Patent number: 7740752Abstract: A system for separating suspended and dissolved materials in a fluid having a pH offset from neutral is disclosed. It employs a plurality of stacked, generally flat treatment beds each having a surface angled downward for receiving the fluid. Since the fluid is spread over a large surface, its velocity slows causing suspended materials to drop out of the fluid as a sludge. A pH correction device may add an agent to the flowing fluid which will bring the pH closer to neutral thereby causing said dissolved materials to precipitate out and into the sludge. Atmospheric oxygen may also be used to effect the precipitation. Portions of the beds may be isolated and the sludge collected resulting in a fluid having substantially less suspended and dissolved materials at a pH and temperature closer to normal. Energy may be produced from the movement of liquid through the system or from the heat energy of the fluid. Magnetics may be utilized to improve the precipitation of solids.Type: GrantFiled: August 8, 2007Date of Patent: June 22, 2010Inventor: Christopher S. Gillis

The clarifier compartment has at least one vertical sidewall extending from a bottom of the clarifier compartment to a top of the clarifier compartment. The clarifier compartment has a cross-sectional area that varies over at least a portion of a height of the clarifier compartment such that the velocity of influent just prior to entry into the sludge blanket is less than the velocity of influent just after entering the clarifier compartment. The sludge blanket clarifier preferably has one or more flocculator modules disposed in the clarifier compartment to aid in flocculation and distribution of influent.Type: ApplicationFiled: June 2, 2008Publication date: December 3, 2009Inventors: R. Lee Roberts, Mark Kevin Addison, Karl Michael Kyriss

Patent number: 7617940Abstract: A device in connection with a separator for cleaning or reaming such a separator. The separator includes a tank or a body (2) with an inlet and at least one outlet (5, 6). A transport pipeline (3) is connected to the inlet for the supply of fluid that is to be separated in the separator. The transport pipeline (3) extends from the inlet through the separator body (2). Part (6) of the line that is located inside the separator body (2) is provided with perforations or slits (7) so that fluid that arrives in the transport pipeline (3) flows into the tank through the perforations/slits (7). Mechanical equipment for cleaning the transport pipeline (3) is designed to be sent from a magazine through the separator body (2) and on via a pipe loop back to the magazine.Type: GrantFiled: February 15, 2006Date of Patent: November 17, 2009Assignee: Norsk Hydro ASAInventors: Per Eivind Gramme, Gunnar Hannibal Lie

Patent number: 7582216Abstract: A water treatment system having a system inlet to receive a fluid flow, a treatment chamber, a first system outlet, and a second system outlet. The treatment chamber has an inlet in communication with the system inlet and an outlet in communication with the first system outlet, and is adapted to remove one or more contaminants from the fluid flow. The second system outlet is separated from the system inlet by a weir that prevents the fluid from passing into the second system outlet when the fluid is below a predetermined height, and allow at least a portion of the fluid to pass into the second system outlet without passing through the treatment chamber when the fluid is above a predetermined height. The second system outlet is isolated from the first system outlet such that fluid passing through the first system outlet can not impinge upon the treatment chamber outlet.Type: GrantFiled: August 22, 2007Date of Patent: September 1, 2009Assignee: Imbrium Systems Corp.Inventors: Justin Arnott, Brian Lee

Publication number: 20090211960Abstract: A fluid treatment tank for use in a well fluid processing system. The tank is divided into at least three compartments, including an oil treatment compartment for receiving oil from a separator vessel of the well fluid processing system so as to allow stabilization and/or final separation and treatment of the oil, a reject treatment compartment for receiving reject fluid from one or more water treatment units of the well fluid processing system so as to allow gravitational separation of heavier and lighter components of the reject fluid, and a water treatment compartment for receiving de-oiled water from one or more water treatment units of the well fluid processing system so as to allow degassing and/or final separation of the water. Also, a well fluid processing system including such a fluid treatment tank.Type: ApplicationFiled: March 14, 2007Publication date: August 27, 2009Applicant: Aibel ASInventors: Pal Jahre Nilsen, Matteo Chiesa, Peder Hansson, Helge L.

Publication number: 20090206027Abstract: An apparatus for use with settling tanks for recycling drilling fluids used in the drilling of wells is provided where the tank includes a plurality of compartments. Used drilling fluid containing well cuttings or “solids” is pumped into a receiving compartment of the tank and directed towards a flow-reversing barrier. Reversal of the flow causes heavier solids to settle to the bottom of the tank. As fluid fills the receiving compartment, it flows downstream into an adjacent compartment by passing through a flow-restricting baffle that causes more solids to settle to the bottom of the tank. As fluid overflows from compartment to compartment in the tank, it passes through successive flow-restricting baffles causing further solids to settle to the bottom of the tank. Fluid is removed from the collecting compartment of the tank to be used again in drilling operations.Type: ApplicationFiled: April 20, 2009Publication date: August 20, 2009Inventor: Darin Merle Harding

Publication number: 20090184049Abstract: A buoyant material trap having a treatment tank with a base wall and a vertically-extending sidewall, a feed pipe to introduce fluid at a first location in the tank, and an exit pipe to remove at least a portion of the fluid from a second location in the tank. One or more wall structures form a circuitous passage between the first location and the second location. The wall structures are open at the top and substantially prevent fluid from passing below the passage, but allow buoyant material to rise above the passage. The walls may extend to the bottom of the tank to prevent fluid from passing beneath them, and may be removably installed in the tank to facilitate cleaning. An overflow chamber may be provided to receive buoyant material. The sidewall may have a spout and be adapted to empty the tank by tilting.Type: ApplicationFiled: January 17, 2008Publication date: July 23, 2009Inventors: Christopher Adam Murray, Balreet Singh Dandiwal, Darren Francis Lawless, Gregory Richard Williams

Patent number: 7560035Abstract: Trough sides enclosing clarified liquid to be guided, and a trough septum, promote efficient clarifier operation. A first side has a liquid outlet, a second side is spaced from and opposite to the first side, and third and fourth sides extend spaced from each other between the first and second sides. The septum extends from the first side to a termination, and extends at an angle with respect to the third and fourth sides. Septum configuration divides the trough into a flow path from the first side to and around the termination back to the first side. The path extends sequentially over clarifier orifices in one row then over clarifier orifices in a next row along a path length. A path area is regulated along the length in direct proportion to length values so the trough flow velocity is constant all along the path.Type: GrantFiled: June 22, 2007Date of Patent: July 14, 2009Inventor: Charles Lonnie Meurer

Patent number: 7556157Abstract: A density current baffle for use in a clarifier tank has a first baffle portion having a lower end, an upper end and an intermediate central portion. The lower end of the baffle portion is coupled to a side wall of the clarifier tank. The upper end of the baffle portion being disposed away from the side wall of the clarifier tank. The intermediate central portion between the lower end and the upper end, the baffle portion is curved such that the upper end curves inward towards the center of the tank.Type: GrantFiled: October 12, 2007Date of Patent: July 7, 2009Inventors: Earle Schaller, Elaine Schaller
