ABSTRACT:
The basin of a parts washer includes a spigot for showering parts to be washed with a solvent and a drain for draining contaminant entrained solvent. The drain conveys the contaminant entrained solvent into a removable tank containing a filtering fluid, such as water, of a higher density than the solvent. The solvent percolates upwardly through the filtering fluid into an upper tank. During percolation, the contaminants are segregated from the solvent and migrate to the bottom of the tank. In a variant parts washer, the solvent floats upon the filtering fluid in a common tank and the contaminants, in the form of a sludge, are segregated from freestanding filtering fluid and are collected as a moist, but not wet, sludge in a removable tank for disposal. When a water based solvent is used with any of the parts washers, only a single fluid is present; nevertheless heavy particulates and insoluble contaminants and debris will settle and migrate into the respective removable tank.
