The possibility of an electromagnetic field (EMF) influencing the intensification of phosphorus (P) and organic compound (COD) removal from domestic wastes was investigated. The impact of an EMF as the only factor or as an intensifying element in steel packing systems that limits pollutant concentrations in the treated wastes was analysed. The research was conducted in three stages in a static system at the laboratory scale. A significant dependence between the kind of system used, time of detention, flux intensity electromagnetic field and the effectiveness of the pollutants limitation were observed. Most efficient was the system that combined simultaneously steel filling and under electromagnetic flux intensity O = 100.0 µWb and O= 135.0 µWb. In the case of 48 hours the reaction time let to remove from the system the whole phosphorus amount as P-PO4 for treated sewage. These technological variants seem to be the most effective as for Ptot and COD.
