FIELD: purification of industrial and domestic waters. SUBSTANCE: hydrogen peroxide is introduced into a filter with metallic media of elements of the d-subgroup of the periodic chart at a definite distance (0.1 to 0.5 of the layer length) in the direction of water flow, and the process is accomplished at a pH-value within 2.0 to 3.35 and temperature up to 65 C. EFFECT: enhanced degree of water purification by 6 to 9 times, accelerated process by 10 to 15 times. 7 cl, 1 tbl
