Publication number: 20120181235Abstract: The present invention is directed to an assembly and a method of treating rainwater to produce potable water. A compact and easy-to-install apparatus is achievable as a result of a simple, yet highly effective sanitisation method.

Patent number: 8142666Abstract: Devices, apparatus, systems and methods of using baffle boxes with turbulence deflectors and flow spreaders. Turbulence deflectors are added about the inlet port of a baffle box, and a flow spreader is added centrally beneath an outlet port to increase removal efficiency of pollutants and prevent the conveyance of pollutants down stream.

The water harvesting device comprises a tank portion for containment of water and a water entry portion for receiving water, particularly rainwater from a building water collection system such as an eaves and downspout configuration. Debris typically accompanying rainwater as it exits from the downspout of the building collection system is diverted away from the water entry area allowing for better water collection efficiency, preventing backing of water and reducing operator maintenance of the device.Type: GrantFiled: August 12, 2009Date of Patent: January 17, 2012Assignee: Green Ripple Innovations Inc.Inventor: Scott William Allan

Patent number: 8088279Abstract: A runoff water filter is defined by an elongate, tubular mesh container filled with a filter medium that is selected for the ability of the filter medium to remove target pollutants from the runoff water. In a first disclosed embodiment, vermiculite is used as the primary filter medium for its ability to bind cationic compounds, principally zinc, from water running off metal buildings. Other filter media may also be employed to remove other target pollutants.Type: GrantFiled: April 23, 2008Date of Patent: January 3, 2012Assignee: Cleanway Environmental Partners, Inc.Inventors: Stephen McInnis, Matthew Moulton

Publication number: 20110315617Abstract: A hood that mounts around an outlet of a catch basin with a cover having a proximal end and distal end; the proximal end being pivotally attached to the hood. The cover pivots between a closed sealed position that substantially prevents water born contaminants from passing through the access opening and an open position that allows access to the access opening. The cover is made from a flexible material to allow the cover to be lifted from the closed sealed position in a substantially vertical path that allows access to the outlet of a catch basin.Type: ApplicationFiled: May 20, 2011Publication date: December 29, 2011Inventors: Lee A. Duran, Thomas J. Mullen, III

Patent number: 8083937Abstract: The present invention is a storm water filter system for filtering floatable debris and non-floating pollutants from storm water passing through a storm water drain system vault. The storm water filtering system has a vault having chamber having a wall between the inlet thereto and the outlet therefrom. The wall has a filter passageway therethrough for filtering the storm water and a floatable baffle panel covering a second passageway therethrough for capturing floatable debris and trash from the storm water. Storm water entering the vault inlet passes through a filter element and out the outlet and also can pass under the floating baffle panel when the floatable baffle panel is floated to a raised position to thereby prevent storm water from accumulating on the inlet side of the wall.Type: GrantFiled: December 4, 2009Date of Patent: December 27, 2011Inventor: Thomas H. Happel

Publication number: 20110284441Abstract: A vortex flow type water surface control device for a draining device is provided. The vortex flow type water surface control device may include an inflow pipe, an outflow pipe, an intercepting pipe, and a separating weir that is disposed to block the intercepting pipe and the inflow pipe from the outflow pipe. The vortex flow type water surface control device may also include a control plate that is disposed between an opening of the inflow pipe and an opening of the intercepting pipe. A height of the control plate may be higher than at least a height of the separating weir. The control plate may be apart from the separating weir, and may approximately extend to a center axis of the intercepting pipe.Type: ApplicationFiled: August 4, 2011Publication date: November 24, 2011Applicants: TOKYO METROPOLITAN GOVERNMENT, NIPPON KOEI CO. LTD., TOKYO METROPOLITAN SEWERAGE SERVICE CORPORATIONInventors: Ikuo UEMURA, Hirofumi ISHIWADA, Shouichi BANBA, Aya UCHINO, Tsuneo OCHIAI, Hiroshi KOMATSU, Shigeki NISHIMURA, Shigeru TUKADA

Patent number: 8062522Abstract: Disclosed is a system for reducing the demand of wastewater volume flowing through a wastewater collection piping system and thereby increasing the effective capacity of the system. A portion of the wastewater is diverted from a sewer main. The solids are separated from the liquid, for example, by a vortex separator. The recovered liquid can be treated and made available for local reuse. The concentrated solids are reintroduced into the main sewage line in a portion that adjusts the wastewater loading in the sewer main to a predetermined amount or predetermined range. Also disclosed is a system capable of reintroducing the concentrated solids into the sewer main in a portion that adjusts the solids loading in the sewer main to a predetermined amount or predetermined range.Type: GrantFiled: March 17, 2011Date of Patent: November 22, 2011Assignee: Ecolivegreen Corp.Inventor: Paul L. Culler

Patent number: 8062531Abstract: An underground stormwater management system includes a receiving tank connected to a source of non-first flush runoff and a storage chamber that accumulates stormwater runoff for discharge to a storm drain. The storage chamber includes a first inlet connected to a source of first flush runoff, a second inlet connected to receive overflow from the receiving tank, a first discharge and a second discharge above the first discharge. First flush is discharged from the first discharge and is filtered before reaching the storm drain. The receiving tank assists in delaying the receipt of non-first flush runoff into the storage chamber during a major rain event. During major rain events runoff is also discharged from the storage chamber directly to the surrounding media.Type: GrantFiled: July 30, 2009Date of Patent: November 22, 2011Assignee: Lane Enterprises, Inc.Inventor: Edward H. LoBello
