ABSTRACT:
An oil-water separator system and method to separate contaminated oil and water into clean water and free coalesced oil for collection and removal. The system includes a process tank for the oil and water, a pump to pump the oil and water through first and second stage oil-coalescing filters and through a full depth, fibrous filter under back pressure to provide filtered clean water of selected purity; typically, less than 20 ppm. The coalesced and filtered oil-water is returned and recycled to the process tank wherein a free coalescing oil layer forms on the surface, which free coalesced oil is removed by a belt skimmer for collection and removal.
