Oily Water Separator (OWS) is a piece of special equipment for the shipping or marine industry used to separate the oil and water mixture into their separate components. This page refers exclusively to oily water separators on seagoing ships. They are found on ships, where they are used to separate oil from oily effluents, such as wastewater, before draining it into the environment.
Bilgewater is an almost inevitable product of ship operations. Oil leaks from working machines such as diesel generators, air compressors, and the main drive engine.
Produces clear crystalline water (15 / 5ppm). OWE effectively removes contaminants from water instead of trying to remove them. Our simple solution processes water in two consecutive steps:
Step 1: Merge + Pony
Of course, merging and settling are interrelated and are key to the processing of dirty water. But merging filters are well known for their fast clogging and reduced performance. So, in step 1, we combine our OWE with a large mattress to settle only the "easy-to-catch" floating oil. Hard to trick and easy to clean.
Step 2: Two state changes from effluent to steam to clear water
The final purification is based on two successive phase transitions: oily water to steam to distilled water. The purpose of this step is to decompose a thin, stable emulsion containing dissolved oils or contaminants. These effluents are generally difficult to settle. This is the hard part.
OWE uses heat recovery from the main engine or any other heat dissipation to boil water from the effluent at negative pressure. The vapor then condenses into clear distilled water.
