The Park Process OilDawg™ is an above ground steel tank coalescing type separator that utilizes polypropylene or PVC coalescing materials to capture and remove oil droplets from the outgoing water flow. Oil/water separators are commonly used to separate oils from a variety of wastewater and stormwater discharges and industrial waste streams. A properly designed, installed, and operated oil/water separator prevents the entry of unacceptable levels of oil contamination into a storm or sanitary sewer system.
The OilDawg™ Oil/Water Separator (OWS) is a coalescing type oil/water separator that uses a containerized tubular polypropylene media (SepPaks) to accomplish the coalescing function. The coalescing tubes attract oil droplets, binding them together on the surface of the media and forming larger droplets that are more buoyant, causing them to rise faster. The orientation of the OilDawg’s SepPak tubes allows the oil droplets to rise unimpeded to the surface of the vessel. Solids in the flow settle to the bottom of the vessel using the same channels. The OilDawg™ utilizes an inlet distribution manifold that evenly distributes the incoming flow across the width of the vessel. The inlet chamber’s down baffle enhances the settling effect and induces laminar flow to the incoming stream. The inlet chamber and media sumps are equipped with clean-out ports for easy removal of built-up sludge.
The SepPaks are contained in removable baskets that can be easily lifted out of the unit for cleaning and/or replacement. The SepPak coalescing tubes are made in two diameters with the larger diameter tube baskets installed in front of the smaller diameter tube baskets. This design discourages fouling from the incoming flow and enhances the separation process. The larger diameter tubes have less square footage of surface area per unit volume and offer the initial coalescing surface for oil droplets to collect and solids to settle. The smaller diameter tubes with more surface area per unit volume are more effective in dealing with the smaller diameter oil droplets.
An adjustable rotating pipe skimmer is installed downstream of the SepPaks to remove the coalesced floating oil. Water passes under a down baffle and over the water weir before exiting the vessel.
The Park Process OilDawg™ Oil/Water Separator is designed to capture and remove oils from wastewater and stormwater discharges, effectively ensuring environmental compliance in a wide range of above-ground applications.
