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 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*
