PROBLEM TO BE SOLVED: To provide a liquid treatment system capable of reducing the installation space of a hot water feeding device and a fine air bubble supplying device connected with a bathtub and reducing time and labor of installation.SOLUTION: The invention relates to the liquid treatment system 1 for treating liquid and supplying the liquid to the bathtub 2. The liquid treatment system 1 includes: the hot water feeding device 10 for performing heating treatment of the liquid the fine air bubble supplying device 20 for performing a gas pressure dissolving treatment for dissolving gas into the liquid by pressure in order to generate fine air bubbles and a liquid flow path 30 to which the hot water feeding device 10 and the fine air bubble supplying device 20 are connected respectively to guide treatment liquid to the bathtub 2 so that a simultaneous operation of supplying the liquids subjected to the heating treatment and the gas pressuring dissolving treatment to the bathtub 2 can be performed.COPYRIGHT: (C)2011,JPO&INPIT【課題】浴槽に接続される給湯装置と微細気泡供給装置の設置スペースの縮小化及び設置手間の低減を図る。【解決手段】液体を処理して浴槽(2)に供給する液体処理システム(1)を前提とする。液体処理システム(1)に、液体に加熱処理を行う給湯装置(10)と、微細気泡を発生させるために気体を液体中に加圧溶解させる気体加圧溶解処理を行う微細気泡供給装置(20)と、上記加熱処理及び気体加圧溶解処理が行われた液体が浴槽(2)に供給される同時運転が可能なように給湯装置(10)及び微細気泡供給装置(20)がそれぞれ接続されて浴槽(2)に処理液体を導く液体流路(30)とを設けた。【選択図】図1
