Patent number: 10280926Abstract: Systems and methods for conditioning sewage having entrained solids which clog sewage pumps, are disclosed. Systems include a sewage pump, a chopper pump, and a mixing nozzle connected to the chopper pump. Specifically, the sewage pump is a non-clog centrifugal pump having an inlet for drawing fluid into the pump and an outlet for discharging the fluid into a pipe, while the chopper pump has an inlet for drawing fluid into the pump and an outlet for discharging the fluid into the wet-well. The chopper pump may be positioned either in or adjacent to the wet-well. The mixing nozzle fluidly coupled to the chopper pump discharge, is positioned in the wet-well. Methods include the steps of positioning a chopper pump within the wet-well, drawing in liquid sewage, including the entrained solids, reducing the size of entrained solids, and discharging the sewage and reduced size solids into the wet-well.Type: GrantFiled: May 23, 2016Date of Patent: May 7, 2019Assignee: VAUGHAN COMPANY, INC.Inventor: Glenn R.

Publication number: 20170043279Abstract: A surface foam diffuser and digester tank system prevents and/or suppresses the formation of foam during digestion. The system includes a first nozzle disposed above a top surface of the at least partially liquid contents, a splash plate positioned adjacent to the first nozzle outlet, and a second nozzle disposed below the top surface of the at least partially liquid contents for suppressing foaming in the large processing tanks. The system nozzles each have an inlet for receiving pressurized liquid and an outlet for ejecting a liquid stream into the tank, the depth of the second nozzle and the direction of the liquid stream there from being such that rotation of the top surface is facilitated. The spray of the first nozzle, as dispersed by the splash plate, reduces foam on at least a portion of the top surface, with the rotation of the top surface bringing each portion of the top surface to eventually fall within the reducing spray.Type: ApplicationFiled: October 27, 2016Publication date: February 16, 2017Inventors: Glenn R. Dorsch, Kent H. Keeran

Patent number: 7628183Abstract: A nozzle ejects a liquid stream generally horizontally inward from a location near the periphery of a tank, and fairly close to the upper surface of liquid in the tank. The liquid stream impinges on a splash plate or deflector to break the liquid stream into a reasonably uniform dispersion of droplets over a substantial area of the surface of the liquid in the tank, which reduces the surface foam.Type: GrantFiled: September 15, 2006Date of Patent: December 8, 2009Assignee: Vaughan Co., Inc.Inventors: Glenn R.
