  • Stormwater treatment apparatus
    Patent number: 6350374
    Abstract: A liquid purification and separation apparatus for separation of pollutants in stormwater runoff is disclosed. This apparatus utilizes gravitational separation and tortuosity, resulting from a plurality of baffles both perpendicular to and oblique to the primary water flow direction, to trap substances less-dense and more-dense than water. The apparatus features improved resistance to pollutant remobilization through an interactive hydraulic design process resulting in greater pollutant retention.
