Facet International is the world leader in jet fuel handling, industrial coalescer separators, bilge water separator and other separation technology. Advanced filtration and separation products and systems for aviation, marine, petrochemical, water tretment, power genreation and general industrial markets.

Facet International has been a recognized world leader in
liquid/liquid separation for many years, particularly for refineries,
petrochemical industries and gas turbine fuels. This background in liquid/liquid separation led to Facet International's first oil water separator in 1968, which even then satisfied the IMO requirements which were to be announced in 1972.

Today, Facet is at the forefront of development for bilge water separators; our units can meet the latest IMO Res. A 393(X) without using any filter elements. We have found that many common systems using cartridges, or combinations of cartridges and gravity separators, require the equivalent of their initial capital cost each year in consumable cartridges. Because of this high cost, some ships do not replace cartridges at the specified intervals resulting in nonoperative units and marine pollution. Thus, Facet's bilge water separators can provide significant monetary savings and superior function.

DEVELOPMENT AND OPERATION
The patented coalescing plate separator packs used in our bilge water separator were developed during a seven year research and field trial program in the USA. The outcome of our research is an incredibly cost-effective system to separate oil from water to better than 15 ppm effluent, without the use of consumables.

The high efficiency of the coalescing plate packs is obtained by their use of both gravity separation and hydrodynamic coalescence. The plate shape, spacing and influent velocity have been combined to give complete removal of all oil particles of 20 microns and over (the best level achieved by a conventional gravity separator is total removal of particles of 60 microns and over). The plate shape promotes hydrodynamic collision of oil particles, and these collisions also mean many particles between 5 and 20 microns are captured by the plates. Our technical specialists will explain this principle in more detail if required.

The Facet unit is highly cost effective when seen as a total package. While its initial cost may be slightly more than conventional equipment, the Facet CPS-BV never requires replacement cartridges or other consumables.

CERTIFICATION
Certificates to IMO and MEPC.60 (33).

The integrated vertical helical rotary pump draws the water/oil mixture from the bilge and delivers it into the inlet equalization chamber. The flow is then split into two almost vertical upward
streams in which the gross oil is accelerated towards the oil collection area. The water, now only containing low concentration of oil, deflects towards the coalescing plate inlet section. In the
plates, oil particles down to 15 micron are fully removed from the water-phase and transferred to the oil collection area through weep holes. A scavenging/dry run prevention line is provided between the water outlet compartment and the suction side of the pump. The field-proven Facet level control device initiates automatic evacuation of separated oil to the slop tank.
