FIELD: water supply and sewage systems, possibly purification and disinfection of drinking and sewage water with use of ozone. SUBSTANCE: apparatus includes housing provided with ceramic plate dividing housing by chamber for separating ozone-air mixture from water and contact chamber. The last has electrodes in the form of perforated horizontal partitions including upper cathode-plates and lower anode-plates. Plates are mutually joined along their perimeters by means of elastic dielectric gaskets. Housing is also provided with branch pipes for supplying initial water, feeding ozone and removing treated water and with pipeline for mutually joining both chambers. Branch pipe for supplying water has inlet unit with mixing chamber and narrowed nozzle with curvilinear helical grooves on its inner surface. Nozzle is joined with outlet adaptors forming T-piece with internal rifling on its end portion. Cycloidal conductors in the form of helix are arranged on inner surface of separation chamber. EFFECT: enhanced efficiency of ozonizing water. 4 dwg
