Filed:

Sep 6, 2012

Appl. No.:

13/605824

Inventors:

William Robert Hannemann - Ocean Gate NJ, US
Albert Mayer Cohen - West Long Branch NJ, US

Michael Hannemann - Toms River NJ, US

Assignee:

Storm Drain Technologies, LLC - Ocean NJ

International Classification:

E03F 5/14
C02F 1/00

US Classification:

2107472, 210513, 210241, 210322, 210767

Abstract:

A portable fluid treatment apparatus includes a container with an interior wall between the inlet pipe and the outlet pipe which defines a bottom space between the bottom of the wall and the bottom interior surface of the container. A series of collectors in the container direct the flow of the inlet fluid and promote sedimentation from the fluid. The inlet fluid flows under the wall and up to a discharge pipe equipped with a vent. Multiple sedimentation units are connected together in series and mounted on a trailer for transport to a construction site.

Abstract:

A stormwater treatment unit comprising a containment vault having an inlet and an outlet separates debris from a flow of stormwater through the unit. The water flow is controlled by a wall which directs flow from the inlet to the outlet through a reservoir of fluid in the unit. Debris separation by density occurs whereby lighter elements such as oil float on top of the fluid and heavier elements such as sediment collect at the bottom of the unit or in collectors in the reservoir. A wire mesh, deflector, and/or ripple boards placed beneath the inlet further increase efficiency of the separation, and a vent pipe is placed above the outlet to release pressure built up in the outlet during operation. A stormwater treatment system and method of retrofitting an existing stormwater trunk line locates the stormwater treatment unit in an off-line position from an existing drainage trunk line.
