Virtually any industrial user who controls or collects storm water and discharges it through a pipe, drain or other outlet, into a storm sewer system or navigable waterway must comply with the National Pollutant Discharge Elimination System (NPDES). A working oil water separator is an important part of a storm water drainage system designed for facility compliance with the NPDES storm water program.

AquaSweep™ Gravity Oil Water Separators are designed for gravity-induced separation of oil from water. This system is passive, meaning that the attributes of the incoming oily water will directly determine the characteristics of treated outgoing water. The separators are 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.
