Oil And Water Separation


Oil Water Separation (OWS)

Separators are gravity separation devices designed by using Stokes Law to define the rise velocity of oil droplets based on their density and size. The design of the separator is based on the specific gravity difference between the hydrocarbon and the waste water because the difference is much smaller than the specific gravity difference between the suspended solids and water. Oil water separators’ purpose is to recover hydrocarbons that have segregated from emulsion in an gravity wastewater separation plant. Separators is sized by the flow rate versus the separation chamber’s effective surface area (or projected surface area in the case of a and coalescing and or parallel plate type separator). Therefore, the effectiveness of any oil water separator is affected by the flow rate. The slower the flow, the better the results. The OWS unit can be gravity or pump fed.
