Potential - Tilted Plate Interceptor (TPI) Oil Water Separator - Brochure

TPI (Tilted plate interceptor) separators, including the TPI oil water separator, are utilized predominantly to separate free oil from effluent. TPI units are deployed at the primary stage of wastewater treatment, wherein plate packs serve as the main separation device. These 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 TPI is also equipped with a secondary coalescer screen, which effectively traps oil particles down to 20 microns. Small particles coalesce into large globules and rise to the surface, where oil is skimmed using a suitable skimmer. Sludge at the bottom is removed by either gravity force or by a sludge removal pump.
