ABSTRACT:
The efficiency of a multi-stage rinsing operation is improved by routing a substantial portion or all of the overflow rinse liquor from the collecting tank of one stage directly to the spray rinse of the next succeeding stage along with rinse liquor from said succeeding stage. Improved cleanliness of the rinse liquor at each rinse stage is thereby attained while maintaining a self-regulating rinse system.
