User benefits of on-line
ammonia monitoring
The task of managing the quantity of water resources and the
quality of drinking water today is unimaginable without online instrumentation that helps water utilities manage, treat
and deliver drinking water to consumers.
On-line monitoring provides plant operators with an early
warning of any changes to the treatment process, enabling
operational decisions to be made in near real-time. This level
of process control is not possible with manual testing alone,
where potentially important events that occur between less
frequent manual sampling can be missed.
Users of the Aztec 600 Ammonia analyzer benefit from:
• Improvements in process control
–– enables operational decisions to be made in near realtime.
• Improvements in process reliability
–– detect process failures before they affect the quality of
the water leaving the plant.
• Process optimization for water quality
–– increased plant efficiency.
• Potential capital and operating cost reductions
–– reduction in chemical and energy usage.
• Continual monitoring of remote or un-staffed sites
–– improved response times and reduced visits saving
money and time whilst lowering carbon footprint.
• Improved reporting
–– analyzer audit trail data can be used to assure
customers and regulators of process efficiency and
consistent product quality.

Reliable measurement
The Aztec 600 Ammonia is an on-line colorimetric analyzer. It
has been designed for ease-of-use and maintenance
simplicity, while offering the benefits of flexible
communication and advanced data acquisition.
The Aztec 600 Ammonia can measure up to 4 samples per
hour using the indophenol blue chemistry to measure
ammonia and ammonium ions..
A fully-programmable multi-stream option is available,
providing up to 3-stream capability with user-programmable
stream sequencing.
Fluid handling
A single piston pump provides all the sample and chemical
fluid handling for measurement, mixing and disposal. The
pump is stepper motor controlled for repeatability and
precision.
This ‘motorized syringe’ approach has the added benefit of
wiping the optical cell on every movement of the piston,
resulting in a highly efficient automatic cleaning process.
This is particularly important when measuring waters where
optical contamination can be a real issue without having
stringent automatic cleaning.
Measurement technique
The optical cell is rinsed thoroughly with sample before
measurement, eliminating dead zones and enabling multistream measurement across different samples without cross
contamination.
To correct for any natural coloration of the sample, the
background absorbance of the sample is measured prior to
the addition of any color-forming reagents to provide a
sample blank.
Reagents are then added and mixed to produce a colored
solution that can be measured and converted to a
concentration value.
Sample outlet(s)
to waste
Instead of using a mechanical stirring system, the piston and
optical sensor is utilized further by drawing in air after the
sample and reagents are introduced. This provides turbulence
and efficient mixing without any of the cost and maintenance
drawbacks of mechanical and electrical mixing systems.

The Aztec 600 Ammonia analyzer has the capability to enable

Simple to maintain
The powerful and user-friendly Windows menu-driven
software enables user’s to operate the analyzer with the
minimum amount of training.
The Aztec 600 colorimetric range is designed to be as
maintenance-free as possible. The inherent product design
and auto-calibrating features reduce the amount of
maintenance required to external cleaning of sample lines,
changing of reagents and annual servicing.

monitor tubing and glass cell.
All parts are provided in convenient maintenance kits.
Solution replacement
The Aztec 600 Ammonia analyzer uses a total of
approximately 25 ml of sample, per analysis: 7.5 ml for the
actual measurement and the remainder for cell rinsing. The
automatic 2-point calibration substitutes the sample with the
calibration solutions at the same amount.
Windows-based interface
These menus include data logging and graphical trending
screens, operation command screens, full setup configuration
screens and a range of self-diagnostics (including full
calibration and operating status screens).
Historical logs provide operators with access to alarm logs
and audit trail data. Process data and historical logs are
archived securely to a removable SD card.
All information is displayed clearly on the easy to read 145 mm
(5.7 in.) color LCD display and is available in a range of
languages.
Above 0.5 ppm NH3 the Aztec 600 Ammonia dilutes samples
automatically with de-ionised water, to maximize the
measurement range. The dilution ratio between sample and
de-ionised water is user-configurable between: 1:1, 1:2, 1:3, 1:4.
