PURPOSE: A bath water treatment apparatus for a public bath is provided to enhance the pore washing efficiency of human body by increasing the sterilization of bath water and oxygen dissolution rate to re-provide the bath water into the bath. CONSTITUTION: A bath water treatment apparatus for public bath comprises a pressure tank(110), a bathtub water supply tube(130), a injection nozzle(140), an air supply part(160), and a bathtub water return pipe(180). The pressure tank contains a first partition board, a first conduction discharging pipe, and a first discharging pipe(137). The first partition board divides inner part into upper and lower direction and forms multiple chambers vertically. The first conduction discharging pipe is elongated to the lower part of the first partition board to guide discharging of stored water from the upper part of the first partition board to the lower part of the first partition board. The first discharging pipe discharges stored water into the lowest part of the chamber. The bathtub supply tube is extended from a main discharging pipe(11) of a bathtub(10) to the lowest chamber of the pressure tank. The injection nozzle is installed at the end of the bathtub water supplying pipe and sprays bathtub water to the highest part of the chamber. The oxygen supplying unit forms micro-bubbles at the bathtub water supplied by the pressure tank, and provides oxygen through the bathtub supplying pipe to form oxygen dissolved bathtub water. The bathtub water returning pipe is connected to the first discharging pipe to re-provide water ejected through the first discharging pipe. [Reference numerals] (165) Air pump |
