Solids & Oil Water Separation Systems

Oil and Solids Water Separation Unit

The Solids and Oil Water Separation Systems (SOWS) are horizontal gravity flow treatment systems designed to separate settleable solids, suspended solids, and free and dispersed oil.

New SOWS Systems Remove Both Free & Dispersed Oil AND Settable & Suspended Solids!

Introducing the new Best Available Technology (BAT) for the treatment of produced water and flow-back water. The Solids and Oil Water Separation Systems (SOWS) are horizontal gravity flow treatment systems designed to separate settleable solids, suspended solids, and free and dispersed oil.

This system is a significant improvement to the currently used CPI Separators which can only separate free oil and settleable solids – allowing a considerable amount of dispersed oil, suspended solids, and stable emulsions to pass through the system.

Applications:

  • Onshore and Offshore Drilling Operations
  • Oil Refineries
  • Produced Water
  • Waste Oil Processing Facilities

Benefits:

  • No moving parts
  • Low maintenance
  • Heavy duty carbon or stainless construction

The SOWS System has 5 stages of separation.

Solids Oil Water Separation

Solids Oil Water Separation


Stage 1, Inlet Area – The water mixture flows into the inlet quiescent area where the velocity of the water slows. The free oil (150 micron in size or greater) separates and rises to the surface where it is removed by a pipe skimmer.

Stage 2, Clarifier/Solids Intercept Section – The settleable solids flow downward and are captured in the clarifier/ solids intercept section.

Stage 3, Inclined Plate Section – The suspended solids and dispersed oil flow upward through the inclined plates section. Most of the suspended solids will slide down these plates into the hopper.

Stage 4, Separation Compartment – The remaining suspended solids and dispersed oil flow into the separation compartment where the coalescing plates remove 99% of the free oil droplets 30 micron or greater. This oil rises to the surface where an oil skimmer decants it to an oil storage tank. The coalescing plates then capture the remaining suspended solids.

Stage 5, Clean Water Compartment – The flow of water will go over the overflow weir into the clean water compartment where oil absorption polishing bags trap any trace oils before the water is discharged.
