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 Vacuum Sewage Treatment Plants (VTP) for marine applications are designed for the treatment of black water (coming from W.C., urinals and hospital) and grey water (sinks, showers, laundry and galley) generated onboard ships. This treatment includes the purification and later disinfection of water in order to achieve a quality effluent meeting all necessary requirements. These plants treat sewage biologically, meaning they are of the active sludge, prolonged aeration, aerobic type.

Facet VTP plants are built in a single steel module to ease transportation and onboard installation. Inside this module there are three specially designed chambers for aeration, settling and disinfection. These chambers are oriented in such a way as to guarantee correct operation and avoid sludge generation. Each chamber has been provided with an access and inspection register.

Air diffusers are located in the aeration chamber, and they produce both oxygenation and shaking of the liquid to be treated. The unique design of the settling chamber causes the active sludge inside it to separate from the effluent and automatically recirculate to the aeration chamber. Both, the clarified liquid and grey waters reach the disinfection chamber where a chlorine solution is dispensed and metered in order to remove fecal coliform bacteria. Once disinfection has taken place, the effluent is automatically or manually discharged overboard or into a containment vessel.

What makes the VTP system unique is its built-in vacuum system that transports black waters along the piping system to the treatment plant. The vacuum in the circuit is achieved automatically with the ejector and circulating pump.

Facet Sewage Treatment Plants VTP Series meet Marpol Annex IV Requirements, 8(1)(b) and 9.1.1 Regulations, as well as IMO Resolution MEPC-2(VI), CE Standards 96/98/EC and 98/85/EC; they do not generate sludge that should be later discharged. The plants are supplied completely assembled and tested so that their installation onboard is very quick.
