<p><P>PROBLEM TO BE SOLVED: To provide a method of flushing the piping of a circulating bathtub capable of mainly physically effectively removing biofilm allowing Legionella group bacterium to inhabit therein. <P>SOLUTION: Deposit formed mainly of biological slimes generated in the circulation piping of the circulating bathtub is fed by feeding air into the piping and intermittently filling the mixed fluid of ice and water into the air flow to flush the piping so as to remove the deposit from the piping. Also, a supply device capable of intermittently feeding the mixed fluid of ice and water into the air flow is connected to one end of the piping to be flushed. In addition, a discharge device sucking/discharging air or air and the mixed fluid is connected to the end of the piping to flush the inside of the piping. <P>COPYRIGHT: (C)2004,JPO&NCIPI</p> |
