FIELD: process engineering.

SUBSTANCE: invention relates to machine building and may be used for water treatment. Proposed device comprises housing with detachable plate-like cover with its bottom directed upward, filtration element, inlet union, outlet branch pipe fitted in said cover, and bell-shaped settler provided with drain plug fitted at its bottom, its narrow section being directed downward. Cylindrical perforated barrel is fitted inside the housing. Housing top section has a ring with outer surface in contact with housing inner surface and inner surface in contact with cylindrical barrel outer surface. Filtration element is shaped to cylinder with axial bore and accommodated inside cylindrical barrel. UV-lamp and helical-screw-shaped turbuliser are arranged inside filtration element along its axis. Note here that helical screw ID equals that of UV-lamp while screw OD equal filtration element ID. Inlet union is connected with coiled tube arranged in annular clearance between housing inner surface and cylindrical barrel outer surface. Said tube is provided with branch pipes arranged at acute angle thereto along coiling path.

EFFECT: higher quality of water cleaning and decontamination.
