Remove both oil and solids from wastewater! Discharge to the sewer!

Developed for treating wash water from heavy commercial and industrial washing operations, the SPT Series Integrated Pretreatment Systems integrate an inclined plate clarifier with an oil water separator to treat wash water for acceptable discharge to the sewer or surroundings.


The system flow is very efficient. After entering the inlet compartment, the oily wastewater then travels up the angled clarifier plates. These plates remove all suspended and settable solids which drop into a hopper below. After passing over a weir, the water flows through the separator coalescing media which removes all non-emulsified oil from the waste stream.
