METHOD FOR REDUCING ENERGY SUPPLY OF MEBRANE-MODULAR WATER TREATMENT SYSTEM DURING ORIGINAL SEAWATER DESALINATION Russian patent published in 2021 - IPC C02F1/44 B01D61/12 B01D61/08 B01D61/06 

FIELD: water engineering.

SUBSTANCE: invention relates to the field of water engineering and to a method for producing water-treatment systems using the reverse osmosis desalination of sea and groundwater for small recreational facilities. The method for reducing the energy supply of a membrane-modular water-treatment system during the original seawater desalination comprises a reverse osmosis process of separating the seawater in a membrane water filtration unit into a high-concentration solution and a low-concentration solution which is directed through the stabilization unit to the consumer, the first-stage pump is launched at the launching stage at the expense of the electric motor, after launching the membrane unit, the motor is switched off from it and its work from the mechanical energy converter and the speed converter continues, with the high-concentration solution being supplied to a unit for the utilization of the high-concentration solution by discharging said solution into the deep layers of seawater; evaporation by using geothermal and solar energy; utilization of the salts obtained in construction as additives to concrete, in road construction as anticold coatings.

EFFECT: technical result consists in energy recovery in a production circuit on the basis of a reverse osmosis system.
