    Patent number: 5545316
    Abstract: Raw water containing organic chlorine compounds is supplied in an aeration tank, wherein the organic chlorine compounds contained in the raw water are transferred into air or gas. The gas obtained from the aeration tank is collected in a treatment solution of a decomposition-treatment tank.
