ABSTRACT:
Solid contaminants are removed from tramp oil containing aqueous emulsions, the emulsions are separated into reusable constituents and the separated aqueous liquid is recycled. Apparatus and method are provided especially for reclaiming solvents, washing solutions, lubricating oil, cutting oil and the like from installations for cleaning, quenching or washing oil coated stampings, parts, and the like. Dirt, grit, scale and the like contaminants are filtered out from used industrial cleaning solutions, the liquid components are coalesced into reusable constituents and the aqueous component is continuously recycled for re-use without loss of dissolved chemicals or consumption of energy for heating or cooling. The apparatus is compact, self-contained with a filter, an electric motor driven pump, and valved piping to be easily mounted adjacent and connected to industrial equipment without disturbing the equipment, operates with a minimum amount of energy and is serviced without interruption of the operation of the equipment.
