In this work, the exchange capacity and the selectivity of different ion-exchange products regarding the ammonium ions in treatment processes were measured; the regenerative preparation compounds influence on efficiency of conduction of ion-exchange products regeneration was determined. The adsorption processes were adapted to the known technological schemes of sewage and polluted surface water treatment that was polluted with ammonium ions. There were measured the technological aspects of water treatment by using adsorption on natural dispersed sorbents. The technological schemes of drain water treatment from ammonium ions were developed. The method of simultaneous removal of highly concentrated nitrogen and phosphorus was analyzed by physical and chemical precipitation, forming struvite, a by-product of magnesium ammonium orthophosphate hexahydrate. The analyses were conducted at various molar ratios of magnesium and phosphate ions and at various pH values. The comparative thermal analysis of chemical precipitation products and pure struvite was performed. The optimal conditions were identified to experience the maximum efficiency of simultaneous removal of ammonium nitrogen and phosphate ions from wastewater, forming MgNH₄PO₄·6H₂O.
