METHOD OF PURIFYING NATURAL WATER FROM ORGANIC WATER-SOLUBLE SUBSTANCES Russian patent published in 2020 - IPC C02F1/42 C02F1/28 B01J41/04 B01J49/00 B01J20/26 C02F101/30 C02F103/04

Abstract RU 2712538 C2

FIELD: chemistry.

SUBSTANCE: invention can be used for purification of natural water in electro-galvanic industry. Water is subjected to ion-exchange sorption by filtration through IA-1 anionite in chloride form, and then through finishing unit from mixture of cationite KU-2-8 and anionite AV-17-8. Simplified process of water purification by excluding stage of coagulation.

EFFECT: degree of purification from organic substances is 88,8–90,8 %.
