Patent number: 10570578Abstract: Novel streamwater remediation systems and processes are presented. The disclosed systems involve design and placement of geometric volumes of porous media of variable hydraulic conductivity within the streambed to enhance hyporheic exchange (exchange of water from the stream or constructed urban waterway compartment to the porous media, or streambed, compartment). The disclosed systems may help improve water quality in various ways, for example through the removal of contaminants from water as it passes through the streambed. In some embodiments, contaminant removal is achieved by microbes and/or reactive geomedia incorporated into the streambed structures. By pairing hydrologic/flow structures with bacteria or reactive geomedia, diverse contaminants such as metals, nutrients, organics, pathogens, and more can be sorbed, deactivated, assimilated, transformed to harmless chemicals, and otherwise removed from the water.Type: GrantFiled: May 18, 2015Date of Patent: February 25, 2020Inventors: John McCray, Skuyler Herzog, Chris Higgins

Publication number: 20090026135Abstract: The present invention provides a mixed bacterial culture, designated as the culture Atz Mix 1, which degrades atrazine at various temperatures (10° C. to 30° C.) in a wide range of atrazine concentrations (several ppb to ten thousand ppm), without formation of toxic metabolites. Atz Mix 1 is a stable mixed culture and includes catabolic genes trzN, atzB, atzC coding the enzymes for the degradation of atrazine to cyanuric acid, and the gene trzD coding the enzymes for subsequent opening of s-triazine ring. The invention further includes a microbiological method of degrading atrazine and other s-triazine compounds for remediation of atrazine-contaminated soils, even those rich in nitrogen, as well as for accelerating the process of atrazine mineralization in waste waters containing high concentrations of s-triazine compounds.Type: ApplicationFiled: August 20, 2008Publication date: January 29, 2009Inventors: Dubravka Hrsak, Maja Havriluk

Patent number: 7481925Abstract: A water filtration panel and a system containing the same are disclosed. The water filtration panel include a substantially rigid frame having a first face, a second face, and an inner dimension; a sheet of fabric material that permits water to flow therethrough, the fabric material being secured to the substantially rigid frame in a manner whereby substantially all water passing through the inner dimension of the frame passes through the fabric material; a sealing member connected to the first face of the substantially rigid frame; and an adjustable expansion member contacting the second face of the substantially rigid frame. Also disclosed is a retainer that is used to couple the fabric material to the substantially rigid frame.Type: GrantFiled: October 25, 2004Date of Patent: January 27, 2009Assignee: Gunderboom, Inc.Inventor: Harold B. Dreyer

Patent number: 7459075Abstract: The present disclosure provides for a system and method that intensely oxidizes water as it navigates through a system and accurately, controllably neutralizes the oxidation by-products before the water exits the system.Type: GrantFiled: June 30, 2005Date of Patent: December 2, 2008Assignee: Disney Enterprises, Inc.Inventors: Ivey Burns, Thoram Charanda, Thomas J. Nicodemo, Richard Davis, Janell Crowder

Patent number: 7378021Abstract: A wastewater treatment system includes a tidal, sequential vertical flow marsh cell system having at least three marsh cells in serial forward fluid communication. Incoming wastewater to be treated is channeled to at least the first and a second marsh cell, and a portion of water exiting a final marsh cell, to the first marsh cell surface. Each marsh cell is alternately flooded and drained for enhancing aeration of incoming water and marsh cell contents, which include media and plant roots having biofilms growing thereon, the biofilms including a population of nitrifying and denitrifying bacteria, for achieving substantially simultaneous nitrification and denitrification of the wastewater.Type: GrantFiled: April 27, 2007Date of Patent: May 27, 2008Assignee: Worrell Water Technologies, LLCInventors: David C. Austin, Eric Lohan

Patent number: 7326335Abstract: There is disclosed an apparatus for removing solids from water in a canal during or immediately after a rainstorm. The apparatus includes a plurality of filters and a carrier. The filters filter the solids from the water while moving in and taking impact from the water. The carrier carries the filters in a cycle.Type: GrantFiled: November 2, 2005Date of Patent: February 5, 2008Assignee: Taiwan Water & Soil Instrumentation, Inc.Inventor: Hsu-Chen Chuang

Patent number: 7297258Abstract: The coupling of a sewer treatment station to a treatment plant for the flocculation and flotation of water streams and the insertion of said treatment plant for the flocculation and flotation of water streams into a water treatment station. The sewer treatment station is installed upstream from the flocculation and flotation treatment station, in such a way that the outlet of said station is directly connected to the inlet of the flocculation and flotation treatment plant disposed next to the stream bed or next to and interconnected thereto by means of a varying flow canal. The insertion has dynamic introduction of the process of treatment for the flocculation and flotation of fluid beds, all in a closed canal, wherein the flow of secondary streams (E) is dynamically and continuously submitted to flocculation and flotation techniques in an induced flow canal (FE) in the water treatment station.Type: GrantFiled: May 25, 2004Date of Patent: November 20, 2007Inventor: João Carlos Gomes De Oliveira
