studies demonstrate biofilms may survive even after 60 minutes of exposure to chlorine-based sanitizing chemicals. Therefore, preventing the formation of biofilms is a primary goal with respect to regular and periodic sanitization processes.

4400M Digital RO System
3.0 OPERATIONS AND MONITORING
3.1
SYSTEM OPERATIONS
The main operations performed by the 4400M - Digital RO system are as follows (See FIGURE
3.1 - Operations Flow Chart):
Normal RO - There are four modes of normal RO operations:
Stop – In this mode, the RO system will stop operating.
Standby – In this mode, the RO system remains on but does not perform any operation except system flush at auto scheduled frequency for the set duration. Refer to section
3.2.2 for changing the flush duration time and frequency.
Run – In this mode, the system will perform normal RO operations. Refer to the SETUP
menu in section 3.2.2 for different options.
Flush – In this mode, the system continuously flushes the product water to drain. This will help reduce membrane fouling by allowing more water to pass over the membrane surface.
Sanitization - The 4400M – Digital RO system can be sanitized using a chemical disinfectant.
Chemical Sanitization/Cleaning – This operation is performed in the MANUAL mode using a Clean-In-Place (CIP) system or a tank. For sanitization/cleaning with the tank, an option of using the RO pump is provided.
NOTE The RO system controller is locked-out by the 4400HX Hot Water Sanitization
System controller during part of the hot water sanitization of the distribution loop.

SYSTEM OPERATION CONTROLS
The 4400M – Digital RO system is equipped with the user-friendly DO841.4 monitoring controller with V6.7e.132 software. The controller uses a keypad interface and display to provide useful information on the system. Parameters can be easily changed to suit the user’s needs. Optional output cards can provide information via a remote display or with a Personal
Computer (PC). The PC will provide the information in a Windows format. The system has many unique features including programmable automatic restart for low pressure conditions, programmable alarm setpoints for product quality, feed temperature, programmable poor quality shutdown delay and programmable flush times and durations. The controller has nonvolatile memory backup for power failure conditions. If a power failure should occur once the power has been restored the system would re-start in the same mode it was in before the failure occurred.
In this section, an overview of the operation of the digital controller is provided to help the user
gain familiarity and program basic system parameters. Refer to APPENDIX A1 for a description
of system components, APPENDIX
A2 for a pictorial view of the System Control Panel and

4400M Digital RO System
3.3.1 System Start-up
For Initial start-up or to restart from a complete system shut-down, refer to the start-up
3.3.2 Normal Operations
See section 3.2 to perform RO operations and set-up system parameters.
3.3.3 System Shut-down
For temporary stoppage, the RO system can be shut-down in following ways:
By pressing the STOP key on the display keypad located on the control panel.
By turning the Main Disconnect lever to the OFF position when access to the control panel is required for repair.
For extended shut-down period, follow the procedures below:
NOTE Due to site conditions some of the procedures might have to be altered.
1. At shut down, flush the system with product water. The flush water must be free of any chemical additives.
2. Relieve the system pressure and shut down the feed pump.
3. When the system is secured, ensure that the water does not drain from the elements. Also ensure that there is no back pressure on the elements from the permeate side.
NOTE If there is greater than atmospheric pressure on the permeate line during operation, check valves should be included in the permeate line to prevent even momentary back pressure on the membrane elements during a shutdown.
4. For extended shut-down, greater than one week, a preservative solution must be added to the
system to eliminate biological growth. Refer to section 4.4.6
5. If the plant is to be secured for less than one week, it is usually sufficient to flush the system with fresh, pretreated feed water once per day to minimize biological growth.
CAUTION In an event of complete system stoppage, restart the system as per Start-up
instructions provided in section 2.5 to avoid possible damage to the system.

MONITORING SYSTEM PERFORMANCE
The 4400M system is designed to monitor the system performance. The following parameters are monitored and displayed by the system:
Active operation mode status (Running, Flushing, Stopped, Tank Full, Tank Filling)
Pump running time in hours (ROP), up to 32000 hours
Time remaining before next flush cycle in minutes and seconds
Time remaining when in auto flush condition
Product tank level: Low, Intermediate, High
Water Quality and Temperature Monitoring:
Feed water conductivity or resistivity
Feed water temperature
Product water conductivity or resistivity
Product water temperature
% Rejection of water impurities between input and output conductivities
Product water non-temperature compensated conductivity or resistivity using the 0.1 cell constant optional probe. This probe is factory set.
Any issues encountered by the system relating to water quality, pressure and temperature are flagged by the system controls and alarms are displayed.
Alarm/Warning Monitoring:
Poor product water quality
Low feed water pressure (for less than 12.5 psi, fixed digital input)
Pump input current overload (digital input)
High feed water temperature
Remote standby
Optional audible alarm (Re-alarm every 2 minutes if alarm is still present)
Log all the alarms in the Sample Log Sheet provided in APPENDIX
technician in troubleshooting.
NOTE The troubleshooting of the system shall be performed by trained personnel or a Mar Cor Technician.
The common problems encountered by a RO system are due to either mechanical failure of the pressurization system or failure of the RO membrane. The breakdown of the pressurization system can result from:
MAN-4400MCOLD (rev.J) page 35 of 103
4400M Digital RO System
Electrical problems
Mechanical interruption of the water flow
Mechanical destruction of the pump
The other common problems are related to the failure of RO membranes. They are caused by:
Inadequate RO pre-treatment that causes the membrane to foul, scale or become chemically altered
The introduction of chemicals that are incompatible with the RO membrane
Breakdown of the membrane or mechanical seals (O-rings) between the different elements
Therefore, in addition to monitoring the RO system parameters, the RO membrane performance must also be monitored. Percent Rejection is used by the 4400M system to test the performance of the RO membranes. Percent Rejection measures the product TDS (Total
Dissolved Solid) against the feed TDS. This percentage gives a general idea of the efficiency of the RO membrane to remove ions. Because the ion exclusion rate of a membrane is a function of the feed water ion concentration, it is very important to monitor changes within the feed water to better control its impact on the final product water.
NOTE The product water quality is proportionally related to feed water quality. The user is responsible for monitoring the feed water quality.
Significant deterioration in feed water quality may change the product water quality beyond acceptable limit. (Reference: ISO 26722. Element 6.3, Item j).
A table in APPENDIX A9 lists critical system parameters that must be checked at specified
frequency to ensure that any seasonal or temporary change in the feed water quality meets the system specifications.

