US Patent:

7001527, Feb 21, 2006

Filed:

Oct 8, 2003

Appl. No.:

10/681766

Inventors:

R. Russell Stever - Sparks NV, US
Ben R. Urbonas - Dencer CO, US
Jonathan E. Jones - Boulder CO, US
Andrew Earles - Boulder CO, US
Edward Scott Sarratt - Reno NV, US
Eric Richard Schneider - Reno NV, US
Steven C. Phelps - Reno NV, US

Assignee:

Jensen Enterprises - Sparks NV

International Classification:

B01D 21/02

US Classification:

210747, 210801

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 treatment of water volume rather than flow rates, using vertically stacked water columns of varying depths to settle small particles. An overflow structure diverts excessive liquid without interfering with purification and separation, and can be placed integrally within or external to the apparatus receptacle.
