Since the cleaning of the metal member is easier than the cleaning of the ceramic membrane filter, the water cleaning tank of the second cleaning tank and the third cleaning tank are configured as one cleaning tank to clean the resin member. Even if a part and the cleaning of the metal member are shared, the time required for the entire cleaning does not change.

る。As is apparent from the above description, according to the first aspect of the present invention, the regeneration of the ceramic membrane filter can be performed.
Since the cleaning is carried out batchwise using only the same cleaning tank, the entire apparatus can be made compact, and by using this cleaning tank as a closed tank, it is possible to eliminate harm caused by vaporization of chemicals. Further, according to the second aspect of the present invention, since the resin member is washed by adding a conductive salt in an aqueous solution, for example, in sodium chloride, Na + and Cl − become static electricity of the resin member. Is released, and the activated carbon fine particles can be easily separated from the resin, and can be washed by ordinary shower washing. Further, at this time, by applying the ultrasonic wave, the separation of the activated carbon from the resin can be further promoted.