NOTES:
(1) The Actual membrane maximum temperature is 45
C (113 o
F). The System alarm setpoint is 35
C (95 o
F).
(2) The Maximum pressure drop includes piping and is shown per membrane.
3.5.1 Effects of Pressure on Membrane Performance
The operating pressure of a system also affects the product flow rate. The amount of product water produced is directly proportional to the pressure difference between the feed and product sides of the RO membrane. This pressure difference is known as the Trans-Membrane
Pressure (TMP) and can be calculated as:
TMP = Feed Pressure - Product Pressure
MAN-4400MCOLD (rev.J) page 37 of 103
4400M Digital RO System
If the product from the RO system feeds directly to a distribution loop or downstream equipment such as Electrical Deionization or Ion Exchange Polishing, there may be significant product pressure that decreases the TMP. The product flow rate given for each system is based on the TMP. It may be necessary to increase the feed pressure to get sufficient TMP if the product pressure exceeds 15 psi (1 bar).
NOTE
NOTE
Never exceed a Trans-Membrane Pressure of 220 psi (15 bar) for TFC cartridges.
Trans-Membrane Pressure should be reduced if the feed water temperature is greater than 25 o C (77 o F) to avoid exceeding the design flow rate.
3.5.2 Effects of Recovery on Membrane Performance
The recovery of RO systems is defined as the percent of feed water (including reject recycle water) that becomes purified product water. The recovery is calculated by:
% Array Recovery =
Product
Product + Reject + Reject Recycle
X 100
% System Recovery =
Product
Product + Reject
X 100
The design recoveries of the RO systems are given in the table below. The percent salt rejection and rate of membrane fouling can be affected by the array recovery and system recovery. At higher recoveries, the reject flow rate through the system is reduced. This results in an increase in the concentration of dissolved solids at the membrane surface, and a decrease in the ability of the reject stream to flush suspended materials from the system.
Recycle Flow =

Recoveries are listed above without recirculation. With the optional recirculation valve closed, exceeding these recoveries will result in short membrane life. This will void the RO membrane warranty.
After setting the proper recovery, as suggested above, the recirculation valve can be opened to increase the system recovery up to 75% provided the feed water, sampled at reject, is still within specification.
The reject and reject recycle flow control valves are used to adjust the flow rates and recovery on the system. Periodic flow adjustment will be required as the membrane cartridges age and as the feed water condition changes.
NOTE
NOTE
NOTE
Do not exceed the design recovery as this can result in decreased salt rejection and membrane fouling or scaling.
Never completely close the reject and reject recycle valve.
When either opening or closing any needle valve, DO NOT over-extend or over-tighten the valve as galling damage may occur. When fully opening the valve, do so till resistance is felt and then close the valve ¼ turn. When fully closing the valve, DO NOT use wrenches or other tightening tools. Close valve till snug
3.5.3 Effects of Temperature on Membrane Performance
The product flow rate for the RO system given is based on a feed water temperature of 25°C
(77 o F). The product flow rate will be reduced at temperatures below 25°C as the viscosity of the water increases, making it more difficult to force water through the membrane.
NOTE At temperatures higher than 25°C, the operating pressure should be reduced to maintain the design flow rate. Operating at a higher product flow will void the RO membrane warranty.
If the temperature is not 25° C, a correction factor must be used to calculate the expected product flow rate from the system. The table below provides temperature correction factors to apply for feed temperatures other than 25°C.

