FIELD: water purification. SUBSTANCE: invention is aimed at purifying water from petroleum products, microorganisms, and other foreign inclusions. Water is proposed to be passed through installation with filler at a rate 0.1 to 50 $$$ followed by regeneration of filler. As the latter, ferroceramics are used. Contamination is being removed with regenerating solution using polarization of the filler bed with electric field having intensity at least 30 V/cm in at least one regeneration stage. EFFECT: enhanced purification process. 5 cl, 4 tbl
