CPS B MK III + EBM 14x Bilge Water Separator Facet International has been a recognized world leader in filtration and separation for over 50 years, particularly for marine applications, refineries, petrochemical industries and aviation fuels. In 1978, Facet developed its first Coalescent Plates Separator (CPS); since then, Facet equipment has been at the forefront of oil-water separation of bilge water, complying with the IMO and Coast Guard resolutions. CPS 10B MKIII + EMB Bilge Water Separator Bilge water produced by new-generation ships — fast ferries, ferries, cruise vessels and warships — often contains "advanced" water-oil emulsions originating from the maintenance of turbines, engines and other shipboard mechanical systems. When this is the case, more sophisticated separation is required.
