<p>The washing machine operation system uses a number of stages - preliminary flushing, two washing baths, and a number of flushing baths, re-using the mixt. from one stage in the preceding stage in the next sequence of operations. The used mixts. from all stages except the first are directed into tanks and there stored. They are returned to the washing machine at the start of specific preceding stages. The batches of mixt. from two stages can be returned for the preliminary flushing on the next sequence of operations, after which those used for preliminary flushing and the first washing stage are discharged to the drain, and those from all other stages are stored, for return at the start of preceding stages in the next sequence of operations. Fresh water is supplied only for the last two flushing baths.</p> |
