B Basic information (reverse osmosis system)

1 | Laws, regulations, standards

In the interest of good health, rules cannot be ignored when it comes to the processing of drinking water. This operation manual takes into consideration the current guidelines and stipulates information that you will need for the safe operation of your water treatment system.

Among other things, the regulations stipulate that



only approved specialist companies are permitted to make major modifications to water supply systems



and that checks, inspections and maintenance on installed devices are to be performed at regular intervals.

2 | Water

There is no chemically pure water in nature. Even in the atmosphere, rain water absorbs various substances that change the properties of the water to a greater or lesser degree. This process continues as the water passes through the ground layers, with the result that the water is enriched with increasingly large quantities of materials. Carbon dioxide (CO

) is particularly important here, since this substance increases the dissolving capability of the water even more. Consequently, drinking water contains quantities of dissolved sodium, potassium, calcium, magnesium, iron, manganese, copper, zinc, chlorides, fluorides, sulphates and also nitrates, nitrites, phosphates and silicates that vary greatly from location to location.

Due to dynamic substance and water cycles, harmful elements, are increasingly being released into the natural environment.

These are only partially and slowly broken down by natural effects.

Consequently, these elements build up in the groundwater and surface water over the course of time. Removing them from natural water deposits again represents a particular challenge.

Grünbeck faces this challenge with the aim of producing unpolluted drinking and industrial water.

The water works provide us with pure drinking water that is suitable for consumption. However, if the water is to be used for technical purposes, further treatment is frequently required.

Fig. B-2: Reverse osmosis principle

In the osmosis process, aqueous solutions of different concentrations are separated by a semi-permeable membrane. In keeping with the law of nature, the concentrations will tend to equalise. What is referred to as "osmotic pressure" is generated on the side of the higher original concentration.

In case of reverse osmosis, this osmotic pressure is countered by a higher pressure. The consequence:

The process runs in the opposite direction.

A particular advantage of the reverse osmosis technology compared to other water treatment processes is the fact that apart from the removal of dissolved salts, bacteria, germs, particles, and dissolved organic substances are also reduced.

Reverse osmosis system

AVRO 125 TS/TL

2 | Functional description

Via the 5 µm drinking water filter (filter element), the water is directed to the inlet of the feed water section. The water flows to the highpressure pump via the inlet solenoid valve with a downstream pressure switch for minimum pressure. By means of an adjusting valve, the pressure generated by the pump is reduced to the required operating pressure and the water is directed to the membrane.

The membrane separates the water into the partial flows permeate and concentrate. A partial flow of the concentrate is returned to the feed water via an orifice regulating independently of pressure and thus ensures a steady flow over the reverse osmosis membrane and increases the economic efficiency of the reverse osmosis system.

At the same time, the concentrate volume flow is run via an AVRO treatment module. where seed crystals are formed at a cathode due to the application of direct current. These seed crystals are then washed out with the residual concentrate and thus the reverse osmosis membrane is protected from clogging. Whenever the system is switched off (tank full) or in case of disturbances, the substances retained on the membrane are flushed off by means of the inlet solenoid valve and a solenoid valve switched in parallel to the control valve for concentrate.

The hydraulic set-up of the system is designed in a way that the concentrate volume and the permeate volume are registered by means of flow sensors and are displayed in the control unit.

The system recovery can also be called up in the control unit.

1) The permeate produced is fed into a light-tight reservoir. A level control with three switching contacts is integrated in the tank. In order to supply the consumers with permeate, a centrifugal pump made of high-performance plastics including pressure switch and diaphragm expansion tank is integrated in the system as pressure booster system.

3 | Intended use

The reverse osmosis system AVRO 125 TS/TL is used for demineralising drinking water. The water is primarily used for industrial applications.

The permeate capacity of the system depends on the temperature and is defined at 15 °C. The permeate outputs can fall (falling temperature) or rise (rising temperature) by up to 3 % for each °C rise or fall in the feed water temperature.

The system is adjusted to the permeate requirements to be expected at the installation site, it is not suitable for major deviations.

Only operate the system if all components are properly installed.

Safety devices and equipment must NEVER be removed, bridged or tampered with.

