AquaSweep Model


Wastewater that contains significant amounts of oils or solids interfere with the proper drainage and treatment of effluent water and must be treated before being discharged into the sanitary sewer system. To comply with Pretreatment water quality standards of the EPA Clean Water Act and local plumbing codes, using an sand-oil interceptor for waste-water pretreatment is recommended. The ParkUSA® AquaSweep™ AQ Series is an oil-water separator that utilizes an enhanced gravity separation method of oil from oil-water mixtures. The Model AQU is designed for underground (direct-bury) application, whereas the Model AQA is design for aboveground (freestanding) applications. Engineers specify the AquaSweep™ oil water separator to ensure wastewater pretreatment meets project and code requirements.​

AquaSweep™ gravity oil water separators are designed for gravity-induced separation of oil from water. This system is passive and the oil/solid concentrations in the influent oily water can directly determine the characteristics of treated effluent wastewater. The separator is designed for gravity removal of non-emulsified hydrocarbons, i.e. motor oils, lightweight oils, and related petroleum products with a specific gravity of less than 1.0. Oily wastewater enters the AquaSweep™ separator, where the flow and turbulence of incoming water is reduced. Fluid then flows through various pre-selected coalescing materials to accelerate the separation process. The buoyant properties of the hydrocarbons cause oil droplets to rise and combine into larger oil globules while passing through the coalescing media. The globules rise to the surface and float on top of the water, while sludge and other matter settle and accumulate at the bottom of the tank compartment. The treated wastewater then exits the separator and enters the sanitary sewer system. Accumulation of oil and sludge within the separator is contained until it can be removed and disposed of properly. An optional oil-stop valve can be used to ensure that no oil leaves the separator if the AquaSweep™ separator oil storage capacity has been exceeded. ​