4.3
OVERVIEW OF SYSTEM SANITIZATION & RO MEMBRANE CLEANING
The disinfection of the 4400M – Digital RO system must be done to control bacterial growth and to remove biological film. Based on the feed water source, system operating conditions and the user’s preventative maintenance practices, a routine sanitization treatment is recommended on the RO system.
Chemical cleanings are performed to remove particulate, inorganic scale and organic fouling from the RO membranes. There is no specific frequency for cleaning of the RO system. A cleaning should be performed when the flow rates or water quality begin to drop below
allowable limits (refer to tables in section 3.5 and Appendix A8 ).
CAUTION When performing a sanitization using the MINNCARE
®
disinfectant (or any approved chemical disinfectant containing hydrogen-peroxide), an acid cleaning must be performed on the RO system first to remove any metal build-up on the membranes, preventing oxidization. When cleaning a RO system follow membrane manufacturer’s recommendations and/or customer approved cleaning/sanitization procedures.
It is recommended that the RO system is disinfected using MINNCARE ® monthly or as required.
In order to understand the concept of RO membrane cleaning, it is important to know something about membrane fouling. The next sub-sections present basic information about the different types of foulants and how to identify them when they affect RO membrane performance.
There are three major groups of RO membrane foulants: hardness/metal oxides, colloids/silica, and aluminum/polymers. These potential foulants can exist independently, but can also occur together resulting in a "mixed" fouling.
The symptoms of RO membrane fouling can range from gradual decline in product water flux over several months, to severe loss overnight. The ultimate results of membrane fouling can vary from complete recovery after cleaning to permanent damage.
The correct cleaning method is essential to a successful cleaning. The cleaning instructions on the following pages will allow selection of the appropriate cleaner based on the types of RO pre-treatment being employed and feed water characteristics. While the occasional need for cleaning may arise due to pre-treatment equipment failure or a temporary change in feed
MAN-4400MCOLD (rev.J) page 45 of 103
4400M Digital RO System water composition, persistent or severe fouling should be a cause for re-evaluation of the RO pre-treatments.
The following basic discussions are of RO foulants, how to identify them, and what to do once they have affected membrane performance:
4.3.1 Dealing with a Hardness/Metal Oxide Fouling Problem
What are Hardness and Metal Oxides?
Hardness most commonly encountered is in the form of calcium carbonate (CaCO
3
) or calcium sulfate (CaSO
4
).These compounds are found widely throughout the United States and Canada and occur naturally in groundwater. Metal oxides are the result of soluble substances naturally occurring in groundwater being oxidized prior to, or at the membrane surface. Iron and manganese are examples of commonly found metals that can pose significant fouling problems to an RO element.
The Problem
Membranes become scaled, a term used in cases of hardness fouling, when the hardness minerals become supersaturated and they precipitate out of solution onto the membrane surface. This is caused by pure water being removed from the feed solution at the membrane surface resulting in an increase of the concentration of mineral salts left behind. When the solubility limits are exceeded, precipitation occurs. The severity of the problem is related to hardness levels, pH, water temperature and recovery efficiency of the RO system. The same type of fouling problem can occur with several types of soluble metals that are forced out of the solution and become deposited on the membrane surface.
Recognizing Hardness Scaling/Metal Oxide Fouling
In general, simple hardness scaling results in a slow decline of flux and the attendant decrease in salt rejection. The decline can take from weeks to months to become apparent. If a combination of scaling and metal oxide fouling occurs, there will be a rapid decrease in flux and salt rejection.
What to do if Hardness/Metal Oxide Fouling is suspected?
Check to see if the softener is working properly.
Find out the levels of hardness and metals in the feed water.
Clean the RO system before there is a 15-20% decline in flux from normal readings.
Failure to reverse this type of scaling will result in permanent damage to the membranes.
Generally, the use of chemical solution is recommended. Refer to the manufacturer’s
recommended chemicals in section 4.4.2.
MAN-4400MCOLD (rev.J) page 46 of 103
4400M Digital RO System
4.3.2 Dealing with a Colloids/Silica Fouling Problem
What are Colloids? What is Silica?
Colloids are very fine, suspended solids that can clot and become entrapped on the RO membrane surface. Colloids found in feed water are usually of the aluminum silicate group.
Colloidal materials including aluminum hydroxide can also be found. Silica that is dissolved
(SiO
2
) is naturally present in most feed waters. It is usually found in concentrations ranging from 1-100 mg/L.
The Problem
During the RO process, colloids are destabilized and as the concentration of salts increases, they clot and foul the element. The rate of fouling is directly related to the concentration of colloidal material present, and its stability. A test called the SDI (Silt Density Index) is usually used as a measure of colloidal concentration. The stability of colloids in solution is a function of their electrical charge. This stability is often expressed as a measurement of zeta potential.
Silica poses a problem when, due to the removal of pure water in the RO process, it becomes more concentrated and polymerized to form colloidal silica, or precipitate as a silicate.
Recognizing Mixed Colloids/Silica Fouling
Fouling due to colloids/silica material is usually quite slow. Its symptoms are a gradual decline in flux and no real change in salt rejection. In the presence of metal oxides, however, the decline can be more dramatic. If fouling is not treated, an eventual decrease in salt rejection will be observed.
What to do if Colloidal/Silica Fouling is suspected?
Find out from your water department if the presence of colloids/silica material is temporary or a standard constituent of your feed water.
Pre-treatment may be required for these foulants. Check to see if the pre-filter is of the right type and working properly. An "absolute" rated filter may be required.
Consider the addition of an appropriate chemical feed sanitization system.
Refer to the cleaning instructions in section 4.4.4 or 4.4.5.
4.3.3 Dealing with an Aluminum/Polymer Fouling Problem
What are Aluminum and Polymers?
Aluminum and polymers are frequently used by municipal water treatment facilities as flocculent to settle out dirt and other suspended matter in water sources. Ideally, all of the added aluminum/polymer is supposed to be removed in the process, but in actual practice, a small amount of aluminum/polymer often remains in the water supply. One of the properties of these flocculent that makes them effective is that they easily knot and come out of solution.
MAN-4400MCOLD (rev.J) page 47 of 103
4400M Digital RO System
Unfortunately, this property can present troublesome conditions for high efficiency RO systems, with over 33% recovery.
The Problem
When residual aluminum/polymers are present in the feed water supply to a RO system, a membrane fouling problem may exist. Aluminum/polymers can clot on the membrane surface and slowly clog it, especially in the presence of other constituents such as silica and iron.
Unfortunately, water softeners and filters are not effective at removing aluminum/polymers.
The extent of the fouling problem is also related to the pH of the feed water and the recovery efficiency of the RO system. The lower the pH and the lower the recovery, the less aluminum/polymer complexes will tend to foul the membrane.
Recognizing Aluminum/Polymer Fouling
The first sign of aluminum/polymer fouling is a loss of product water flow rate. Unlike most other types of fouling which takes a long time to develop, aluminum/polymer fouling can cause a reduction in product water flow rate in a matter of days. There may be little or no decrease in percent rejection performance. The sooner the signs of aluminum/polymer fouling are recognized, the easier it will be to reverse its effects. Therefore, it is important to check the product water flow rate on a frequent basis.
NOTE There are other causes for lowered product flow rates such as colder feed water temperature. This should be ruled out as a possible cause before aluminum/polymer fouling is suspected.
What to do if Aluminum/Polymer Fouling is suspected?
Inquire with the municipal water department and find out if aluminum/polymers are used in their treatment.
Find out the levels of silica and iron, including those imparted by galvanized piping, are present in the feed water.
If the product flow rate decreases from its expected level, clean the membranes as per
instructions in section 4.4.4 or 4.4.5.
If the water conditions are such that aluminum/polymer fouling continues to occur, then periodic cleaning may have to become part of regular maintenance.
Consider additional methods such as adding a chemical feed sanitization system or lowering the recovery to deal with the fouling.

