DEVICE FOR CLEANING AND DECONTAMINATION OF WATER BY HIGH-VOLTAGE ELECTRICAL DISCHARGES Russian patent published in 2000 - IPC

FIELD: devices for treatment of water for drinking water and technical water supply systems; cleaning of sewage from toxic admixtures, activation and decontamination of water; water treatment systems. SUBSTANCE: device has housing with high-voltage electrode made in form of grid and grounded electrode made in form of perforated partition inside it. Water supply branch pipe is located in area of grounded electrode and oxygen- containing gas supply branch pipe is located in upper portion of device. Contact aerator is mounted in device below grounded electrode; cavity located under contact aerator is connected with upper portion of device by means of air line; high-voltage electrode is mounted in upper portion of device. Fan mounted inside air duct provides for circulation of circulation of ozone-and-air mixture. Ozone-containing gas discharge branch pipe is connected with jet pump where water is subjected to repeated ozone-treatment. EFFECT: enhanced efficiency of cleaning and decontamination of water; reduced power requirements; enhanced operational reliability. 2 dwg
