Oily Water Separation Systems - Marine & Ship Spare Parts ⬝ Supplied Worldwide

PureBilge

Alfa Laval PureBilge is a fully automated centrifugal oily water separation system that treats bilge water onboard. It handles large volumes and can reduce oil content to below 5 ppm – well below the IMO’s 15 ppm requirement.

Reliable bilge water separation, compliance-ready by design

Compact and modular. Easy to install. Saves time, space, and cost.
Efficient single-stage process, less holding tank volume and more payload capacity.
Low maintenance - fully automated, no chemicals, no disposable filters and minimal waste.
Secure overboard discharge - password-protected, only authorized crew can release water overboard.

Alfa Laval PureBilge uses high-speed centrifugal separation technology to clean oily water/bilge. The patented XLrator spiral inlet prevents oil droplets from splitting and forming emulsions, improving separation efficiency. The system is also available in a smaller version – PureBilge Compact. PureBilge Compact is built for vessels with lower treatment needs. It fits both new builds and retrofits. No chemicals. No filters. Designed for 24/7 unmanned operation.

Bilge water treatment for real-life conditions

Bilge water isn’t just oil, water, and particles.
It’s a complex chemical mix that makes meeting discharge limits – especially 5 ppm – challenging in real-world conditions. Alfa Laval PureBilge is built to handle that complexity. It’s an oily water separator (OWS) that performs reliably, not just in tests, but out at sea.

How PureBilge Works

PureBilge is a fully automated bilge water treatment system that combines pumping, preheating, and centrifugal separation to meet IMO discharge limits – even down to 5 ppm. Oily water is filtered and heated before entering the separator, where it spins at 8,000 rpm to remove oil, emulsions, and solids. Clean water is discharged only if oil content is below the set limit; otherwise, it’s recirculated. The system features the patented XLrator inlet for efficient flow and now includes the EPC 70 control cabinet, offering advanced process control and built-in cybersecurity protection.

Features that set PureBilge apart

Fully automated

PureBilge integrates pumping, preheating, and high-speed centrifugal separation with full process control and monitoring—ensuring reliable, hands-free operation.

Compact and modular design

Its space-saving footprint and modular setup simplify installation and integration, reducing time and cost during setup and maintenance.

XLrator spiral inlet

The patented XLrator spiral inlet and 6,000 G centrifugal force enable uninterrupted, single-stage operation with superior oil-water separation—even under tough conditions.

Low OPEX

No chemicals, no disposable filters, minimal waste disposal, and automated control all contribute to significantly reduced maintenance and operating expenses.

Robust performance in harsh conditions

PureBilge maintains stable operation regardless of sea heave, oil shocks, or trace solids loading—ensuring consistent compliance and performance.

Secure discharge control

A password-protected switch ensures only authorized personnel can initiate overboard discharge, supporting strict environmental compliance and operational accountability.
