A study of the reagent removal of phosphates from domestic wastewater is presented. The research involved works, the authors of which describe methods for extracting phosphorus compounds from water. The article compares the removal of phosphates from wastewater by various methods in comparison with reagent methods. The analysis of existing technologies for regenerative dephosphorization of wastewater has shown that a promising direction is the search for new reagents for extracting phosphates from wastewater. Preference is given to such reagents as calcium oxide and hydroxide, iron chloride and sulfate, aluminum sulfate. The most eff ective for binding phosphates is the calcium cation, since a greater amount of hardly soluble compounds are formed with it.
