PureBilge oily water treatment system 

PureBilge is a fully automated centrifugal bilge water treatment system that cleans oily wastewater onboard vessels at sea. By effectively removing marine oil pollution, it makes bilge water safe for discharge overboard.

This reliable single-stage high-speed centrifugal separation system effectively cleans large bilge water volumes at sea as well as ashore without the use of chemicals, adsorption filter or membranes.

Cleaning efficiency

PureBilge generally achieves an oil-in-water content of less than 5 ppm. Performance has been proven under real-life operating conditions and is unaffected by sea heave, oil shocks or high solids loading.

Superior separation performance

PureBilge features a patented XLrator disc inlet, which gently accelerates the bilge water as it enters the separator bowl. This prevents the splitting of oil droplets and the formation of additional emulsions, which gives PureBilge a substantial edge over other centrifugal separation systems.

Certified and cost-effective

Certified according to IMO resolutions, MEPC.107 (49) and US Coast Guard document 46 CFR 106.50, PureBilge is designed for unmanned 24/7 operation.

No man-hours are required for operation or supervision. There’s also no reject to pump ashore and no need to transport land wastes such as filter elements, coalescence elements, active carbon, or flocculation deposits. This contributes to reduced operating costs.

Easy to install in any engine room

Designed for plug-and-play installation, PureBilge is a compact and factory-tested separator module that is easy to install in any engine room. Continuous operation means that there is no need for large bilge water holding tanks, which frees up space and increases payload capacity.

Fully automated monitoring and control

The new EPC 60 Bilge process controller is an easy-to operate, computer-based Alfa Laval process controller. It facilitates advanced fully automated monitoring and control of PureBilge functions by displaying in clear text process parameters, alarms and other data.
