Abstract: The liquid separator is a molded or cast ceramic separation apparatus which causes centrifugal and centripetal-forces to be imparted on an incoming fluid stream which could be made up of two differing liquids such as oil and water or a fluid containing a solids/liquid mixture. The apparatus may be designed with modifications to be used in solids/liquids separations involving suspended solids such as sediments and bacteria-like organisms for separation from source water for use in ships' ballast water or similar types of separation applications. It can also be designed for the separation of two differing liquid phases such as oil and water. The separator may be used to remove large amounts of higher density water from an incoming process stream or it can be used for water cleanup applications. As well, it can be used where there are two liquids of varying density which require a separation of the two liquids involved.
