Since ammonia nitrogen is an algal nutrient, algae are capable of extracting this nutrient from the waste water. Algae growing in waste water stabilization ponds utilize ammonia nitrogen of the waste water to form cell tissue in the presence of sunlight. Adequate carbon dioxide and some nutrients are also required in this process.

The SAC resin has a higher selectivity for the amine and ,ammonia, constituents in the ,wastewater, stream than for the ,acid, constituents. This is not true for alkali in the ,wastewater,; therefore, ,neutralization, with sodium hydroxide, potassium hydroxide, or other caustic chemical is not recommended until ,after, ion-exchange treatment.

Ammonia-Nitrogen Removal by Breakpoint Chlorination
Ammonia-Nitrogen Removal by Breakpoint Chlorination

Ammonia in wastewater and water was oxidized by chlorine to chiefly nitrogen gas with a residual NH 3 -N concentration of less than 0.1 mg/i. The chlorine was applied in the gaseous state to a stream of water and base before mixing with the wastewater, or as a solution of hypochlorite.

28/8/2020, · Abstract. The recovery of ammonia–nitrogen during wastewater treatment and water purification is increasingly critical in energy and economic development. The concentration of ammonia–nitrogen in wastewater is different depending on the type of wastewater, making it challenging to select ammonia–nitrogen recovery technology.

9/5/2019, · Therefore, conventional ,wastewater, treatment processes are focused principally on removal of ,nitrogen, from ,wastewater,, most commonly by biological nitrification and denitrification. Newly developed processes, such as Anammox, can convert ,ammonia, and nitrite to ,nitrogen, gas directly under anaerobic conditions (Jetten et al., 1998).

According to the characteristics, functions, requirements and characteristics of wastewater discharge, the wastewater contains certain toxicity, B/C is relatively low, and ammonia nitrogen is high. Therefore, the denitrification and strong oxidation should be used to increase the B/C ratio of wastewater above 0.3.
