Abstract 

Technological scheme of cavitational water refinement is described that includes fourth stages: mechanical water refinement (first stage), water treatment by adsorbers (second stage), cavitational water treatment with gas bubbling (third stage) and fourth stage water is supplied to adsorbers again for microbial cells separation from the water and for products removal after cells destruction under cavitation treatment. The effectiveness of water purification is 95-99% that depends of initial amounts of microbes in the water system.
