The SPT Series Integrated Pretreatment Systems, which integrate an oil water separator with an inclined plate clarifier, have been specially developed for treating wash water from heavy commercial and industrial washing operations with discharge to the sewer. The clarifier section removes all settable solids while the oil/water separator section will remove all non-emulsified oil and odors from the waste stream.
These heavy-duty stainless steel systems, are considered to be the “Best Design in the Industry” and the “Best Value on the Market”!
