FIELD: water treatment. SUBSTANCE: water to be freed from impurities is fed on filter element made from porous sintered titanium, whose surface on the water supply side is covered with titanium dioxide layer and amorphous iron hydroxide layer. Water is treated by constant electric power voltage no higher than 10 v imposed to filter element or to filter element and filter housing, and filter element is further regenerated by inverting electric charge polarity and varying its value. EFFECT: enhanced treatment efficiency. 3 ex
