Get PriceOil water separators (OWS) are used for the separation of free and dispersed (nonemulsified) oil and settleable solids from water. Industrial Oil water separators are an effective tool to remove any type of oil lighter than water. Oil/water separators are a simple tool for treating water because gravity is the driving force for the separation.
Get PriceSeparation: The loosened debris and heavier contaminants will sink while the plastic films float.