CHEMICAL CLEANING AND SANITIZATION
This section describes requirements and procedures for the cleaning of the RO membranes and chemical sanitization of the 4400M – Digital RO system. Information on the selection of the right chemicals and their correct use is provided.
MAN-4400MCOLD (rev.J) page 48 of 103
4400M Digital RO System
4.4.1 Clean-In-Place (CIP) Equipment Requirements
The Clean-In-Place (CIP) system configuration can be used for the RO system sanitization or membrane cleaning. It must be designed to support the flow and pressure requirements of each individual system. The general guidelines for construction of a CIP system are provided below.
Maximum Cleaning Feed Flow Rate and Pressure
Element Nominal Diameter:
4”
Maximum Flow Rate:
10.0 gpm per housing
Maximum Pressure:
60 psig
NOTE Clean pressure vessels only in parallel. Where a series array of pressure vessels is used for higher recoveries, each pass must be cleaned separately.
Cleaning Tank
The cleaning tank should be sized 2-3 times the estimated holding volume of the RO system including membranes, CIP interconnect hoses and piping. It must be large enough to prevent cavitation of the pump. The tank material must be biocompatible with the chemicals used in the sanitization process. Refer to the tables below in order to determine the estimated holding volume of hoses and membranes.

The cleaning pump must be sized to provide the maximum flow required per element. For example a system with 4” membranes and a configuration of 3 banks of 4 elements will require a pump to deliver 30 gpm. The pump’s wetted components should be constructed from 304 or
316 stainless steel.
MAN-4400MCOLD (rev.J) page 49 of 103
4400M Digital RO System
NOTE The pump must be flushed with clean water after a sanitization is completed to prevent corrosion and damage to the pump.
Filter Housing (Optional)
The filter should be sized for the maximum flow rate. It should be constructed from 316
Stainless Steel, Polyethylene or Polypropylene.
Filter Cartridges (Optional)
An optional 5.0 micron nominally rated filter cartridge should be installed in the filter housing to trap any particulate that is removed during the cleaning/sanitization process.
Controls
Controls should include the following:
NEMA 4-12 enclosure
Panel disconnect
Pump motor starter
Pump hand/off/auto switch
Low tank level switch
Piping and Valve Configuration
The piping and valves should be sized for the maximum flow rate. The material must be able to withstand cleaning/sanitization solutions. Refer to the sample flow drawing in FIGURE 4.2 for a typical CIP system set-up.

Because of the individuality of the RO water system in design and construction as well as the quality of raw feed water, all RO water does not contain the same components. Dependent upon your particular system, all or portions of the following procedure may be for sanitizing.
MAN-4400MCOLD (rev.J) page 56 of 103
4400M Digital RO System
Biological or organic fouling of the membrane or other parts of the system should be removed with appropriate cleaner. It is important to follow the membrane manufacturer’s recommended cleaning procedure. After cleaning, flush the system with RO permeate. Mineral deposits should be removed with an acidic cleaner prior to sanitizing of the membrane. Again, follow the membrane manufacturer’s recommended cleaning procedure. Then flush the unit with RO permeate. The presence of iron or other transition metals, in conjunction with the hydrogen peroxide in MINNCARE ® Liquid Disinfectant, could cause membrane degradation.
Prepare a 1% solution (1 part MINNCARE ® Liquid Disinfectant to 99 parts water) by adding the
MINNCARE ® Liquid Disinfection solution to permeate water. Fill the entire water circuit to be sanitized with a 1% solution and allow the diluted solution to reach a minimum temperature of
20 o C (68 o F). Do not exceed the membrane manufacturer’s recommended temperature.
Recirculate the 1% MINNCARE ® Liquid Disinfectant until the entire system is filled. Allow the elements to soak in the 1% MINNCARE ® Liquid Disinfection solution for a minimum of 36 minutes at 20 o C (68 o F).
Rinse the RO system and check for residuals by following the directions on the MINNCARE
®
Residual Test Strips label. The residual test strip should indicate less than 2ppm. Rinse times will vary depending on the size of the RO system. Residual sanitizer that may enter the system because of chemical rebound can be eliminated by diverting product water to drain for a short period of time.
4.4.4 Cleaning/Sanitization Procedure Using a CIP System Skid
The procedure below will assist an operator in cleaning the RO membranes or sanitizing the RO system using a Clean-In-Place (CIP) system. This procedure is written for the CIP configuration shown in Figure 4.2.
CAUTION When performing a cleaning/sanitization it is very important to use the proper safety apparatus. Refer to the Material Safety Data Sheet (MSDS) provided with the sanitant or cleaner before using it. Carefully follow the manufacturer’s safety instructions on the labels affixed to the chemical containers.
CAUTION When performing a sanitization, an acid cleaning must be performed first. This will remove any metal build-up on the membranes and prevent the membranes from oxidization. When cleaning the system, ensure it is operating at high flow rates and low pressure. If high pressure is used, contaminants can be pushed further inside the membranes.
NOTE Due to varying site conditions, some of these procedures might have to be altered.

