Fields of application

Ammonium measurement with Alyza IQ NH4

Indophenol method according to DIN 38 406

Wastewater treatment plant effluent monitoring:
  • High measuring accuracies even at low concentrations
  • Easy handling due to optimized user interface
  • Increased employee protection by safe exchange of reagents
River monitoring:
  • Long lifetime of reagents due to minimum consumption
  • Minimal maintenance effort reduces work and travel times
  • Full remote access via IQ Web Connect, at any time

Orthophosphate measurement with Alyza IQ PO4

Molybdate-Vanadate method (Yellow method)

Precipitation control:
  • Automatic cleaning reduces maintenance effort and increases operational safety
  • Reduction of precipitant costs without overdosing by reliable and fast measurement
  • One instrument for up to two sample streams
Wastewater treatment plant effluent monitoring:
  • Precise results via automatic 1- and 2-point calibration
  • Easier everyday life due to self diagnostics with display of reagent lifetime
  • Requirements for further decreasing effluent values are not a problem due to low measuring range

The Wet Chemistry revolution is now.

With WTW designed disruptive technology at the heart of the new Alyza IQ range, extremely accurate and reliable measurement results have been realized with extremely low reagent use, maintainance and downtime.  

Benefits:

Sensor vs. Analyzer

Today's available NH4 sensors are used for state-of-the-art optimization of wwtp aeration basins. Nevertheless wet chemical analyzers have their justified existence for the following reasons:

  • Certain parameters like phosphate can only be detected by wet chemical methods
  • Measurements at very low concentrations frequently need a standard method for accurate determination of the parameter concentration.
One example for the detection of Ammonium at very low concentrations is the indophenol-blue method which is used with the new Alyza IQ – Ideally suited for the detection of NH4 in rivers and lakes.
