  • Method for purification and disinfection of water
    Patent number: 6802981
    Abstract: A novel system and method for purification and disinfection of water containing contaminates is provided. The system includes an aeration column, a first intermediate tank, a first mechanical filter, an electric discharge device, a second intermediate tank, a second mechanical filter and a sorption filter. The water is firstly aerated by continuous mixing the water with air and ozone-air mixture. The water obtained after the aeration is treated with coagulant materials in a medium of the ozone-air mixture. Further, the water is filtered from coagulated particles. Thereafter, the water is treated by electric discharges in an air medium. The water is then treated again with coagulant materials. Finally, the water is filtered from remaining contaminates.
