An API oil-water separator is a device designed to separate oil and water mixtures, typically used in industrial and municipal settings. The design is based on the American Petroleum Institute (API) guidelines and primarily targets the removal of free oil and grease from wastewater.
Gravity Separation: The system relies on the difference in specific gravity between oil and water. Oil, being less dense, rises to the surface, allowing water to flow out.
Retention Time: API separators are designed to provide adequate retention time for effective separation, usually ranging from 30 minutes to several hours, depending on the application.
Baffle System: Baffles help direct flow and enhance the separation process by creating zones where oil can accumulate.
Skimmers: Floating skimmers remove accumulated oil from the surface.
