Ammonia in wastewater is a growing concern due to its detrimental impact on aquatic ecosystems. When discharged to receiving bodies of water, ammonia causes algal blooms that deplete dissolved oxygen and release toxins, destroying aquatic life. Regulatory agencies are requiring industry to treat ammonia in their
Aug 04, 2021· The new BNR treatment facility is the size of 18 football fields and normally treats about 130 million gallons per day but can treat as much as 330 million gallons of wastewater a day in winter months. The project removes more than 99% of ammonia from the Sacramento region’s wastewater.
Ammonia can reach high levels in wastewater due to bacterial action. It is important to monitor ammonia in wastewater as once the effluent is released high levels of ammonia can be detrimental to aquatic life. Removal of ammonia from wastewater is carried out using the Nitrification Process to convert ammonia to nitrate.
The industrial ammonium ion selective sensors in the AB 6410 (3/4"-1" MNPT), AB 8410 (1"MNPT Twist Lock) or AB 5410 (Sanitary or HOT-TAP) together with the a suitable mating dissolved ammonia gas resistant pH sensor can be used to compute the total unbound ammonia species (see graph linked below for visualization):
