METHOD OF WATER PURIFICATION Russian patent published in 2008 - IPC C02F1/34 C02F1/78 C02F103/04 C02F103/10 

FIELD: technological processes; chemistry.

SUBSTANCE: purified water is pumped through hydrodynamic radiator in cavitation mode, into which gas phase is supplied that contains ozone with concentration of more than 10 g/m³. Flow of gas-liquid mixture is supplied from hydrodynamic radiator into contact chamber upstream barring surface with further filtering of purified water from hard suspensions. In preferable variant of method implementation gas phase that consists of air and ozone or oxygen and ozone, is supplied into hydrodynamic radiator with compressor or by pulling vacuum in radiator. In order to increase time of purified liquid and gas interaction multiple pumping is carried out through hydrodynamic radiator.

EFFECT: increase of kinetics and extent of water purification; reduction of ozone consumption for water purification and reduction of water purification time.
