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.
+ Control nitrous oxide emissions by using real-time nitrite ( and nitrate) data to improve process control in biological nitrogen removal
+ 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.
Advantages for WWTP Nitrate & Nitrite Monitoring
+ Aquamonitrix® measures nitrate and nitrite simultaneously, yet selectively,
in real-time.
+ Aquamonitrix® has been proven to retain accuracy and precision of >90% – for both nitrate and nitrite analysis – over long deployments in highly challenging septic effluents (US EPA/MASSTC EVT)
+ The robust in-built sampling system can handle wastewater without the need for sample pre-treatment or high-cost add-on sampling equipment
+ This allows for plug n’ play’ deployment. No site preparation is required, so your analyser can be fully up and running within two hours
+ Calibration remains table over long deployments – even when the analyser is moved from one location or sample matrix to another
+ The analyser is lightweight and portable, allowing for easy monitoring at different points around a plant
+ Near continuous monitoring is possible, with remote, autonomous sampling and analysis – as frequently as once every 15 minutes
+ Real-time data transmission to your SCADA communication system / choice of data management or telemetry system and/or the proprietary Datamonitor- platform allowing for real-time results & analyser self-diagnostics direct to your PC
+ Simple operation and servicing & low-skill and low-frequency maintenance requirements all contribute to low opex and lifetime costs
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.
