Washbay - Above Ground Oil Water Separators

Oil water separators use parallel corrugated plates to cause the oil droplets in the water to increase in size, thereby speeding the gravity separation process. We enhance this process with our innovated UNIPACK cross-fluted media design with an internal structure of interconnecting channels with multiple crossing points between adjacent plates.

Coalescing of the oil droplets takes place in three steps:

• Corrugated plates intercept oil droplets as the oil/water mixture flows through the separator.
• New droplets coalesce with retained droplets, to make larger droplets.
• Enlarged oil droplets separate from the water and rise to the surface

• Heavy-duty stainless steel construction
• Conforms to the guidelines of API 421
• Unique UNIPACK cross fluted media design – reduces size of separator
• 99% oil and solids removal
• Range of options and sizes available to fit your application

• Low maintenance and operational costs
• Easy cleaning through removable vapor tight covers
• No moving parts or power consumption
• No chemicals, absorbent or filter cartridges to remove, replace or dispose of
• Compact size

The most common approach to the design of oil water separators is to configure parallel corrugated plates that cause the oil droplets to increase in size, thereby speeding the gravity separation process. We use a unique Unipack cross fluted design with an internal structure of interconnecting channels having many crossing points between adjacent plates. This produces enhanced efficiencies in significantly smaller units. Our Unipack construction requires a unit with only 5000 gallons capacity to produce the same yield of a traditional separator unit with 15,000 gallon capacity at a flow rate of 500 gallons per minute.
