METHOD OF REAGENT WATER DESALTATION BY AMMONIUM HYDROCARBONATE WITH PRODUCTION OF COMPOUNDS SUBJECT TO FOLLOWING DECOMPOSITION Russian patent published in 2018 - IPC C02F5/02 C02F1/58 C01D7/12 C02F1/46 B01J19/08 C02F103/08 

FIELD: technological processes.

SUBSTANCE: invention can be used to produce marine and saline natural desalinated water. To carry out the process, sodium chloride is removed from the salt or sea water by conducting an exchange chemical reaction of sodium chloride with ammonium bicarbonate. Calculated amount of ammonium hydrogen carbonate is applied in dry form to water at a temperature of up to 18 °C followed by, after 10–60 minutes, the decomposition of the resulting compounds in the water, electro-impulse treatment in a sealed, electrically-pulsed, flow-through type reactor when the treated water is saturated with excess air oxygen. Final products of the reaction are then removed by degassing, settling and filtration.

EFFECT: invention provides a reduction in the capital and operating costs of the desalination process and the production of desalinated water at a predetermined level of sodium chloride therein.
