NITRATE & NITRITE MONITORING IN 

WASTEWATER TREATMENT PLANTS 

Use Aquamonitrix® in your wastewater treatment plant (WWTP) for

+ Remote, real-time monitoring of nitrate and nitrite levels in effluent discharge, ensuring operational reliability and compliance with licencing obligations

+ Gaining better insights into the impact of operational variables, allowing process efficiency monitoring and optimisation

Key Advantages for WWTP Monitoring

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

+ Real-time data transmission to your SCADA communication system – allowing for remote supervision and diagnostics – so you know when you don’t need to go to site

+ Laboratory-quality accuracy and precision (or better) in the field

+ Robust design capable of withstanding the WWTP environment – non biofouling

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

+ Simple operation and servicing (with training by video). Low-skill and frequency maintenance requirements, suiting agnostics service contracts

+ Portable and light-weight 

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

key features

YOU WILL BENEFIT FROM

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

+ Real-time data, allowing timely intervention to avoid pollution events, minimising the potential for fines and reputational damages

+ Cost saving through process optimisation

+ Enhanced service offering in WWTP DBO tenders, particularly in nitrate-sensitive locations

ACCELERATING THE DRIVE TO NET ZERO

Activated sludge process optimisation

Nitrite-based aeration control, enabling ‘shortcut’ nitrogen removal

+ Ultra-robust design, capable of withstanding the challenging aeration tank environment

Reduce energy consumption for financial savings and lower carbon footprint 

In conventional wastewater treatment plants, aeration is required to enable the conversion of ammonia to nitrate and finally to nitrogen. This is a highly energy intensive process, with aeration accounting for over 40 to 50% of total site power consumption.

‘Shortcut’ nitrogen removal reduces energy consumption

+ Online nitrite measurements by Aquamonitrix® are used to reduce reactor sludge retention time

+ Nitrate production is minimised by stopping the nitrification process at nitrite, which is then converted to nitrogen gas

+ WWTP exit effluent contains lower nitrite, nitrate and total nitrogen concentration*
