Oily Water Separators

oily waters

The main purpose of the oily water separator is 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 OWSAN series uses a coalescent filter in the first stage to separate the hydrocarbons by gravity and an adsorption filter in the second stage acting as emulsion breaker.

Detegasa’s Oily Water Separator (OWSAN series) has been designed to assure an excellent performance under the strictest conditions.

Furthermore, spare parts replacement and maintenance needs are minimum.
Renowned clients like DSME, Hyundai HI, Samsung and Total Offshore have experienced the engineering capabilities of Detegasa for special offshore projects, with different hazardous zone requirements and specific logistic needs.
Always aiming to provide solutions that comply with present and future regulations, Detegasa has been granted the DNV Clean Design 5ppm type approval certificate for the complete OWSAN series.

The OWSAN Oily Water Separator will more than meet the strictest regulations requirements, as demonstrated in the final tests, where a reduction well below 2ppm was obtained
