Patent number: 8512555Abstract: A stormwater filter assembly includes a hood and an outlet tube within the hood for draining filtered stormwater. The outlet tube has a solid wall along at least a portion of its height, and an inlet above the solid wall. A second tube is disposed about the outlet tube defining a flow space therebetween for receiving filtered stormwater. The second tube includes a wall that is perforated along at least a portion of its height that overlaps with the solid wall of the outlet tube such that filtered stormwater that enters the flow space must move upward to enter the outlet tube. A filter media is disposed between the hood and the second tube through which stormwater travels during a filtering operation.Type: GrantFiled: February 4, 2010Date of Patent: August 20, 2013Assignee: Contech Engineered Solutions LLCInventors: Vaikko P. Allen, II, Scott A. de Ridder, Christopher S. Hersey, Daniel P. Cobb, Greg Kowalsky, Alan K. Stratton

Publication number: 20120298590Abstract: A system includes a tank with a lower chamber spaced from an outlet or upper chamber by a confinement deck. The deck includes one or more sockets for receiving one or more filter units. The lower chamber of the tank acts as a pretreatment sump to remove floating and nonfloating particulates, reducing the load on the filter units. The filter units are configured for radial and/or upward flow of the fluid from the lower chamber. The filter units may be removed for ease of tank maintenance and replacement of filters.Type: ApplicationFiled: June 5, 2012Publication date: November 29, 2012Inventors: Norman L. Olson, Brian R. McLaughlin, Daniel P. Cobb, Vaikko P. Allen, II, Derek M. Berg

Patent number: 8318015Abstract: A stormwater filtration system suitable for treatment of stormwater runoff in a developed environment uses a primary treatment bay that includes a filtration bed with live plant matter. A second treatment bay treats water that exceeds the maximum throughput of the primary bay. A reservoir stores treated runoff to water the plants during dry weather. Removable trays on the surface of the primary filtration bed provide plants suitable for ground cover. Additional bays expand the filtration bed throughput and accommodate extended root systems. A flow control may be provided for the primary treatment bay.Type: GrantFiled: January 18, 2012Date of Patent: November 27, 2012Assignee: Contech Engineered Solutions LLCInventors: Vaikko P. Allen, II, Jeremiah M. Lehman, James H. Lenhart, Jr., Hong Lin, Daniel P. Cobb, Gregory W Byrne

Publication number: 20110062088Abstract: A system and related method for separating floating and nonfloating particulate and entrained, suspended, and/or dissolved contaminants from a fluid. The system includes a tank with a lower chamber spaced from an outlet or upper chamber by a confinement deck. The deck includes one or more sockets for receiving one or more filter units for fluid treatment. In addition, the lower chamber of the tank acts as a pretreatment sump to remove floating and nonfloating particulates, thereby reducing the load on the filter units. The filter units are configured for radial and/or upward flow of the fluid from the lower chamber. The filter units may include one or more filter media through which the fluid pass prior to exiting the tank. The filter units include a removable screening retainer for retaining the filter media and/or to screen relatively large contaminants. The filter unit may be removed for ease of tank maintenance and replacement of filter media.Type: ApplicationFiled: August 11, 2010Publication date: March 17, 2011Inventors: Norman L. Olson, Brian R. McLaughlin, Daniel P. Cobb, Vaikko P. Allen, II, Derek M. Berg

Patent number: 7297266Abstract: A screen apparatus for improved separation of particulates from a fluid stream. The screen is configured and arranged to filter relatively large particulates from the fluid stream as the fluid stream passes from a storage chamber of the tank to a tank outlet. The screen is removably affixed to a diverter, such as a baffle, used to divert a portion or all of the fluid into the storage chamber. The screen is preferably shaped to substantially conform to the shape of the diverter to aid in the smoothing of the fluid flow within the retention section of the tank. The screen may be entirely porous, or it may be non-porous at its leading edge to minimize particulate build-up at the transition from the tank interior wall to the screen. The apparatus may optionally include a second screen to provide additional filtering of floating particulates as the fluid level in the tank exceeds the crown elevation of the inlet.Type: GrantFiled: December 20, 2004Date of Patent: November 20, 2007Assignee: Contech Stormwater Solutions Inc.Inventors: Daniel P.

Patent number: 7296692Abstract: A fluid separation system includes a tank with a storage chamber for retaining floating and non-floating particulates. The tank includes a baffle for retaining floating particulates within the storage chamber and for directing flow out of the storage chamber. The tank also includes a bypass with an inlet flow control zone and an outlet flow control zone. The flow control zones are separated by a weir sized and positioned to regulate the fluid flow through a baffle port into the storage chamber. The weir also provides control of the flow rate at which incoming fluid is diverted directly through the bypass to the tank outlet rather than into the storage chamber. The baffle and/or the weir may be curved, and the baffle may include a complex curve, to aid in the smoothing of the fluid flow within the storage chamber to improve particulate separation.Type: GrantFiled: December 17, 2004Date of Patent: November 20, 2007Assignee: Contech Stormwater Solutions Inc.Inventors: Vaikko P. Allen, II, Daniel P. Cobb

Patent number: 7186058Abstract: A stormwater runoff detention system includes a system including an inlet, a first surge chamber, a second surge chamber and one or more storage chambers. The first surge chamber is connected to receive stormwater from the inlet prior to the second surge chamber or the storage chamber. The first surge chamber includes a discharge outlet and an overflow outlet to the storage chamber. The second surge chamber is connected to receive stormwater from the inlet primarily after the first surge chamber has begun overflowing to the storage chamber. The second surge chamber includes a discharge outlet and an overflow outlet to the storage chamber or to a second storage chamber.Type: GrantFiled: January 14, 2005Date of Patent: March 6, 2007Assignee: Contech Stormwater Solutions Inc.Inventors: James C.
