<p>PURPOSE:To minimize the exchange of members for purifying water and to enhance the water purifying capacity by connecting a gas-liq. contact tank, in which the water sent from a high water tank is brought into contact with air and purified, to a tank for sterilizing the water purified in the gas-liq. contact tank. CONSTITUTION:A gas-liq. contact tank 5, in which the water sent from a high water tank 1 is brought into contact with air and purified, is connected to a tank 8 for sterilizing the water purified in the tank 5, and the tank 8 is connected to a pipe 3 for supplying the water sterilized in the tank 8. A three-way valve 11 and a stop valve 15 are operated to supply the water in the high water tank 1 to the tank 5 from a pipe 14 through the water supply pipe 3. The water is purified in the tank 5 with the air cleaned in a liq. storage tank 25, passed through the tank 8, sterilized and sent to the water supply pipe 3 through the pipe 24, and the purified and sterilized water is delivered from a water tap. Accordingly, the members for the tanks 5 and 8, etc., have not to be exchanged, and only the liq. in the tank 25 is replaced.</p> |