4.4.5 Cleaning/Sanitization Procedure Using a Tank and RO Pump
This procedure will assist an operator in cleaning the RO membranes or sanitizing the RO system using a small tank and the RO pump only.
CAUTION When performing a cleaning/sanitization it is very important to use the proper safety apparatus. Refer to the Material Safety Data Sheet (MSDS) provided with the sanitant or cleaner before using it. Carefully follow the manufacturer’s safety instructions on the labels affixed to the chemical containers.
CAUTION When performing a sanitization, an acid cleaning must be performed first. This will remove any metal build-up on the membranes and prevent the membranes from oxidization. When cleaning the system, ensure it is operating at high flow rates and low pressure. If high pressure is used, contaminants can be pushed further inside the membranes.
CAUTION This procedure should only be used when the RO pump is less than 5.0 horse power (hp). Damage to system and pump can occur. System with greater than
5.0 hp RO pump should use only a separate cleaning pump (Clean-In-Place
System) when a cleaning or sanitization is required.
NOTE Due to different site conditions, some of these procedures might have to be altered.
1. Record the flow rates, pressures and product quality before cleaning/sanitization. This data will be compared with data collected after cleaning/sanitization to determine if the cleaning/sanitization improved the RO performance.
2. Place the RO system in the STOP mode.
3. Close the inlet valve to the RO pre-filter housing.
4. Relieve the system pressure.
5. Connect a flexible hose (1” or 1 ½”) from the bottom of the tank to the RO skid CIP inlet valve.
Secure the line. See schematic in APPENDIX A1 for valve location.
6. Connect a flexible hose (½”, ¾”, or 1”) from the RO reject CIP outlet valve to the return connection on the top of the tank. Secure the line.
7. Connect a flexible hose (½”, ¾”, or 1”) from the RO product CIP outlet valve to the return connection on the top of the tank. Secure the line.
8. Close the RO product to process and RO reject to drain valves.
9. Fully open the RO product CIP and the RO reject CIP valves.
10. Fully open the reject and the reject recycle needle valves.
NOTE When either opening or closing any needle valve, DO NOT over-extend or over-tighten the valve as galling damage may occur. When fully opening the valve, do so till resistance is felt and then close the valve ¼ turn. When fully closing the valve, DO NOT use wrenches or other tightening tools. Close valve till snug.

4.4.9 MINNCARE
®
Test Strips Overview
The MINNCARE
®
test strips provide quick results with easy-to-read indicators. Use the
MINNCARE
®
1% TS test strips as a pass/fail measurement for adequate concentration of sterilant after dilution. Then, verify residual levels after rinse-out using the MINNCARE
®
Residual
Test Strips.
They verify adequate concentration of a 1% MINNCARE solution during sanitization of your high purity water system. These convenient dip-and-read strips can be used at any test port in your system to provide an accurate pass/fail measurement of MINNCARE solution. The test strips are easy-to-use and are conveniently packaged in 100 test strips per container. Each strip has a
“reaction zone” pad located at one end of the strip. When stored and used properly, the test strip pad can indicate residual MINNCARE levels as low as 1 part per million (ppm). The reaction zones are set to provide six different reading levels at 100, 30, 10, 3, 1 and 0 (zero) parts per million.
CAUTION: Store sealed vials in a cool dry environment. It is not necessary to refrigerate.
Once open store at room temperature. DO NOT REFRIGERATE. Failure to store tests property will result in inaccurate readings. Close vial tightly when not in use.
NOTE: Each container has an expiry date. Do not use after date printed on the container.

RO MEMBRANE ELEMENT STORAGE
The general storage procedures are described below for short-term and long-term storage.
CAUTION Under no circumstances shall the system be exposed to a temperature less than 0°C (32°F). Irreversible damage to the membranes, system components and piping can occur.
NOTE The composite polyamide type of RO membrane elements must not be exposed to chlorinated water under any circumstances. Any such exposure will cause irreparable damage to the membrane. Absolute care must be taken following any disinfection of piping or equipment or the preparation of cleaning or storage solutions to ensure that no trace of chlorine is present in feed water to the RO membrane elements. If there is any doubt about the presence of chlorine, perform a chemical testing to confirm. Neutralize any chlorine residual with a sodium bisulfite solution, and ensure adequate contact time to accomplish complete dechlorination.
MAN-4400MCOLD (rev.J) page 65 of 103
4400M Digital RO System
Short Term Storage
Short-term storage is for periods of more than five days and fewer than thirty days when a RO system must remain out of operation with the RO elements in place. For short-term storage of the membrane element, prepare each RO train as follows:
Flush the RO section with feed water while simultaneously venting any gas from the system.
When the pressure tubes are filled, close the appropriate valves to prevent air from entering the system.
Reflush at five-day intervals.
Long Term Storage
Long-term storage is for a period of more than thirty days when a RO system must remain out of operation with the RO elements in place. For long-term storage, prepare each RO train as follows:
Clean the RO membrane elements in place.
Flush the RO section with an approved biocide or an approved available product prepared from product water.
When the RO section is filled with this solution, ensure it is completely filled and close the valves to retain the solution in the RO section.
Repeat the last two steps with fresh solution every thirty days if the temperature is below 27°C (80°F) or every fifteen days if the temperature is above 27°C (80°F).
When the RO system is ready to be returned to service, flush the system for approximately one hour using low-pressure feed water with the product to drain valve open and then flush it again at high pressure for 5 to 10 minutes with the product to drain valve open. Before returning the
RO system to service, check for any residual biocide in the product.
Replacement Membrane Storage
When RO elements are stored prior to installation, they should be protected from direct sunlight and stored in a cool, dry place with an ambient temperature range of 20°C to 35°C
(68°F to 95°F). During the period of transit between the factory and the plant site, the elements should not be exposed to temperatures below freezing, 0°C (32°F) or above 45°C (113°F). New
Elements are enclosed in a sealed polyethylene bag containing a storage solution, and then packaged in a cardboard box.

