The recent statistics show that the world's population is rapidly increasing. This increase negatively affects the water resources and it increases the water demand progressively. Along with the increase in the world's population, the insensible use of water resources, pollution, and drought lead to the increasing reduction of water resources. Due to these factors, all countries, primarily ...

However, the potential impacts of ZnO NPs on ,wastewater, nitrogen and phosphorus removal with an activated sludge process are unknown. In this paper, short-term exposure experiments were conducted to determine whether ZnO NPs caused adverse impacts on ,biological nitrogen and phosphorus removal, in the unacclimated anaerobic-low dissolved oxygen sequencing batch reactor.

For these reasons, orthophosphate is the main concern in the process of phosphorus removal from ,wastewater,. The ionization equilibrium of phosphoric ,acid, restricts the ionization of orthophosphate in water, while producing H3P04, H2P041, HP042 1 and P04. The concentration distribution of each phosphorous group varies with the pH value.

The result shows that 5.5 g iron was consumed to treat a cubic metre of wastewater, i.e. 5.5 mg/L. It has been reported that when using the synchronous precipitation dephosphorization process, more than 30 mg/L ferrous or ferric iron was needed to achieve the phosphorus content of less than 0.5 mg/L (Liu et …
