We offer a complete line of high efficiency, stainless steel, above ground oil water separators that will remove 99.9% of free and dispersed non-emulsified oil and settleable solids from the waste stream.
Our staff of experienced engineers will provide you with an innovative, efficient, and cost effective solution to your oily waste water issues – just give us a call at 800-453-8639.
Innovative Oil & Water Separation
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
“Because of your separators and service, I was able to help one of my customers in a pinch and I have been able to grow my business from 3 employees to 26!”

“We have 3 SPT clarifier separators and they are all working great! I will definitely buy another one when we need one!Jason B.
“Our SPT separator is working perfectly! Last year, we tested the water downstream and the FOG was only 4 mg/l!Rudy U.

Water & Oil Separator Technology
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.

Oil Water Separator Case Studies
We showcase some of our case studies to help you understand our products, commitment and valuable service. Please review our oil water separator case studies below.
- Case Study – Locomotive Repair Facility Oil Water Separator Install – An engineer consulting with a railroad called with an application at a locomotive repair facility. Over time, lube oil and diesel fuel leaked from the locomotives into an inspection pit. Periodically, the oil along with sand and dirt collected in the pit was discharged into a retention pond. The oil was then skimmed from the surface of the pond and the water discharged to the sewer. [ Review Case Study ]
- Case Study of Oil Water Separator w/ Wash/Rinse Sewer Pre-Treat System This project was unique in that it was located in one of the strictest wastewater authorities in the state of North Carolina. [ Review Case Study ]
- Case Study of Truck Services Company Wash Bay – Wash/Rinse Closed Loop SystemThis major truck services company was constructing a new wash bay at their facility outside city sewer limits. [ Review Case Study ]
