Patent number: 7491322Abstract: A method of and system for removing phosphorus from wastewater using a waste sludge that has a high affinity for phosphorus. In order for the waste sludge to be used in a flow-through contact reactor to remove the phosphorus from a wastewater stream, the waste sludge is pelletized. The waste sludge pellets are packed into one or more flow-through contact reactors. In the configuration described herein, phosphorus removal is maximized by flowing the wastewater through the reactor(s) in a “pulsed” manner, rather than continuously. Thus, wastewater is flowed through the reactor(s) for a period of time and stopped for a period of time. By giving the sludge absorbant a rest period, the absorption capacity of the sludge is increased significantly, thus decreasing the frequency of regeneration or replacement of the sludge. Sludge regeneration can be accomplished with a stripping step using an alkaline solution of pH 13, followed by rinsing with water.Type: GrantFiled: October 1, 2007Date of Patent: February 17, 2009Assignee: The United States of America as represented by the Secretary of the InteriorInventor: Philip L.

Patent number: 7491321Abstract: Contaminants are removed from fluid in a system where the fluid is sprayed into an air head at the top of a tank through a diffuser and withdrawn through a pick-up tube. A solenoid valve operates to allow oxygen-containing gas from a compressed gas source to flow into the tank through a shuttle valve, which is opened by the gas pressure. Simultaneously, a drain valve connected to the shuttle valve opens a drain, venting water and air from the tank. The solenoid valve also operates to close the gas supply line and connect the shuttle valve through a vent to atmosphere. Pressure within the tank closes the shuttle valve, which in turn closes the drain valve and disconnects the shuttle valve from the tank. A one-way-flow valve prevents fluid or gas from flowing from the tank backwards through the shuttle valve to the solenoid valve and out the vent.Type: GrantFiled: July 18, 2006Date of Patent: February 17, 2009Assignee: Hellenbrand, Inc.Inventors: Edward T.

Patent number: 7314546Abstract: A system for the chemical treatment of wastewater may be discharged in a night spray system, an on demand system or a dosing system. Tank 12 receives wastewater, and a discharge pump 16 pumps wastewater from the tank in the night spray system. A sensor 24 deactivates the discharge pump when the wastewater level reaches a predetermined low level, and in some applications activates the discharge pump when the wastewater level reaches a predetermined high level. A liquid disinfectant pump 38 pumps liquid disinfectant to the tank, and a controller 30 activates a liquid disinfectant pump for a selected time interval as a function of the discharge system.Type: GrantFiled: June 11, 2004Date of Patent: January 1, 2008Assignee: Jerry L. McKinney 2002 TrustInventor: Jerry L. McKinney

Patent number: 7300569Abstract: A water treatment system which includes a control valve with a venturi for drawing air into a tank. The passage of untreated water into the control valve draws air into a tank for oxidation of the water. The flow of the air into the tank is independent of the flow of treated water from the system.Type: GrantFiled: May 10, 2004Date of Patent: November 27, 2007Assignee: New Aqua, LLC d/b/a Agua SystemsInventor: Bret L. Petty

Patent number: 7276169Abstract: A method for filtering the water of an aquarium, a water cultivation tank or similar water bonds, by means of a filtering system comprising a closed vessel and defining a chamber, a filtering body housed in the chamber, a circulation pump having a suction duct, communicating with the aquarium by interposition of a siphon and a delivery duct communicating with the aquarium. Vent means are also provided to eject the air from the chamber. The method comprises the steps of: filling the filtering body with a predetermined amount of water; starting the pump; short-circuiting the pump by means of a fluid passage by putting the delivery duct in communication with the closed vessel; keeping the pump short-circuited at least up to determine the siphon trigger; subsequently stopping the pump; keeping the pump stopped to allow the air to escape from the chamber and the filtering body to be filled with water; re-starting the pump.Type: GrantFiled: April 4, 2005Date of Patent: October 2, 2007Assignee: Askoll Holding S.r.l.Inventor: Elio Marioni

Patent number: RE40310Abstract: A water purification system for purifying water flowing through a water flow path. The system includes a water purification device having an inlet and an outlet in the water flow path and at least one interior volume communicating with the inlet and outlet. A purification medium is disposed within the interior volume of the water purification device. A flow control system is provided controlling a volume of purified water dispensed from the outlet. The flow control system includes an input device configured to allow a user to input a desired volume of purified water to be dispensed from the outlet and a sensing device coupled with the electronic input device and operative to determine the volume of purified water being dispensed from the outlet. A flow regulation device is coupled with the flow control system and operative to stop the discharge of purified water at the outlet upon reaching the desired volume of purified water.Type: GrantFiled: May 3, 2004Date of Patent: May 13, 2008Assignee: Barnstead Thermolyne CorporationInventors: Thomas J. Larkner, Steven C. Peake, Chester E. Chomka, Joseph F. Tilp, Eric J. Willman, Kerry W. Leppert, Tina M. Timmerman
