Oily water separators

Oily water separators are used to separate the hydrocarbons from oily water coming from the bilge of a ship and deliver a cleaner effluent that can be discharged overboard according to IMO MEPC 107(49) regulation.

The Detegasa OWSAN series has been designed to assure an excellent performance while matching even the strictest conditions. It uses a coalescent filter in the first stage to separate the hydrocarbons by gravity. In the second stage there is an adsorption filter which acts as emulsion breaker.

The spare parts replacement and maintenance needs are minimum and the complete OWSAN series was granted the DNV Clean Design 5ppm type approval certificate to always be compliant with present and future regulations.