Appropriate application of the device also implies that the information contained in this operation manual and all safety guidelines applying at the installation site be observed. Furthermore, the maintenance and inspection intervals have to be observed.

3.1

System shutdown

If the system is shut down for more than 14 days, the reverse osmosis system must be preserved by Grünbeck's technical customer service/authorised service company. The maximum time, the system can remain in the preserved condition is 6 months.

In case the down time is longer, the system must be preserved again in regular intervals by Grünbeck's technical customer service/authorised service company. Prior to resuming operation, the preserving agent must be flushed from the system.

D Installation

1 | General installation information

The installation site must offer adequate space. A foundation of a sufficient size and adequate load carrying capacity has to be provided.

The required connections must be provided prior to the installation.

For dimensions and connection data, please refer to table C-1.



Note: Also observe the operation manuals that have been supplied with the optional accessories (see chapter C, 5.2) for your system

(if applicable).

1.1 Water connection When installing the reverse osmosis system AVRO 125 TS/TL, certain rules must always be observed. Additional recommendations are given in order to facilitate the handling of the system. The installation instructions described below are also illustrated in fig. D-2.

Binding rules

The installation of a reverse osmosis system AVRO 125 TS/TL represents a major interference with the drinking water system.

Therefore, only authorised experts are allowed to install such systems.



Please observe the local installation guidelines and the general regulations.



Install a drinking water filter (e.g. BOXER KD) upstream of the system.



Install a system separator upstream.



Install an activated carbon filter upstream, if required.



Provide a drain connection (minimum DN 50) to discharge the concentrate.



Note: If the concentrate is directed to a lifting system, the delivery rate of the lifting system should at least be 500 l/h.

Warning! The installation site must have a floor drain. If no floor drain is available, an adequate safety device needs to be installed (refer to chapter C, no. 5.2 Optional accessories).

Warning!

Floor drains that discharge to a lifting system will not work in case of a power failure.

Recommendation

Install a sample valve immediately before and after the reverse osmosis system AVRO 125 TS/TL. This simplifies the sampling for the regular quality control (functional check).

2 | Preliminary work

1. Unpack all system components.

2. Check for completeness and soundness.

3. Install the reverse osmosis system AVRO 125 TS/TL at the intended location.

3 | How to connect the system to the water supply



Connect the feed water to the system (refer to fig. D-2, no. 3).



Only for AVRO 125 TL: Connect the permeate line to the system and lead it to the on-site tank (refer to fig. D-2, no. 2).



Note: Permeate line must be made of corrosion-resistant material.



Connect the concentrate line to the system (refer to fig. D-2, no. 1).

Run the hose with a gradient to the drain and connect in accordance with DIN 1988 (free outlet).



Note: For connection of the system we recommend detachable screw connections. Furthermore, the connection is to be designed in such a way that the housing flap of the control unit can be folded back.

Grünbeck recommends: optionally

Connection block for RO 125 K/AVRO 125 752

Connection set for RO 125 K/AVRO 125

Caution!

If withdrawal/supply points (e.g. on-site tank) of permeate from the RO-125K are below the connection level of the system, a pressure maintaining valve must be installed in the permeate line to protect the permeate tank against siphoning.

E Commissioning

The work described below is only allowed to be performed by trained experts. We recommend having Grünbeck‘s technical service/authorised service company start up the system.

1 | How to flush the system



Note: For the duration of storage and transport, the membrane is protected by means of a preserving agent. This preserving agent must be flushed out before the first commissioning. In order to prevent the system from being switched on beforehand, it is locked electronically.

1.1 Mounting the flushing line

Disassemble the permeate line from the collection tank (refer to figs. E-1, E-2 no. 1) and route it to the drain in a separate hose.

4 | Operation of reverse osmosis

4.1 How to set the system recovery

A certain part of the feed water must be rejected in order to prevent the membrane from clogging due to scaling. The ratio of the produced permeate volume to the feed water volume is called recovery.

4.1.1 How to set the permeate volume



Switch on the system at the control unit by pressing the "ON" button.



