NITRATE & NITRITE MONITORING IN 

WASTEWATER TREATMENT PLANTS 

Aquamonitrix® nitrite and nitrate analyser for wastewater treatment plants

+  Remotely monitor your WWTP, with 24/7 surveillance of nitrate and nitrite concentrations. Have the peace of mind that your treatment processes are performing within specification and the reassurance of knowing that you don’t need to go to site.

+ Reduce energy consumption associated with aeration by using real-time nitrate and nitrite data to improve process control in biological nitrogen removal and optimise ‘short-cut’ methods such as nitrite shunt and anammox processes.

+ Respond dynamically to changing conditions in wastewater entering the plant.

+ Get instant alarms and alerts when effluent nitrate levels exceed permissible limits, so you are always the  first to know about a pollution incident.

Key Advantages for WWTP Monitoring

+ Remote, autonomous sampling and analysis – as frequently as once every 15 minutes

+ Both nitrate and nitrite measured from the same sample

+ Laboratory-quality accuracy and precision

+ Robust in-built sampling system can handle wastewater without the need for sample pre-treatment or  high-cost add-on sampling equipment

+ Resistant to biofouling

+ Stable calibration and maintenance-free operation over sustained deployment periods

+ Simple operation and servicing. Low-skill and frequency maintenance requirements, contributing to low opex and lifetime costs

+ Portable and light-weight – simple ‘plug n’ play’ deployment – no site preparation required, can be fully up and running within two hours

+ Real-time data transmission to your SCADA communication system – allowing for remote supervision and diagnostics

+ Simple ‘plug n’ play’ deployment – no site preparation required, be fully up and running within hours

key features

YOU WILL BENEFIT FROM

+ A better understanding of real-time nitrate and nitrite dynamics as the intermediates in biological nitrogen removal (secondary treatment). This is the single most energy-intensive conversion in conventional wastewater treatment, and an enhanced understanding will enable you to reduce aeration energy requirements through better process control and  optimisation.

+ Remote supervision with real-time data, providing peace of mind and allowing timely intervention to avoid pollution events, minimising the potential for fines and reputational damages

+ Reduced personnel time and costs and chemical consumption compared with manual sampling and lab analysis

 

The drive to Net Zero 

In conventional biological nitrogen removal, highly energy-intensive aeration is required to convert ammonia to nitrate, nitrite and finally to nitrogen gas. 

‘Shortcut’ biological nitrogen removal (SBNR) reduces energy consumption

+ With the nitrite shunt approach  the ‘shortcut’ is achieved by stopping the nitrification process at nitrite, which is then reduced directly to nitrogen gas.

A variation of  SBNR also inhibits nitrate formation but then uses Anammox bacteria. In the first step, half the ammonium is oxidised to nitrite, and in the second step, the remaining ammonium converted to nitrogen gas.
