Coalescing Plate Interceptor Separator

Waste water enters the inlet nozzle into an enlarged coalescing section. This coalescing section is where heavier solids and sludge settle out of the waste water to the bottom of the vessel where it is discharged through the clean out nozzle. Waste water then flows through the perforated distribution baffle plate. After it is evenly dispersed, it flows down through the plate pack where oil rises to the top of the corrugations and coalesces with other oil droplets. The large oil droplets rise up through the plate pack to the oil/water interface. Coalesced oil will flow over an internally adjustable oil weir and is removed through the oil outlet nozzle. Light solids and sludge separation is simultaneously accomplished within the pack by settling to the bottom of the corrugations where solids are directed to the sludge drain. The flow out of the plate pack travels upward and spills over a fixed water weir, then exits the vessel through the water outlet nozzle for further downstream treatment or disposal. Our CPI Separators effectively remove oil droplets of 50 microns or larger, depending on fluid properties.
