METHOD OF COMPLEX WATER TREATMENT AND PLANT TO THIS END Russian patent published in 2011 - IPC C02F9/12 C02F1/28 C02F1/32 C02F1/36 C02F1/46 C02F1/48 C02F1/72 

FIELD: process engineering.

SUBSTANCE: invention relates to complex multi-stage treatment of industrial wastes or effluents. Proposed method comprises water diversion by pump 2, water cleaning of mechanical impurities in filter 3, water ultrasound treatment in cavitation unit 5, water separation in settler into clean water and sediment and further treatment by UV radiation in unit 10. Downstream of pump 2, 1 to 3% of water is bled for additional cavitation treatment. After said treatment, said water is fed to pump inlet. Prior to ultrasound treatment in cavitation unit 5, water is forced through gravel-sand filter 3 and saturated with iron ions in electrolyser 4 to produce yellow-grey solution with pH>6. After ultrasound cavitation, water is subjected to effects of light photons in light module 6 with energy of 60-70 ccal/mol and to that of magnetic field in magnetic module 7. Water purified by UV radiation in unit 10, it is subjected to additional magnetic field effects in magnetic module 11.

EFFECT: higher efficiency of water purification and higher water quality.
