Water is the world’s most precious resource, so ensuring efficiency across the myriad industrial applications relying on water use is of supreme importance. With that in mind, NWPX Park is introducing its OilTrooper™ Oil-Water Separator, a cutting-edge system engineered for advanced contaminant removal in wastewater treatment. This innovative system ensures compliance with environmental regulations and is ideal for vehicle maintenance, wash rack facilities, fueling depots, vehicle repair facilities, and industrial areas. Installing our oil-water separator will reduce maintenance costs and ensure compliance with codes and regulations, while offering a safer approach to maintenance.
Leveraging NWPX’s patented Coalescing Media Pack (CMP) and a multi-compartment basin, the OilTrooper efficiently separates sediment, hydrocarbons, and oil from water, ensuring reliable performance and environmental compliance across commercial and industrial applications. The pre-engineered oil-water separator system is delivered with all internal components fully assembled, making installation quick, easy, and efficient.
PROTECTING RESOURCES, SAFEGUARDING QUALITY
OilTrooper delivers robust protection of water resources and optimal reliability for applications including auto shops, car washes, gas stations, parking lots, and industrial environments. Its standout CMP efficiently isolates even the finest solids and smallest oil droplets, maximizing contaminant removal and helping businesses meet regulatory demands while safeguarding water quality. Multi-chambered baffles guide wastewater through the unit, ensuring heavy sand settles while hydrocarbons rise to the surface, so only clean, compliant water exits the system.
Automatic, tank-mounted sensors continuously monitor separator capacity, ending the need for manual checks and minimizing maintenance overhead. When capacity is reached, a remote alarm alerts operators. Built-in spill control features, such as the oil stop valve and oil dam, deliver additional layers of environmental protection, making operation both safe and efficient.
HOW IT WORKS
As wastewater enters a sand-oil interceptor, it flows through a two-stage treatment process within the separator. In the first stage, the inflow hits a corrugated diffusion plate, which employs the Buffalo-Morse Principle to slow the velocity and create sinusoidal flow patterns that enable heavy solids to settle and oil to rise to the surface.
In the second stage, the wastewater passes through the CMP, where finer solids and smaller oil droplets are separated progressively. The CMP consists of closely spaced corrugated plates made of an oleophilic material that causes oil droplets to adhere to the plates due to buoyancy forces. The pattern of the plates induces a sinusoidal laminar flow that promotes droplet collision and coalesces smaller droplets into larger globules of oil that rise to the surface through openings in the coalescing plate pack. In addition, heavy solids are separated and settle to the basin bottom.
Before exiting the separator, wastewater hits an oil dam, which prevents any collected oil from entering the outlet piping. Finally, an oil stopping valve at the exit piping guarantees oil-free wastewater discharge.
ADAPTING TO DIFFERENT MATERIAL NEEDS
The OilTrooper system adapts easily to different site conditions with models available in high-strength precast concrete, steel, or fiberglass, and capacities ranging from 100 to 20,000 gallons. Installations can be above or below grade, and units are offered in both pedestrian and traffic-rated versions. A UL certified exterior NEMA 4X control panel and internal sensors provide real-time status updates and high oil level alerts, optimizing incident response and spill prevention.
Certified to comply with Uniform Plumbing Code (UPC) standards, OilTrooper is made in America and engineered for low maintenance performance, reducing costs and downtime for end users.
ENSURE COMPLIANCE WITH CONFIDENCE
The OilTrooper Oil-Water Separator empowers facilities to confidently meet stringent regulatory standards while protecting local water resources, reducing operational risk, and supporting long-term sustainability. By combining advanced contaminant removal with automated monitoring and versatile installation options, OilTrooper positions organizations for ongoing compliance, increased efficiency, and strong environmental stewardship in every application.
