2. API oil–water separator - Wikipedia

   en.wikipedia.org/wiki/API_oil–water_separator

   A typical gravimetric API separator. An API oil–water separator is a device designed to separate gross amounts of oil and suspended solids from industrial wastewater produced at oil refineries, petrochemical plants, chemical plants, natural gas processing plants and other industrial oily water sources.

3. Hydrodynamic separator - Wikipedia

   en.wikipedia.org/wiki/Hydrodynamic_separator

   In civil engineering (specifically hydraulic engineering), a hydrodynamic separator (HDS) is a stormwater management device that uses cyclonic separation to control water pollution. They are designed as flow-through structures with a settling or separation unit to remove sediment and other pollutants. [ 1 ]

4. Centrifugal water–oil separator - Wikipedia

   en.wikipedia.org/wiki/Centrifugal_water–oil...

   In a centrifugal oil and water separator, the force of gravity is one-thousand [citation needed] times greater that of the coalescing plate pack separator or the petrol interceptor, so the separation is much greater. Not only is the force of separation greater, but there are fewer working parts so maintenance is much easier and cheaper.

5. Oil–water separator - Wikipedia

   en.wikipedia.org/wiki/Oil–water_separator

   Centrifuge oily water separator. A centrifugal water–oil separator, centrifugal oil–water separator or centrifugal liquid–liquid separator is a device designed to separate oil and water by centrifugation. It generally contains a cylindrical container that rotates inside a larger stationary container.

6. Urban runoff - Wikipedia

   en.wikipedia.org/wiki/Urban_runoff

   Oil slick created by runoff A percolation trench allows infiltration of stormwater through permeable soils into the groundwater aquifer. An oil-grit separator is designed to capture settleable solids, oil and grease, debris and floatables in runoff from roads and parking lots. Excessive stream bank erosion may cause flooding and property damage.

7. Separator (oil production) - Wikipedia

   en.wikipedia.org/wiki/Separator_(oil_production)

   A heated-water bath is probably the most effective method of removing foam bubbles from foaming crude oil. A heated-water bath is not practical in most oil and gas separators, but heat can be added to the oil by direct or indirect fired heaters and/or heat exchangers, or heated free-water knockouts or emulsion treaters can be used to obtain a ...
