What is the oil water separator?

An oil water separator (OWS) is a piece of equipment used to separate oil and water mixtures into their separate components. There are many different types of oil-water separator. Each has different oil separation capability and are used in different industries. Oil water separators are designed and selected after consideration of oil separation performance parameters and life cycle cost considerations. "Oil" can be taken to mean mineral, vegetable and animal oils, and the many different hydrocarbons.


Oil water separators can be designed to treat a variety of contaminants in water including free floating oil, emulsified oil, dissolved oil and suspended solids. Not all oil separator types are capable of separating all contaminants. The most common performance parameters considered are:

  • Oil droplet size (in the feed to the separator)

  • Oil density

  • Water viscosity (temperature)

  • Discharge water quality desired

  • Feed oil concentration and the range of oil concentrations likely

  • Feed oil water flow (daily and peak hourly)


The common used types of oil water separator have below items:

1. Florentine flask

2. API oil–water separator

3. Oily water separator (marine)

4. Gravity plate separator

5. Centrifugal oily water separator

6. Hydrocyclone oily water separator

7. Flotation

8. Nut shell filtration

9. Electrochemical

10. Downhole oil–water separation
