How Does an Oil Coalescing Separator Work?

The M.W. Watermark Oil Coalescing Separator is designed to remove free non-emulsified oils, diesel, gasoline and fuels from a waste stream, resulting in an effluent quality of 10 mg/l or less of contaminants 20 microns and larger.

The Oil Coalescing Separator operation is based on closely spaced oil attracting media that promotes the impact and formation of larger oil particles. As the oil droplets increase in size their rise rate to the water surface also increases.

The influent water enters the separator through an inlet baffle that directs the water through the media bundle. The media expands the surface area of the separator giving the oil more room on which to combine.

As the oil droplets accumulate on the media and coalesce they develop into larger droplets that flow up the surface of the media, detach and rise to the water surface. Surface oil decants by gravity into a segregated oil reservoir where it can be removed from the tank.

Heavier solids will slide down the surface of the media into the sludge chamber at the bottom of the tank for periodic removal. Virtually oil free water travels under an oil reservoir baffle, over an adjustable weir and into a clean water effluent chamber. The water is then gravity discharged from this chamber.
