CPI Oil Water Separator

CPI (corrugated plate interceptor) separators are used predominantly to separate free oil from wastewater/effluent. CPI unit is deployed at the primary stage of wastewater treatment wherein plate packs are used as the main separation device. The plate packs are designed with specific spacing and alignment to enable solids to settle and fall to the bottom while allowing oil drops to rise and coalesce. A CPI is also equipped with a secondary coalescer screen. This oleophilic coalescer traps oil particles down to 20 microns. Small particles coalesce into large globules and rise to the surface. Oil is skimmed using a suitable skimmer. Sludge at the bottom is removed by either gravity force or by a sludge removal pump.

CPI Oil Water Separator Overview

Our CPI oil water separator works on the principle of gravity difference between oil and water. The CPI is a stationary wastewater treatment tank filled with oily water. Internal baffles and chambers enhance the oil-water separation process. Solid waste accumulates in CPI, water is discharged by gravity, and floating oil is skimmed using a suitable skimmer.
