FIELD: filtration.
SUBSTANCE: invention is designed for demineralisation. The low-noise reverse osmosis demineralisation unit is comprised of a mechanical impurity filtration unit for the supplied sea water, a hydraulic drive and a reverse osmosis membrane installed in a frame body within a sound-insulating casing, a water cooling radiator and a fan supplying the air circulating inside the sound-insulating casing to the water cooling radiator. The inlet of the water cooling radiator is a sea water inlet, and the outlet of the water cooling radiator is connected with the inlet of the seawater mechanical impurity filtration unit.
EFFECT: increased reliability of the demineralisation unit.
