FIELD: process engineering.
SUBSTANCE: invention relates to water treatment. Initial water is forced through coarse filter 1 into precleaner 2. Therefrom, water flows into inlet tank 3 provided with level pickups 4. Therefrom, water is forced by electrically driven pump 5 into fine diaphragm filters 6. Filtered water is fed into mixing and cavitation unit comprising cavitation mixer 7 with mix ozone with water and hydrodynamic cavitation unit 8. Besides ozone-air mix is fed therein from ozonator 9. Then, treated water is fed into UV treatment unit 12 to be forced therefrom by pump 11 into intermediate tank 10. Then, water is cleaned at UV diaphragm filters 13. Prior to feeding water to consuming equipment, it is kept in accumulation tanks 16.
EFFECT: higher efficiency, reduced costs.
