description PURPOSE:To easily remove the suspended matter accumulated on filter media so that secondary chemical pollution is prevented and carcinogens are decomposed away by bringing ozone into contact with the treated water passing a sterilizing lamp housing tank to flocculate the particles of the suspended matter in the water, then adsorbing the suspended matter flocculated after passing the filter media in a filter medium housing tank by the filter media. CONSTITUTION:The ozone generated from the sterilizing lamp 2 or the ozone sent from a noiseless discharge type ozonizer comes into contact with the treated water passing the sterilizing lamp housing tank 1 to flocculate the particles of the suspended matter in the water. The pathogenic bacteria in the water are sterilized and the org. matter is photooxidation-decomposed, by which COD, BOD and odorous components are decreased. The treated water thereafter passes the filter media 8 of the filter medium housing tank 6 where the flocculated and suspended matter is adsorbed by the filter media 8. The filter media 8 is suspended in the water in the filter medium housing tank 6 and is agitated in the case of back washing the filter media 8. The dust, etc., sticking to the filter media are thereby separated and easily removed.
