ABSTRACT:
A waste-oil cleaning apparatus includes a processing tank for holding waste-oil, and arranged such that non-oil liquids in the waste-oil settle in the base of the tank. A conduit and valve arrangement is provided for withdrawing the settled non-oil liquids from the base of the tank. The apparatus also incorporates an oil cleaning unit including a pump, a mesh filter and a centrifuge. Waste oil in the tank is cleaned by pumping oil out of the tank and passing the oil sequentially through the mesh filter and the centrifuge after the settled non-oil liquids are withdrawn from the base of the tank.
