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.
