PURPOSE:To remove iron or manganese component of well water thereby preventing generation of rust on pipes or the like by a method wherein a first stage processing machine for removing iron component and a second stage processing machine for activation are installed, and the first processing machine has a circulating pump which has a suction pipe leading to the bottom of a water receiving tank and a delivery pipe having an ozone adding pipe at a point midway therein. CONSTITUTION:A first stage processing machine 2 is provided to sterilize well water and to remove iron component, wherein a sealed tank 7 and circulating pump 8 are installed. Iron removal filter medium 9 is loaded on a perforated plate of the tank 7. A second stage processing machine is provided to activate water from which iron component has been removed at the first processing machine, wherein activating filter medium 14 is loaded in a sealed tank 13. Since low pressure is generated on the downstream side of an orifice of a delivery pipe 81 of the pump 8, ozone which has been continuously produced at an ozone generator 123 is drawn from an ozone suction pipe, in the form of jet, and is mixed with raw water to form ozone mixed water, thereby sterilizing miscellaneous bacteria, colon bacillus, virus, etc. |
