Oil Water Separators: Achieving Discharge Compliance in Industrial Operations

What Is an Oil Water Separator?

An oil water separator is a critical piece of equipment for any industrial facility that generates oily wastewater. Vens Hydroluft designs and manufactures advanced oil water separators in Canada that use gravity separation, coalescence, and specialized media to efficiently separate oil from water, helping facilities meet stringent environmental discharge standards worldwide.

How Oil Water Separators Work

Oil water separators exploit the density difference between oil and water. Oily water enters the separator and flows through a series of baffles and plates that slow the flow velocity, allowing oil droplets to rise to the surface. Advanced designs use coalescing media to merge small oil droplets into larger ones that separate more easily. The separated oil is collected from the top while clean water exits from the bottom. For enhanced performance, pair separators with our coalescer oil water separator systems.

Integration with Oil Skimmers

Oil water separators work best as part of a multi-stage treatment system. Use belt oil skimmers or disc oil skimmers as a primary treatment to remove bulk floating oil, then polish the water through an oil water separator to achieve discharge-quality effluent. For high-volume applications, the Vens ORBIS Pro multi-disc skimmer provides the primary separation, with the oil water separator handling the final polishing stage. This combination achieves oil-in-water levels below 10 ppm in many applications.

Environmental Compliance and Global Standards

Environmental regulations worldwide require industrial facilities to treat oily wastewater before discharge. Vens Hydroluft oil water separators help customers meet EPA standards in North America, Environment Agency requirements in Europe, CPCB norms in India, and environmental standards across Asia, the Middle East, and beyond.