4400M Digital RO System
DESCRIPTION & FUNCTION OF SYSTEM COMPONENTS
Pre-Filter Cartridge
A pre-filter housing is installed on the feed inlet of the system and is located on the front of the system skid. The housing contains a 1.0 micron filter cartridge or 25/1 dual grade cartridge on larger system (6-12 membranes). As the feed raw water flows through the filter, the suspended particles that are greater than the micron rating of the filter are trapped. The filter used is a graded density type. The outer core of the filter has a larger pore size and they progressively get smaller towards the middle of the filter. The rating, in micron size, is measured at the core of the filter. This type of filter will help prevent premature plugging.
Pressure Gauges
Four pressure gauges are installed at various points in the RO system. They are as follows:
Two 0-100 psig gauges are installed on the inlet and outlet of the pre-filter housing. They provide indication of the feed water pressure and also provide indication of the pressure differential (delta) at the pre-filter. This delta pressure reading helps the operator to determine when the filter is required to be changed.
One 0-400 psig gauge is installed on the pump discharge. The gauge provides a reading of the pump discharge pressure before entering the first membrane housing.
The final 0-400 psig gauge is installed on the reject manifold. It provides a reading of pressure after the water has gone through all the membrane housings. With this and the pump discharge gauge the delta pressure can be calculated. This reading will provide an indication fouling condition of the membranes.
Solenoid Valves
Two solenoid valves are installed on the system. The position and purpose of each valve is described below:
Feed Inlet Valve
This 1” or 1½” valve is located on the outlet of the pre-filter housing. It is a normally closed valve that isolates the pretreated feed water. It will open when the system is in normal operation.
Reject Valve
This ⅛”solenoid valve is located on the reject manifold. It is a normally closed valve. The valve will automatically open when the system is in the flush or clean mode. It allows a higher amount of water to be rejected down the drain and increases the cross flow across the membranes to help reduce fouling.
MAN-4400MCOLD (rev.J) page 73 of 103
4400M Digital RO System
Product to Drain Valve (Optional)
This optional ½”, ¾” or 1” valve is located just after the product outlet valve and is plumbed to the drain. It is a normally open valve. The valve will remain open when the water quality is greater than the setpoint and automatically close when the water quality is less than the setpoint during the RUN mode. The valve will remain closed during the STANDBY, FLUSH and
STOP mode and in all alarm conditions.
Feed Water Low Pressure Switch
A normally closed feed water low pressure switch, pre-set to 12.5 psig, senses the feed water pressure. It is located on the bottom left side of the panel. It is connected with a 1/4” tube to the inlet water block just after the feed solenoid valve. When the system is in operation and the feed pressure drops below 12.5 psig, it will shut down the system and alarm after a 10 second delay. This will prevent damage to the booster pump.
CAUTION Feed water pressure must be between 30-60 psig when the system is in operation. Continuous operation of the system below 12.5 psig can result in premature pump and motor failure.
RO Pump
A vertical multi-stage stainless steel centrifugal pump increases the feed water pressure to 150-
300 psig (10.3-20.7 bar) required for purification by the reverse osmosis process. The pump is mounted on the base of the skid frame in the front.
Conductivity/Temperature Sensors
Two conductivity/temperature sensors are installed on the system. They provide readings for the feed water and product water conductivity and temperature. Their location and purpose are as follows:
The feed conductivity/temperature sensor is installed in the feed block. It measures the conductivity/temperature of the feed water mixed with the recycled reject water before the booster pump. The measured conductivity will be higher than the raw feed water source. The feed water temperature is also measured at this point. A setpoint of 35°C
(95°F) will shut the system down after a 10 second delay to prevent damage to the membrane cartridges.
The product conductivity/temperature sensor is installed in the product block. It measures the product conductivity/temperature of the final product water. The system controller calculates the system percent rejection using the feed and product conductivity readings. The percent rejection indicates the amount of impurities that the system is removing from the feed water. It is calculated as follows:
MAN-4400MCOLD (rev.J) page 74 of 103
4400M Digital RO System
% Rejection =
Feed - Product
Feed
X 100
NOTE The percent rejection is calculated based on the conductivity of the feed water after mixing with the recycled reject water.
Manual Flow Control Needle Valves
Three manual needle control valves are installed on the system to provide pressure and flow adjustment of the various streams. Their location and purpose are as follows:
The reject valve is installed on the left branch of the reject manifold. This valve is used to control the reject flow to drain and pressure.
The reject recycle valve is installed on the right branch of the reject manifold. This valve is used to control the recycle flow and pressure.
The final valve is located on the pump discharge line just behind the pump. It controls the pump discharge pressure.
CAUTION Never fully close the reject and reject recycle valves when the system is in operation. Damage to equipment can occur.
NOTE When either opening or closing any needle valve, DO NOT over-extend or over-tighten the valve as galling damage may occur. When fully opening the valve, do so till resistance is felt and then close the valve ¼ turn. When fully closing the valve, DO NOT use wrenches or other tightening tools. Close valve till snug.
CAUTION Proper flows, pressures and recoveries must be maintained at all times.
Failure to operate the system within the design parameters will result in permanent damage to the membrane cartridges.
Flow Rotameters
Three flow rotameters are installed on the system. Their location and purpose are as follows:
The reject rotameter is located just above the reject needle valve. This rotameter shows how much reject water the system is sending to drain.
The reject recycle rotameter is located to the right of the reject rotameter. It provides indication of the amount of reject water that is being recycled back into the feed of the system.
MAN-4400MCOLD (rev.J) page 75 of 103
4400M Digital RO System
The product rotameter is located to the right of the recycle rotameter. It indicates the amount of product water the RO system is producing.
From these flow readings, % Array Recovery and % System Recovery can be calculated. Refer to
section 3.5.2 for the formula.
Manual Valves
Manual valves are used as isolation or sampling valves on the system and their location and purpose are as follows:
A ¼” valve is located on the feed line block. It is used for performing the feed water chemistry test.
A 1” or 1½” valves is located on the feed line to the right side of the skid just before the pump. This is the Clean-In-Place (CIP) inlet connection used for introducing the cleaning/sanitization solution into the system.
Two ½”, ¾” or 1” valves are located on the reject line just above the flow rotameter.
These valves are used to isolate the reject water to drain and divert to the CIP tank when a cleaning/sanitization is required.
Two ½”, ¾” or 1” are located on the product line just above the flow rotameter. These valves are used to isolate the product water to the process and divert to the CIP tank when a cleaning/sanitization is required.
A ¼” valve is located on the product line before the flow rotameter. It is used to collect samples for water analysis.
A ¼” valve is located under the reject pressure gauge. It is used to collect water samples to calculate the LSI index.
CAUTION Always leave one valve open on the product and reject stream. If both valves on either one or both the streams are closed, damage to the system and/or personal injury can occur.
Check valves
One or two check valves are installed on the system. Their location and purpose are as follows:
A ¾” valve is installed on the recycle line just before it ties into the feed water piping.
This check valve will prevent the back-flow of feed water from the pump suction into the reject line.
The optional second check valve (½”, ¾” or 1”) is installed on the outlet of the product to tank solenoid valve. This prevents the back-flow of product water in the RO system.
This valve must be installed in the direct feed application.
Pressure Relief Valve
MAN-4400MCOLD (rev.J) page 76 of 103
4400M Digital RO System
A single or double (on systems with 6 to 12 membranes) pressure relief valve is installed on the product line. It will open if both product and CIP valves are closed; or if the product divert valves fail. This will prevent over pressurizing the product line or membranes.
Control Panel
The control panel is constructed from the following main components:
Electrical enclosure
Main power disconnect
Microprocessor controller
Step down transformers
Keypad interface and display
Pump motor protection devices
Fuses, Terminals
See APPENDIX A2 for a view of switches and indicators located on the 4400M control panel.

