Abstract
An improved tunnel washer apparatus (20) is disclosed that includes a “ratio metric” water reuse system that features four water loops. The water loops include fresh water (24), reuse water (51), rinse water (49), and treated water (50). The tunnel washer (20) has five stages that include wet out (13), first wash zone (14), second wash zone (15), main rinse zone (16), and fine rinse/finishing zone (17). The water loops are designed to minimize the consumption of fresh water by blending the appropriate quantity of the four types of water. The blending formulation may vary based on the type of goods (for example linen) in the tunnel stage and the dynamic quality of each type of water.
