FIELD: process engineering.
SUBSTANCE: invention relates to rapid filters for cleaning natural waters and sewage of colour, silt content, iron and oil products. Proposed filter comprises casing, distributing and collecting system, mineral granular filter material, electropositive and electronegative electrodes. In compliance with this invention, said electrodes represent rods arranged vertically in filter material. Note here that electropositive and electronegative electrodes form alternating lines parallel to casing face wall arranged staggered. Electronegative electrodes are made from aluminium, while electropositive electrodes are made from copper, the distance between them making 200-240 mm.
EFFECT: higher efficiency of cleaning.
