An incubator comprising a set of sub-portions associated with said set of concentrations of dissolved oxygen is established, each sub-portion of the incubator having a different concentration of dissolved oxygen. A volume of effluent from each sub-portion of the lagoon is transmitted to a corresponding sub-portion of an incubator having a substantially similar concentration of dissolved oxygen as said sub-portion of the lagoon. A first remediated volume of effluent is generated in said corresponding sub-portion of the incubator responsive to proliferating a first microorganism which uses a first compound in said volume of effluent as substrate for growth, the first microorganism enabling a first chemical reaction which alters the first compound.Type: ApplicationFiled: October 9, 2008Publication date: April 15, 2010Applicant: VERDURE TECHNOLOGIES, INC.Inventor: Mark Terry

Patent number: 7695620Abstract: This application relates to an apparatus and method for treating effluent. The effluent may be derived, for example, from an upstream secondary treatment plant. The apparatus employs a plenum positionable within a fluid-impervious container. The plenum includes a fluid filter portion containing a hydrophilic material, such as peat, capable of transporting effluent by capillary action and a fluid collection portion for receiving effluent from the upstream effluent source. The apparatus also includes a fluid wicking conduit containing hydrophilic material for wicking effluent from the fluid collection portion. The fluid wicking conduit may be configured so that any appreciable amount of effluent introduced into the apparatus will be wicked even if the amount is substantially less than the fluid holding capacity of the fluid collection portion of the plenum. This enables the apparatus to operate substantially continuously and passively so long as some effluent is resident in the plenum.Type: GrantFiled: July 17, 2008Date of Patent: April 13, 2010Inventor: Curt Kerns

Patent number: 7686956Abstract: The invention is directed to a water purification system to remove pollutants from surface run-off water that has flowed into storm water drainage channels. A tank having an open reservoir region is positioned in the drainage channel or adjacent to the channel so as to permit water to flow through an upstream port of the tank and pool within the open reservoir region. The tank has a downstream port through which water pooled within the reservoir region may flow if the level of the pooled water sufficiently increases as a result of a rise in the flow level of the water in the drainage channel. The open reservoir region contains bioremediation plants having the physical property of removing pollutants from the pooled run-off water contained in the reservoir region.Type: GrantFiled: May 22, 2006Date of Patent: March 30, 2010Inventor: Kenneth Casebier

Patent number: 7682503Abstract: An improved and more efficient design for an air driven algae filtration system is achieved because there are no moving parts other than an air pump, and the air is used twice. After using air to circulate water through a filtration unit, the air, still under pressure, is separated from the water. The air is then plumbed to other apparatuses or used for cooling. This allows the filter to be utilized using less electricity. The water is de-gassed before reaching the algae filter. Therefore, no splash guard is necessary to prevent water from splashing the lights. With no splash guard, lower wattage lights can be used to illuminate the algae. This also increases the efficiency of this system. This filter also lends itself to maintaining a reef aquarium.Type: GrantFiled: September 10, 2008Date of Patent: March 23, 2010Inventor: Joe Norris

Patent number: 7674378Abstract: A self-contained wetlands treatment system to remove pollutants from water and treat stormwater runoff or other grey water. This is system and method wherein the water is passed through a wetland filtering and treatment system. This invention removes solids, metals (dissolved/particulate), nutrients (dissolved/particulate), oils, and bacterial contaminants from the water. The system and system housing can be fabricated, built, and assembled in a broad range of sizes and materials to accommodate and treat a broad range of influent flow rates.Type: GrantFiled: October 31, 2007Date of Patent: March 9, 2010Assignee: Modular Wetland Systems, Inc.Inventor: Greg B.

Publication number: 20100051540Abstract: Materials, compositions, substances and methods and systems for stormwater treatment in wet ponds, dry ponds and a green roof system. A first embodiment provides in-situ treatment unit within the retention pond by withdrawing the stored stormwater to circulate the stored stormwater into the in-situ treatment unit to sorb nitrogen from the stored stormwater. A second embodiment provides uses a riprap apron, a perforated riser located at the bottom of the riprap apron and a goetextile media encased in a sorption media jacket around the perforated riser. A third embodiment provides a green roof stormwater treatment system that includes protection for waterproofing and insulating the roof, a pollution control media layer for filtration and sorption of solids and dissolved materials found in stormwater, a growing media for growing vegetation, and a cistern to store the runoff stormwater between irrigation events.Type: ApplicationFiled: August 28, 2008Publication date: March 4, 2010Applicant: University of Central Florida Research Foundation, Inc.Inventors: Martin P.
