provider of oily water separators worldwide. The most commonly used oily water treatment systems use gravity to separate water from oil and solids. They are based on the principle of coalescence. Coalescers bind smaller and minuscule droplets of oil into oil droplets, which then rise faster in accordance with Stokes‘ law.

For over 45 years, RWO has been supplying future-proof solutions for marine water treatment – made in Germany. The product portfolio includes equipment for the treatment of drinking and process water as well as systems for pollution prevention such as oily water separators or sewage treatment plants.

More than 16000 ships have already been equip-ped with RWO’s oily water separators since RWO star ted its business in 1975. The OWS-COM sys-tem uses a combination of highly effective open porous coalescer with automatic backflushing, together with a second stage emulsion breaking oil and hy drocarbon polisher.

The RWO SKIT aquaclean "S" ows utilises a completely new flow control principle. The latest scientific discoveries on oil-in-water dispersion, homogenous flow mechanisms and

RWO Oily Water Separator (OWS-COM) complies with the latest IMO Resolution MEPC.107(49) using the combination of the highly effective open permeable original RWO Coalescer together with a second stage emulsion breaking oil and hydrocarbon polisher.

RWO’s classic: Oily Water Separators Your key benefits > Most economical: second stage is bypassed whenever possible > Easy to install and maintain > Safest: Oil Monitoring device always checks effluent > Suction type: preserves pump from attrition > Most compact: suitable for newbuilds and retrofit > Improved hydrodynamics for longer ...

More than 20,000 ships have already been equipped with RWO’s oily water separators since 1975. Like previous RWO Oily Water Separators, the OWS-COM uses a combination of a highly effective open porous coalescer with automatic backflushing, together with a second stage emulsion breaking oil and hydrocarbon polisher.

RWO’s classic: Oily Water Separators Automatic bypass ensures economical operation To extend the operating life of the demul- sifier, an automatic bypass is fitted to the separating system. The oil content monitor periodically checks the water quality of the first stage separator. If below the set max. value, the demulsifier is bypassed.

More than 14,000 ships have already been equipped with RWO’s oily water separators since RWO started its business in 1975. As its predecessors the OWS-COM uses a combination of highly effective open porous coalescer with automatic backflushing, together with a second stage emulsion breaking oil and hydrocarbon polisher.

The OWS is intended to be used for the separation of bilge water consisting of dispersed oil- water mixtures and emulsified hydrocarbons in accordance with IMO requirements. Important