A7 REQUIREMENTS FOR INSTALLATION OF EXTERNAL CONNECTIONS TO THE
4400M SYSTEM
DRAIN CONNECTION REQUIREMENTS
Facility must meet the following requirements:
Drains must be sized for the maximum flow of the system.
Drain connections must be plumbed such that siphoning of the system will not occur.
Provide adequate air gaps for each drain connection.
PIPING REQUIREMENTS
Installation piping that is exposed to hot water or is in contact with the product water must meet the following requirements:
Compatible with RO product water.
Stainless steel must be passivated prior to use and/or if welding is used for joining.
Material must meet the current ISO 13959, ISO 11663 and ISO 26722 standards.
Piping must be routed in such a way as to minimize dead legs, at point of use, larger than 3 times the inside diameter of the pipe.
The minimum flow velocity in the piping system is 3 ft/s, for indirect feed systems and
1.5 ft/s for direct feed systems.
PRE-TREATMENT REQUIREMENTS
The 4400 M Digital RO system will operate most efficiently on filtered water with a pH less than negative concentration LSI (Langlier Saturation Index) and a Silt Density Index (SDI) of 3 or below. If the machine is operated on water with higher pHs, other forms of pre-treatment may be necessary. A water analysis prior to start-up of the machine is required. To minimize the chances of calcium carbonate, calcium sulfate, or other mineral precipitation on the membrane, your equipment supplier will evaluate each application and water condition and make specific recommendations to ensure continuity of membrane element warranty. Data from the water analysis is analyzed to determine if potential problems may exist. If the machine is to be run at a different location than was originally intended, a new water analysis is required for warranty consideration and should be sent to your equipment supplier for review and recommendations for operation of the machine.
MAN-4400MCOLD (rev. J) page 83 of 103
4400M Digital RO System
The following pre-treatments are recommended for a typical surface potable drinking water source:
A temperature blending valve for maintaining feed water temperature at 25 C (77 F) for optimum performance.
Two (2) back washable carbon filters for the removal of chloramines. The carbon filters must be sized to meet the minimum empty bed contact time as per ISO 13959, ISO
11663 and ISO 26722 standards.
An automatic water softener for removal of hardness.
Note Water for dialysis must meet the minimum requirements as per ISO 13959, ISO
11663 and ISO 26722 standards.
POST-TREATMENT REQUIREMENTS
To assure the maximum product quality to your process and to protect the system the following recommendation are provided:
Product mechanical safety pressure relief valve (60 psig, 414 kPa setpoint) installed before the product divert valves. This will prevent over pressurization of the product line due to mechanical or operator error (this relief valve is included on all standard
4400M Digital RO Systems).
Automatic product divert valves are installed after the manual product isolation valve.
These valves can operate electrically or pneumatically with an auto/drain switch and light installed in the panel. This will allow the product water to divert to drain when the system is OFF/standby/tank full, flush mode or if the quality is less than 90% rejection.
This will assure the product water sent to the process is within the desired specifications.
Note The above information is for recommendations only. Depending on the process requirement, these requirements might not be needed. Please consult your local water treatment representative.
PANEL ELECTRICAL TERMINATION REQUIREMENTS
Refer to the electrical schematic provided with the system.
FEED WATER REQUIREMENTS
Feed water must meet the most current National Drinking Water Regulations in the USA and
Guidelines for Canadian Drinking Water Quality in Canada for potable water including the following listed in the table below:

