PURPOSE:To completely perform both peeling and removal of rust and slime due to water hammering phenomena and agitating action and inhibition of generation of a foreign matter and sterilization due to action of ozone by discontinuously force-feeding ozone-contg. gas into the low part of the interval for washing a water supply pipe. CONSTITUTION:An interval for washing a water supply pipe P1 is set. Ozone- contg. gas is discontinuously force-fed at the pressure higher than water pressure in the low place in the interval for washing to this low place from an ozone force-feeding device A. Moreover the terminal of the interval for washing is opened to pass water and both ozone-contg. gas and water are discharged from this terminal. Both peeling and removal of rust and slime due to water hammering phenomena and agitating action and control of generation of a foreign matter and sterilization due to action of ozone are completely performed regardless of the structure of a water supply facility by this simple means. |
