METHOD OF SEAWATER DESALINATION USING SEMICONDUCTOR THERMOELECTRIC COOLING DEVICE WITH ULTRAVIOLET RADIATION AT ARTIFICIAL REDUCTION OF ATMOSPHERIC PRESSURE Russian patent published in 2019 - IPC C02F5/00 C02F1/04 C02F1/08 B01D1/22 B01D5/00 C02F103/08 

FIELD: water treatment.

SUBSTANCE: invention can be used in sea water desalination. Method is carried out in a desalination plant with a semiconductor thermoelectric cooling device, wherein the method includes bringing sea water to boiling followed by condensation of water vapour on the surface of the cooling device and removal of fresh water. Sea water is brought to boiling at ambient temperature by means of artificial reduction of atmospheric pressure, using a desalination plant consisting of two sealed chambers (2, 3) with reservoirs for sea and fresh water, made with mirror walls, with creation of low pressure in chambers alternately due to air pumping (18) by pump (1) through air solenoid valves (7, 11). For cooling water vapour there is used semiconductor thermoelectric cooling device (21) with ultraviolet radiation.

EFFECT: method ensures reduction of power consumption and environmental safety of the desalination plant operation, reduction of boiling temperature of sea water to ambient temperature with simultaneous disinfection of water with ultraviolet radiation.