PANEL ELECTRICAL FIELD TERMINATION DESCRIPTIONS FOR THE OPTIONAL FEATURES
Alarm Group:
This 24VAC contact can be used to provide a signal to a building control system or a nurse’s station.
When an alarm condition occurs the contact will be active.
CAUTION It is recommended that a 24VAC relay be installed between the contact and the monitoring device to prevent damage to the controller. The contact is rated for a maximum load of 1.0 Amp @ 24VAC when the standard 150VAC step-down transformer is used. If a higher current is required (up to maximum of 5.0 Amps @ 24VAC) the capacity of the step-down transformer should be increased.
Audible Alarm:
This 24VAC contact can be used to activate an audible alarm. When an alarm condition occurs the contact will activate an audible alarm. If the audible alarm is silenced and the alarm condition is still present the audible alarm will re-activate within two minutes.
CAUTION It is recommended that a 24VAC relay be installed between the contact and the monitoring device to prevent damage to the controller. The contact is rated for a maximum load of 1.0 Amp @ 24VAC when the standard 150VAC step-down transformer is used. If a higher current is required (up to maximum of 5.0 Amps @ 24VAC) the capacity of the step-down transformer should be increased.
MAN-4400MCOLD (rev. J) page 98 of 103
4400M Digital RO System
Remote Start/Stop Timer:
This contact is designed to interface with an optional 7-day timer. This allows the user to program a start and stop time when the system is in operation. The contact used to activate this input must be a normally open TYPE-C DRY CONTACT.
CAUTION Contacts must be a TYPE-C DRY CONTACT. Damage to the controller will occur if powered contacts are used.
NOTE Customized menu configuration is required to use this function.
Tank High Level, Start/Stop (HL):
This contact is used to start and stop the system via an optional tank level controller. The contact used to activate this input must be a normally open TYPE-C DRY CONTACT. When the contact is open the system will operate and when the contact closes the system will be placed in the STANDBY (Tank High
Level) mode. To reduce the ON/OFF cycling of the system a dead band must be incorporated in the level controller or a second level contact can be installed and tied in the intermediate level terminal.
CAUTION Contacts must be a TYPE-C DRY CONTACT. Damage to the controller will occur if powered contacts are used.
Tank Intermediate Level (INT):
This contact is used in conjunction with the tank high level contact. A two point level controller can be used. The level controller contacts must be a normally open TYPE-C DRY CONTACTS. As the tank is filling the intermediate level contact will close and then the high level contact will close placing the system in the STANDBY (Tank High Level) mode. As the water is being consumed, the water level will drop. The tank high level contact will open, and then the intermediate level contact will open. The system will restart at this point. This configuration will provide a dead band reducing the ON/OFF cycling of the system.
CAUTION Contacts must be a TYPE-C DRY CONTACT. Damage to the controller will occur if powered contacts are used.
Remote Standby (RS-B):
This contact is used to interlock pre-treatment / post-treatment equipment with the system. The contact must be a normally open TYPE-C DRY CONTACT. When a pre-treatment / post-treatment device such as a softener goes into regeneration the contact closes placing the system in the STOP mode. When the regeneration cycle is completed and the contact opens the system will restart in whatever mode it was in before. When multiple pre-treatment / post-treatment devices are used the electrical connections are to be terminated in parallel.
CAUTION Contacts must be a TYPE-C DRY CONTACT. Damage to the controller will occur if powered contacts are used.
MAN-4400MCOLD (rev. J) page 99 of 103
4400M Digital RO System
Drain Valve Switch Contact:
The valve switch contact can be used to install an auto switch or a jumper for drain function.
This switch allows the operator to either manually divert the product water to drain, when set in the Drain Position, or automatically divert to drain on programmable poor quality setpoint during manual or auto flush operation and when the system is in the STOP or STANDBY tank full mode. For automatic diversion, the optional divert to drain solenoid valve must be installed.
The switch contact must be a normally open TYPE-C DRY CONTACT.
CAUTION Contacts must be a TYPE-C DRY CONTACT. Damage to the controller will occur if powered contacts are used.
Drain Valve Contact:
The valve contact is used to connect a solenoid divert valve(s). The valve can be air solenoid to activate pneumatic valves or two solenoid valves, one normally open and one normally closed.
The normally closed valve should be plumbed to the tank or loop and the normally open to the drain. The valve will only activate when the product water quality is below the programmable setpoint (fail-safe operation).
CAUTION The contact is rated for a maximum load of 1.0 Amp @ 24VAC when the standard 150VAC step-down transformer is used. If a higher current is required (up to maximum of 5.0 Amps @ 24VAC) the capacity of the stepdown transformer should be increased.
NOTE Each individual panel can be custom designed or modified to suit the customer’s needs. Please contact your local representative for options.
