Alfa Laval Inc. Compact Centrifugal Separator PreBilge

This compact centrifugal separator cleans bilge water feed before it enters the existing bilge water treatment system onboard. This ensures compliance with international oil pollution prevention regulations for safe discharge overboard. Cost-effective bilge water treatment An economical and reliable alternative to installing a new bilge water treatment system, Alfa Laval PreBilge is cost-effective solution for upgrading ship bilge water treatment systems that do not currently meet, or have high operating costs in order to meet, international performance standards. Using proven centrifugal separation technology, PreBilge oily water separator effectively cleans bilge water feed before it enters the existing bilge water treatment system, whether a gravitational coalescer or another type of system. This ensures that cleaned bilge water discharged overboard by the existing bilge water system meets international regulations for an oil-in-water content of between 5 and15 ppm – even when the ship is subject to unfavourable roll, pitch and heave motions at sea. Continuous oily bilge water pre-treatment Installed as a pre-treatment loop, PreBilge runs continuously, providing the existing system with clean, problem-free feed. There is no need for the crew to monitor treatment, investigate oil-in-water alarms or change filters. Compact, convenient installation Easy to install, this compact oily water separator can be positioned anywhere in the engine room. Pipe connections can be drawn as needed so proximity to the vessel’s bilge water tank is not required. Economical bilge water treatment Since the discharge and oil monitoring are handled by the existing system, PreBilge does not require its own type approval or affect the vessel’s IOPP certificate. It ensures regulatory compliance and reduces operating costs while maximizing uptime with minimal effort and no change to the vessel’s paperwork.
