APPARATUS FOR TREATING WATER BY OZONIZATION Russian patent published in 1995 - IPC

FIELD: water treatment equipment. SUBSTANCE: apparatus has bypass line connected with main pipeline for supplying water to consumer and two-position valve disposed adjacent to bypass line and main pipeline connection zone and adapted for bypassing of liquid from one pipeline to the other. Bypass line has mechanical filter, pressure relay, injector and additional liquid cleaning device, with all members being positioned in succession. Electric ozone generator is connected with injector through return valve and is associated with ac source through transformer. Pressure relay of bypass line is positioned between current source and transformer in electric circuit to provide switching of ozone generator only in case predetermined pressure difference is created in injector. Indicator-safety device positioned on high-voltage part of electric line may be formed as photosensitive diode. EFFECT: wider operational capabilities, increased efficiency and enhanced reliability in operation. 5 cl, 2 dwg
