METHOD OF WATER CLEANING AND DECONTAMINATION Russian patent published in 2013 - IPC C02F1/52 C02F1/76 C02F9/02 C02F9/04 B03D3/02 B01D21/02 G05D27/00 C01B11/06 C25B1/14 

FIELD: process engineering.

SUBSTANCE: set of intention relates to water treatment and may be used in various industries. First, chlorinated coagulant is subjected to electrochemical treatment at membrane or diaphragm electrolysis unit 3 with insoluble electrodes to produce high-basic coagulant and gaseous chlorine. High-basic coagulant is mixed with water flow fed into settler 4 for coagulation and flocculation of undissolved suspensions and mechanical impurities. Gaseous chlorine withdrawn from electrolysis unit is fed into chlorine proportioner 6 to make bleaching water. Said water is fed for decontamination in cleaned water flow between said settler 4 and mechanical filter 8.

EFFECT: higher quality of purification.
