APPARATUS FOR HYDRODYNAMIC TREATMENT OF WASTE WATER Russian patent published in 2012 - IPC C02F1/64 C02F1/74 

FIELD: chemistry.

SUBSTANCE: water saturated with atmospheric air is fed by a pump 1 into the confusor 3 of the first unit of a cavitation device through an adjustment device 2. The turbulent micro-bubble stream of water from the confusor 3 is fed into a cylindrical chamber 4, into which gas from a source 12 is fed. The treated stream of water from the cylindrical chamber 4 is fed into the diffuser 5 of the first unit of the cavitation device. The stream of water from the diffuser 5 is fed through the adjustment device 6 into the confuser 7 of the second unit of the cavitation device. The turbulent micro-bubble stream of water from the confusor 7 is fed into the cylindrical chamber 8 of the second unit of the cavitation device, into which gas from the source 12 is fed. The treated stream of water from the cylindrical chamber 8 is fed into the diffuser 9 of the second unit of the cavitation device. The treated water is fed to the consumer.

EFFECT: invention protects the environment from contamination with poisonous chemicals.
