Oil-Water Separators
Engineered for Reliability, Marine Compliance & IMO Performance
Our oil-water separators are designed to help you manage oil-contaminated water across a wide range of critical environments—from industrial process water and stormwater runoff to marine vessels, offshore substations, and shipboard systems.
Whether you require a bilge water separator, an IMO approved bilge separator, or a complete oily water separator marine system, Facet delivers engineered solutions that ensure reliable operation and regulatory compliance.
Easy to install and adaptable for both upgrades and new projects, these systems provide consistent, low-maintenance performance so you can keep operations running smoothly and in full compliance with EPA, EU, and IMO discharge standards.
Powered by MPak® Technology
Every Facet Oily-Water Separator features MPak® coalescing plates, our advanced solution for efficient oil and solids removal.
MPak® technology is engineered to separate oil and solids from water using the natural differences in their specific gravities.
Made from a special oleophilic material, these plates encourage oil droplets to stick together and rise to the surface, while solids collect below for easy removal. This proven coalescing process makes MPak® ideal for:
- Bilge water separator systems
- Offshore and floating infrastructure
- Industrial wastewater treatment
- Stormwater treatment vaults
- Oil & gas discharge compliance
