dissolved in a liquid through a mass transfer. In the case of SW, which is the liquid phase, ammonia is used as gas. In the AS process, the wastewater is aerated after mixing with alkali at pH over 8.5, which allows for easier ammonia stripping. Ammonia is then recovered by an adsorbing unit, filled with a sulfuric acid solution, as ammonium sulphate.

This is because leachates contain very high ammoniacal nitrogen concentrations, are usually very acidic, are often anoxic and, if received in large volumes relative to the incoming sewage flow, lack the Phosphorus needed to prevent nutrient starvation for the biological communities that perform the sewage treatment processes.

It was also found that stripping of ,ammonia, and carbon dioxide in the cooling tower can influence the cooling loop pH significantly. The effects of the NH3 mass transfer coefficient on cooling loop pH appear to be more significant at lower values (e.g., kNH3 < 4×10-3 m/s) when the makeup water alkalinity is low (e.g., <90 mg/L as CaCO3).

These chemicals can come from agricultural runoff, ,wastewater, discharge or industrial runoff. Mining operations (particularly coal) produce acid runoff and ,acidic, groundwater seepage if the surrounding soil is poorly buffered ²². ,Wastewater, discharge that contains detergents and soap-based products can cause a water source to become too basic.

A high-salts and high-,ammonia acidic wastewater, has the pH of 3~5, conductivity of 100000~200000μs/cm and ,ammonia, of 500~5000mg/L. In addition, it also contains some trace heavy metal ions such as Pb, Hg and Cd. This type of ,wastewater, is high-salts, high-,ammonia wastewater, which needs to be recycled.
