Abstract

PURPOSE: To enable the reuse of washing water, by separating used washing to a filtrate and a condensate containing substances by a regenerator, reusing the filtrate as washing water, and removing the contained substances from the condensate by a recovery device.
CONSTITUTION: Washing water, which was used in a washing vessel 1, is reserved in a holding tank 2 and introduced into a regenerator 4 by a pump 3. The regenerator, e.g., one involving a reverse osmosis membrane or the like mechanism, separates the fed washing water to a filtrate 5 and a condensate 6. The filtrate 5 is reserved in a tank 7, and carried with city water to washing vessel 1 for reuse. On the other hand, the condensate 6 is carried to a recovery device 9, where valuable substances are separated from the condensate 6. Thereafter, the residual 10 is concentrated and formed into sludge. The washing water to be used in the washing vessel 1 may be the one to be used in a photographic developer, for instance. In this case, silver and other various chemicals are recovered with high efficiency.
