Reduced ,forms of nitrogen,, particularly ,ammonia, (NH 3), are vital to life. Before the early 1900s, all reduced N came from biological ,nitrogen, fixation by microbes. This landscape changed in the early 1900s with the invention by Haber and Bosch of an industrial process to reduce N 2 to NH 3 (N 2 + 3H 2 ⇄ 2NH 3).

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.

Ammoniacal ,nitrogen, is one of the ,wastewater, contaminants, which can be found in many types of ,wastewater,. Excessive ammoniacal ,nitrogen, in water body may lead to eutrophication, which induces the growth and decay of excessive plant and algal, and caused degradation of the water quality [1].Notably, algal blooms may limit light penetration.

Ammonia, is a compound ,of nitrogen, and hydrogen with the formula NH 3.A stable binary hydride, and the simplest pnictogen hydride, ,ammonia, is a colourless gas with a distinct characteristic of a pungent smell. It is a common nitrogenous waste, particularly among aquatic organisms, and it contributes significantly to the nutritional needs of terrestrial organisms by serving as a precursor to ...
