US Patent:

57025932, Dec 30, 1997

Filed:

May 14, 1996

Appl. No.:

8/645515

Inventors:

Scott W. Horsley - Boston MA
Winfried Platz - Barnstable MA

Assignee:

Stormtreat Systems, Inc. - Barnstable MA

International Classification:

C02F 332

US Classification:

210122

Abstract:

A method and apparatus for treating contaminated stormwater runoff from roads and adjacent lands. A multi-stage and self-contained integrated module is designed to collect the first flush of stormwater runoff (which contains the majority of pollutants) and to treat the pollutants using sedimentation, filtration and constructed wetlands. The apparatus is mass-produced to provide standardized hydrologic controls, important to the reliability of the constructed wetland component of the apparatus. Raw stormwater enters the central sedimentation chamber of the apparatus which is divided into multiple segments designed to provide a series of sedimentation/filtration chambers. At least one chamber is provided with a removable filter bulkhead. Effluent from the final sedimentation chamber is discharged to the constructed wetland system which surrounds the central sedimentation tank. Water flows through the perimeter wetland system in subsurface/saturated conditions and contacts the root zone of the constructed wetland where biochemical interactions attenuate pollutants.

Abstract:

A method and apparatus for treating contaminated stormwater runoff from roads and adjacent lands. A multi-stage and self-contained system designed to collect the "first flush" of stormwater runoff (which contains the majority of pollutants) and to treat the pollutants using sedimentation, filtration and constructed wetlands. The apparatus is mass-produced to provide standardized hydrologic controls, important to the reliability of the constructed wetland component of the apparatus. Raw stormwater enters the central sedimentation chamber of the apparatus which is divided into multiple segments designed to provide a series of sedimentation/filtration chambers. Each chamber is divided by a removable filter bulkhead sequenced from coarse to fine sediment sizes. Effluent from the final sedimentation chamber is discharged to the constructed wetland system which surrounds the central sedimentation basin. Water flows through the perimeter wetland system in subsurface/saturated conditions and contacts the root zone of the constructed wetland where biochemical interactions attenuate pollutants.
