Abstract:

A compact, self-contained skimming system for removing waste material from aqueous cleaning solutions used in parts washers. A single tank contains a sloped floor, two compartments separated by a baffle, and an opening between a bottom edge of the baffle and the floor. Waste liquid collects in the first stage compartment, where gravity initially separates water and coarse debris from the waste material containing oil and grease, some water, and fine debris. A partially immersed rotating skimmer further adsorbs the waste material. A waste collection system transfers the waste material to the second stage compartment, where gravity further separates the fine debris and additional water from the oil and grease. The oil and grease flow through a waste drainage system out of the second stage compartment. The fine debris and water flow along the downwardly sloping floor, through the opening at the bottom of the baffle back into the first stage compartment.