Use the adjustment valve operating pressure (refer to fig. F-3, no. 1) to throttle the pump in such a way that the specific permeate flow rate 125 l/h is achieved.



Note : The current permeate flow can be displayed via the control unit (refer to chapter F, point 2.1 Reading the operating status.

AVRO 125 TS/TL

4.1.2 How to set the concentrate volume



Set the concentrate flow at the concentrate needle valve (refer to fig. F-4, no. 1).



The concentrate flow in a standard system has to be set in a way, that a recovery of 50 % is attained (125 l/h of permeate flow, 125 l/h of concentrate flow).

 Note: The current concentrate flow and the recovery can be displayed via the control unit (refer to chapter F, point 2.1 Reading the operating status).

Caution!

If the recovery setting is not maintained, scaling

(precipitation of dissolved salts) occurs on the reverse osmosis membrane.



Measure water values of feed water, permeate, concentrate after

10 minutes and enter them in the operating log.



Switch off system.

H Maintenance and care

1 | Basic information

In order to guarantee the reliable function of the systems over a long period of time, some maintenance work has to be performed at regular intervals. All regulations and guidelines which apply at the installation site must be strictly adhered to.



Check the quality and the system volume flows every day.



Maintenance has to be performed by Grünbeck’s technical customer service/authorised service company or by a specialised company. Maintenance is subject to the load, but at the latest has to be performed once a year.



An operation log and the corresponding test log must be kept in order to document the maintenance work performed.



Note: By concluding a maintenance contract you ensure that all maintenance work will be performed in due time.

The maintenance work performed must be documented in the checklist, refer to appendix "Operation log".

2 | Inspection (functional check)

You can perform the daily inspections yourself.

Please refer to the following summary for the tasks to be performed within the framework of an inspection.

Summary: Inspection work



Determine inlet water values.

(Water test kit "total hardness" or carbonate hardness).



Determine the permeate quality. Either at the display if a conductivity monitoring device is installed or by means of a manual conductivity meter.



Read the recovery.

 Note: Minor deviations are normal and cannot be prevented technically. In case of considerable deviations from the standard, notify Grünbeck's technical customer service.



Take the remaining time of AVRO treatment unit’s maintenance interval into consideration (refer to chapter F, point 2.1). If the remaining time is < 100 hours, notify Grünbeck’s technical service/authorised service company to have the treatment module replaced.



Take the remaining time of the maintenance interval into consideration. (Chapter F - point 2.2 Reading the operating state). In case the remaining time of the maintenance interval is < 30 days, inform

Grünbeck's technical customer service about the impending service.

AVRO 125 TS/TL



Make sure that there are no leakages from the system to the drain

(all 3 waves can be seen on the display when the system is switched off (refer to fig. F-2, point 5). Solenoid valves are not tightened, visible in the display (refer to fig. F-2, no. 9 and 10).

In this state, no water must creep to the drain.



Note: There can be increased water consumption by the system if the solenoid valves are leaking. The recovery will be reduced.

3 | Maintenance

According to DIN 1988 part 8 / A 12, maintenance work at the systems is only allowed to be performed by Grünbeck’s technical service/authorised service company or an approved specialist company.

For this kind of systems, an operation log - a checklist has to be kept.

In this operation log, the customer service technician records all maintenance and repair work performed. In case of malfunctions, this log helps to identify possible sources of error. In addition, the log documents the proper system maintenance.



Note: Make sure that all maintenance work is recorded in the operation log as well as in the corresponding test report.

Summary: Maintenance work



Replace the 80/50 µm resp. 5 µm filter elements.



If necessary, replace the filter element of the activated carbon filter.



Check the permeate quality; flush or replace the membrane, if necessary. So-called flushing instructions (order no. 700 950) are available for authorised service personnel.



Replacement of AVRO treatment unit, if necessary

(limit value: 3000 h or 5 years).



Clean the solenoid valves - check their function.



Check the flow volumes and recalibrate the water meter.



Check the state of the entire system and check for tightness.



Mechanical resp. electrical functional and performance check of all aggregates (pumps, valves).



Prepare a written maintenance log on the state and function of the system and the maintenance work performed, incl. evaluation and assessment of the operating values and water analysis results.
