Proven to Reduce Haul-Away Costs Up to 90%

Proven Method for Fluid Reclamation

The PRAB Oil/Water Separator uses a proven coalescing method for gravity separation of oil from water to less than 15 ppm. This system is designed to meet and exceed all performance requirements of U.S. Coast Guard 46CFR162.050 and IMO Resolution A393 (X) of effluent discharge of 15 ppm free and mechanically dispersed oil in water.

Significantly Reduce Water Consumption

Oil/Water Mixture |


The oil/water mixture is pumped via a floating skimmer or is gravity fed into the separator. The separator which uses PRAB’s unique gravity/coalescence principle, removes free and mechanically dispersed oil from the influent. Separated oil is then automatically gravity discharged to a waste container. Clean water is discharged by gravity or through an optional discharge pump to the sewer, or back into the process.



This standard oil/water separator system is made of high quality carbon steel with epoxy coating (304 stainless steel units are also available). Oil weirs, as well as all piping, are PVC, galvanized steel, or stainless steel separator. Supply pump is offered in a variety of materials and is driven by an electric motor. An air operated double diaphragm (AOD) pump is also available.
