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.

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

Bi-directional corrugation increases surface area for superior separation while reducing the overall system footprint

Multiple plate spacing configurations and sizes available, allowing for flexible installation and customized design

Engineered for single-stage operation, MPak® simplifies system design while improving reliability—critical for marine oil water separator performance in harsh environments.

Plates can be cleaned without removal, minimizing downtime and maintenance effort

Constructed for long life, requiring no consumable filters or replacement parts

No matter your application or existing setup, we can design and manufacture MPak® solutions to fit your exact requirements. Contact us for a custom quote—we’ll work with you to create a solution that meets your flow, footprint, and performance needs.

Certified Performance Meeting Worldwide Environmental Standards

Our Oil-Water Separators have achieved EN-858 Class 1 Certification, demonstrating proven performance that meets the most stringent international standards including EU, EPA, and IMO requirements for oil-water separation. This certification is backed by rigorous independent testing that validates our MPak® technology delivers Class 1 performance, the highest tier available for coalescing separator systems globally.

MPak® coalescing plates can be retrofitted into virtually any existing oil-water separator system.
