In another embodiment, the vessel includes a bed of compost and at least one other natural media filtration agent. The vessel includes a wastewater inlet that is in fluid communication with one or more of the natural media filtration agents. The vessel includes a wastewater outlet that is in fluid communication with one or more of the natural media filtration agents.Type: ApplicationFiled: July 16, 2010Publication date: November 4, 2010Applicants: ALCOA INC., CORPORATE ENVIRONMENTAL SOLUTIONS LLCInventors: John R.

Publication number: 20100270220Abstract: The present invention relates to a filtration tank intended to be buried and for containing wastewater in particular, the tank (100) comprising a casing (110) having an upper part (200) and a lower part (300), the tank being provided internally with a means for reinforcing the structure of the casing (110) so that it can withstand the pressure exerted by the surrounding material when the tank (100) is buried and is not completely filled. According to the invention, the reinforcing means (600, 600?) comprises voussoirs (610, 610?) bearing against the upper part (200) and in that the tank (100) incorporates means (650d, 670) for absorbing the supporting forces of the voussoirs (610, 610?) so as to transfer said forces onto the bottom (310) of said tank. A tank is thus obtained which withstands being buried without deforming even though it may be only partially filled.Type: ApplicationFiled: December 5, 2008Publication date: October 28, 2010Inventor: Yannick Juhere

Patent number: 7790035Abstract: Described are a tertiary disinfection system and process for treating a liquid effluent from a domestic secondary treatment unit. The liquid effluent has pathogenic micro-organisms, remaining suspended solids and dissolved organic pollutants. The system has an inlet, a subterranean initial treatment zone filled with a filtering material for removing some suspended solids, dissolved organic pollutants and pathogenic micro-organisms. The initial treatment zone allows the liquid effluent to percolate downward. The system also has a subterranean polishing zone extending horizontally outward from the initial treatment zone, and filled with a filtering material having pore sizes allowing upward capillary dispersion of the liquid effluent. The system also has a subterranean aeration zone having an interface with the initial treatment zone and the polishing zone, to provide aeration enabling aerobic accommodation of microflora for disinfection of the effluent.Type: GrantFiled: March 13, 2008Date of Patent: September 7, 2010Assignee: Premier Tech Technologies LTEEInventors: Jean-Pierre Dautais, Roger Lacasse, Denis Pettigrew, Pierre Talbot

Patent number: 7776211Abstract: A wastewater treatment system and process includes a treatment system for biologically treating wastewater to produce substantially clean water effluent and byproducts. The treatment system includes an array of rotating media wheels for sustained algae growth. The media wheels are supported so that the algae rotates into and out of the wastewater for exposure to sunlight. One byproduct is algae removed from the rotating media wheels, which may be provided to other processing facilities to produce, for instance, bio-diesel fuel. Waste CO2 may also be provided to the facility for enhanced algae growth. Bacteria is provided to form a symbiotic relationship with the algae, fueled by sunlight to effectively remove toxic materials from the wastewater. Rotation of the media wheels can be accomplished by air jets that also operate to dislodge excess algae as a byproduct of the system and process.Type: GrantFiled: September 17, 2007Date of Patent: August 17, 2010Assignee: Algaewheel, Inc.Inventor: Christopher A.

Patent number: 7762740Abstract: By providing an easily transported, filler component system, leaching field forming elements for establishing a series of flexible design passageways into which the desired fill material is placed, a highly effective, easily installed, competitively priced with enhanced biological habitat underground fluid distribution system is achieved. In accordance with the present invention, the desired passageways are quickly and efficiently created by employing pre-folded cardboard panels, or other pervious materials, placing the materials in an excavated location or site in cooperating relationship with each other for creating the desired leaching fields. In the preferred embodiment, two, substantially identical, pre-folded cardboard panels are employed and are positioned in juxtaposed, cooperating, spaced, facing relationship with each other, establishing a central passageway therebetween.Type: GrantFiled: June 30, 2008Date of Patent: July 27, 2010Inventors: Wayne Burritt, Robert Butler, Frank A. Schaub

Patent number: 7749384Abstract: An apparatus is provided that includes: a containment system 208 having at least one sidewall and bottom that are substantially impermeable to a passage of water; a distribution system 124 to introduce an aqueous stream comprising nitrates into the containment system; a de-nitrification system 128 comprising a de-nitrification media, the media being contained within the containment system; a pump to pressurize the stream and cause the stream to pass through the de-nitrification media, thereby converting at least most of the nitrates into nitrogen gas and forming a treated stream; and a collection system 132 to remove the treated stream from the containment system.Type: GrantFiled: May 22, 2008Date of Patent: July 6, 2010Inventors: David W. Patton, Gerald Lee Lamb, Jamie Lee Miller

Patent number: 7744756Abstract: An apparatus for diverting wastewater in septic system comprises a top, a side adjoining and extending downwardly from the top, the top and the side form an inner volume and a partially open bottom. The bottom can be fully open. A first opening extends upwardly from the partially open bottom. A second opening, having a perimeter, is also on the side. The apparatus can be placed at outlet end of a trench to receive the trench pipe. The first opening, the open bottom and the inner volume permit the apparatus to be placed over a pipe without adjustments or modifications.Type: GrantFiled: July 8, 2008Date of Patent: June 29, 2010Assignee: Soil Horizons, Inc.Inventor: John R. Davis, Jr.
