Patent number: 7794609Abstract: Apparatus and methods are provided for controlling influent feed to produce a substantially uniform flow to a clarifier tank (2) to thereby enhance the settling efficiency within the clarifier. The apparatus comprises a feedwell (24) having a roof (26) and continuous sidewall (28) that together define a feedwell main body enclosure. Influent is fed via a relatively inboard tangential feed mechanism (108) to the inside of the roof (26) from an entry point proximate the center of the roof (150). Influent energy is properly distributed via the action of centrifugal force to generate a uniform axial flow within the feedwell main body which, in turn, is fed into the clarifier tank. Optional baffle members (152, 158) may be provided in the housing to slow angular momentum of the influent which, due to its original feed location, would necessarily be at a relatively low level.Type: GrantFiled: November 1, 2006Date of Patent: September 14, 2010Assignee: Kadant Black Clawson Inc.Inventor: John J.

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

Patent number: 7637379Abstract: The improved circular secondary clarifier of the present invention requires less surface area and low HRT and provides efficient solids-liquid separation. The improved clarifier has better SS and BOD reduction and provides high under flow solids concentrations, as compared to conventional secondary clarifiers. The improved clarifier is even capable of treating wastewaters containing low MLSS concentration. One of the biggest advantages of improved clarifier is that it does not require a separate sump cum pump house as it removes the settled sludge using suction mechanism thereby reduces capital and recurring cost. Further, it provides natural flocculation, which is essential for agglomeration of solids and increases particle size referred to as ‘floc’ and eliminates provision for a separate flocculation facility thereby reduces capital and recurring costs.Type: GrantFiled: November 6, 2007Date of Patent: December 29, 2009Assignee: Council of Scientific & Industrial ResearchInventors: Girish Ramesh Pophali, Tapas Nandy, Santosh Narain Kaul, Sukumar Devotta

Patent number: 7479231Abstract: A method and apparatus for separating mixtures of fluids having different densities. According to one aspect of the invention, a lower density fluid is separated from a higher density fluid. A mixture of the two fluids is received in a tank. A centrifugation of the mixture is induced in the tank. The lower density fluid is evacuated from the tank until the level of an interface created at least in part by the centrifugation between the higher density fluid and the lower density fluid reaches a predetermined threshold.Type: GrantFiled: May 4, 2005Date of Patent: January 20, 2009Inventor: Robert H. Bernard

Patent number: 7445704Abstract: An above ground oil and water separator including a pump to draw potentially contaminated water from a containment area, and to supply a flow of water to an enclosure. An enclosure inlet pipe takes water from the diaphragm pump into the enclosure. A first sub-enclosure is formed within the enclosure by a wall containing a plurality of coalescing spheres. The coalescing spheres are bagged within the first wall and can be removed through an external lid during cleaning and removal of coalesced oil. A heat source contained within an electrical panel heats water and supplies the heated water to the enclosure to prevent freezing within the enclosure.Type: GrantFiled: February 23, 2007Date of Patent: November 4, 2008Inventor: Roy W. Jorgensen

Patent number: 7435864Abstract: Disclosed is a device for the production of alkylate(s) by sulfuric acid alkylation of at least one isoparaffin such as isobutane with at least one olefin, such as butylenes. The device includes a mixing chamber for preparing a mixture of the isoparaffin with recycled reaction products. It also includes an emulsion chamber for preparing a first hydrocarbons-in-sulfuric acid emulsion, where the mixture prepared in the mixing chamber is injected in multiple parallel jets into a sulfuric acid composition. The device further includes a pre-reaction chamber for preparing a second emulsion, where a given portion of the olefin is injected in jet streams into the first hydrocarbons-in-sulfuric acid emulsion coming from the emulsion chamber.Type: GrantFiled: June 1, 2001Date of Patent: October 14, 2008Assignee: Orgral International Technologies CorporationInventor: Semen Gershuni

Publication number: 20080245728Abstract: An oil-water separation pack includes an upper body having cross-sectional shape narrowing from a bottom to a top. The upper body includes an oil rising region provided in an inside central portion thereof, and an oil-discharging opening provided in a top portion thereof. A lower body disposed beneath the upper body includes a plurality of oblique flow-in ports, which allow an oil-water mixture to flow obliquely into an inside portion thereof and flows of the oil-water mixture to collide with each other and stagnate in the inside portion of the lower body, thereby enabling the oil to float and be separated from water. A coupling unit integrally couples a bottom portion of the upper body with a top portion of the lower body, thereby forming a continuous space extending from the lower body to the upper body. The continuous space allows oil to float therethrough.Type: ApplicationFiled: September 6, 2007Publication date: October 9, 2008Inventor: Cheon Eok Lee
