FIELD: treatment plant.
SUBSTANCE: invention relates to membrane engineering and can be used for purification of waste water by reverse osmosis. Proposed device comprises reverse osmosis device, vessel-balancing tank purified water, pump, magnetic valves, shutoff valves, expansion tank, mesh filter, reverse osmosis device of first stage settler reverse osmosis, concentrate storage container with submersible pump, reverse osmosis device of second stage, reverse osmosis membrane roll type with an open channel in which there is no turbulizing grid, and reverse osmosis device of second stage is made with possibility of circulation in it concentrate.
EFFECT: technical result is cleaning waste water without afterpurification to filtrate outlet (pure water) up to 99 % of initial, absence of reactant treatment of water, automated operation without constant maintenance personnel.
