METHOD AND APPARATUS FOR PREPARATION OF PRESSURIZED WATER

摘要

PROBLEM TO BE SOLVED: To prepare pressurized water by neither using a gas-liquid separating tank nor generating macroair. SOLUTION: This apparatus has a gas dissolving apparatus 1 having a pressurizing part 2 and an air suction type gas feed part 3; a water feed pipe 4 and a water drainage pipe 5 which are connected to the gas dissolving apparatus 1; a gas suction pipe 6 connected to the air suction type gas feed part 3; a water feed amount measuring means 7 for measuring a water feed amount of raw water of the water feed pipe 4; a pressure meter 8 for measuring a pressure of pressurized water to be drained from the water drainage pipe 5; and an air suction adjusting valve 9 which is disposed in the gas suction pipe 6 and can adjust a gas suction amount according to the water feed amount and the pressure of the pressurized water.
