ABSTRACT:
An above ground oil and water separator including a pump to draw potentially contaminated water from a containment area, and to supply a flow of water to an enclosure. An enclosure inlet pipe takes water from the diaphragm pump into the enclosure. A first sub-enclosure is formed within the enclosure by a wall containing a plurality of coalescing spheres. The coalescing spheres are bagged within the first wall and can be removed through an external lid during cleaning and removal of coalesced oil. A heat source contained within an electrical panel heats water and supplies the heated water to the enclosure to prevent freezing within the enclosure.
