Oil Water Separators are specialised treatment systems that remove hydrocarbons, grease, and suspended solids from wash-down water to ensure compliance with environmental regulations. They operate using physical separation technologies such as coalescing plate packs, vertical tube coalescers, and hydrocyclones, which accelerate the natural separation of oil droplets and solids from water.

Under EPA guidelines and Australian Standard AS 1940 (The Storage and Handling of Flammable and Combustible Liquids), discharge water must contain less than 10 mg/L of total petroleum hydrocarbons (TPH) and be free from visible oil sheens before it can be legally discharged or reused.

Washbay HQ  | Oil Water Separators are purpose-built to exceed these requirements, integrating into our 100% above-ground modular wash bay systems. Unlike traditional in-ground systems that require extensive civil works, our modular design:

  • Ensures rapid deployment without council approval delays.

  • Provides full portability for temporary or leased sites.

  • Delivers lower maintenance and lifecycle costs through easy access and robust Australian-made construction.

  • Keeps clients compliant with EPA, WHS, and council standards across mining, transport, automotive, and government sectors.
