Description of the Related Art Generally, when an article is sequentially washed with several kinds of liquids, there is a problem of poor washing due to the carry-in of the washing liquid in the previous stage. For example, when cleaning a lens used for a camera or the like, the process is pre-cleaning → isopropyl alcohol (IPA) cleaning → chlorofluorocarbon cleaning → drying, but IPA of the previous tank is mixed in the final fluorocarbon tank. When the number of lenses to be processed increases and the concentration of IPA contained in the freon in the freon tank reaches 5% (hereinafter, the volume concentration of the mixed liquid with respect to the liquid mixture to be treated) is reached, it is a characteristic of the flon that it has quick drying property. Also, cleaning using a small surface tension is hindered, and cleaning failure occurs.

IPA was removed from the mixture. According to this method,
Water (tap water) 2a is introduced into the separation tank 1 from the distribution liquid introduction port 2, and CFC-IP is introduced from the liquid mixture introduction port 15 to be treated.
The A mixture 3a is introduced and mixed in the tank 1. Since IPA molecules are more hydrophilic than CFC molecules, IPA in CFC-IPA mixture is distributed to water. When the mixed solution is allowed to stand for a certain period of time, it is separated into a flon layer (lower layer) F and a water-IPA layer (upper layer) WI due to a difference in specific gravity. After that, the on-off valve 4 is opened to collect the chlorofluorocarbon from the bottom of the tank 1 and return it to the fluorocarbon tank.
