Domestic ,wastewater, typically has a total ,nitrogen, content that is about one-fifth of the BOD, with typical ,nitrogen, concentrations ranging from 20 to 70 mg/L. About 60% to 70% is ,ammonia,-,nitrogen,, and 30% to 40% percent is organic ,nitrogen,, with less than 1% nitrite and nitrate ,nitrogen, (Tchobanoglous et al. 2003).

Organic ,nitrogen, is released as ,ammonia nitrogen, when bacteria decompose organic matter. ,Ammonia, is lost as a gas or converted to nitrites, which are rapidly oxidized to nitrates by bacteria. Nitrates can be reduced back to ,ammonia, by bacterial reduction. This cycle continues unless retarded by a bacterial inhibitor.

ammonia nitrogen, oxidized in advanced ,wastewater, treatment because the POTE discharge effluent has acidic nature of pH 6.6 (Metcalf & Eddy, 2015). Nitrate is th e hydrogen electron acceptor. As the algae production takes place in lake due to photosynthesis and therefore limited nutrients must be available for the control of eutrophication.

The discovering of anaerobic ammonium oxidation (anammox) process led to the development of autotrophic nitrogen removal systems for the treatment of effluents with low C:N rate. The anammox processes provide an efficient way to remove high concentrations of ammonium compounds from industrial and urban wastewater and covert them to dinitrogen.

In water, one of the major forms of nitrogen is ammonia nitrogen (NH 3 -N). NH 3 -N is essential to living organisms, but exceeding threshold level could cause environmental pollution (Rožić et al., 2000). A large amount of NH 3 -N could cause serious disorder of natural materials circulation, which threats human health.
