OilDawg™ Oil-Water Separator

OilDawg™ Oil-Water Separator

Details

A Cost-Effective Way to Separate Oils from Wastewater and Stormwater

Pollution Reduction

Effectively captures and removes oil contamination from entering storm and sanitary sewer systems.

Easy Maintenance

Removable filter baskets, access hatchways, and drain ports allow for easy inspection and maintenance.

Flexible Design

Rotating pipe skimmer allows skimming level to be adjusted.

Efficient Performance

Designed for linear flow rate of approximately 1 ft./minute and ½ cubic foot of coalescing media per gpm of incoming flow.

Details

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.

How It Works

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.

About the OilDawg™

The OilDawg™ Oil/Water Separator consists of a tank constructed of steel and coalescing media made of polypropylene or PVC. Bolted down gasketed hatches on the lid allow inspection of critical parts and adjustment of oil weir without removing the entire lid.

Applications

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.

Stormwater Run-Off

Oil/Water Separators filter oil from stormwater discharges in roadways, parking lots, and airport tarmacs, ensuring environmental compliance.

Equipment Washpads

Equipment washing operations can produce oily wastewater that requires pre-treatment before discharge into the municipal sewer system.

Manufacturing Plants

Our Oil/Water Separator can be installed at manufacturing facilities to separate oils from wastewater produced in various plant processes.

Fueling and Vehicle Maintenance Facilities

Run-off from truck fueling facilities, gas stations, and maintenance shops requires pre-treatment with an Oil/Water Separator before discharging into the sanitary or stormwater sewer.

Refinery Wastewater

Our Oil/Water Separator can be used at oil refineries, petrochemical plants, chemical plants, and natural gas processing plants to separate oils and suspended solids from wastewater.

Power Generation Effluent

Hydroelectric, natural gas, and coal-fired power stations utilize Oil/Water Separators to ensure compliance with environmental regulations for effluent discharge.

Hydrocarbon Storage Facilities

The OilDawg™ can be installed at hydrocarbon storage facilities to effectively treat wastestreams that may be contaminated with crude oil.

Elevator Sump Water

Our Oil/Water Separator effectively removes and stores oils from elevator sump water wastestreams, allowing filtered water to drain into the sanitary sewer.

Steel Mills

Various processes employed at steel mills produce industrial wastestreams that require the use of an Oil/Water Separator for compliant effluent discharge.
