Patent number: 6797181Abstract: To optimally mix treatment additives to a contaminated liquid, treatment additives are selected. A mixing energy requirement of the contaminated liquid and treatment additives is then determined by mixing the treatment additives over a range of time and mixing speeds, and measuring turbidity to determine the mixing time and speed which results in the lowest turbidity. A low mixing energy requirement requires a lower mixing time and mixing speed than a higher mixing energy requirement. The contaminated liquid and selected treatment additives are then directed into a mixing system including at least one hydrocyclone. Each hydrocyclone has an inlet aspect ratio, a barrel length and diameter selected based upon the mixing energy requirement determination. Altering the aspect ratio, diameter, and length of the hydrocyclone results in different mixing speeds and mixing time, which can be optimized for the given contaminated liquid and treatment additives.Type: GrantFiled: October 14, 2002Date of Patent: September 28, 2004Inventors: Dwain E. Morse, Wade O. Morse, Thomas G. Matherly

Patent number: 6790349Abstract: A waste treatment apparatus for the treatment and processing of wet material is provided. The apparatus comprises an inlet hopper adapted for receipt of the wet material. A pre-conditioning unit is provided having an input and an output end wherein the wet material is received from the inlet hopper at the input end and is conveyed to the output end wherein the wet material is processed to reduce moisture and pathogen content. A blower is provided for providing a forced air stream to direct the flow of the wet material and for directing the flow from the output end of the pre-conditioning unit. A pre-separation cyclone is provided and is operatively positioned for receiving the wet material from the output end of the pre-conditioning unit via the air stream powered by the blower, wherein the wet material is processed under the influence of cyclonic forces that further reduce the moisture content, pathogen content, and reduce the particle size of the wet material.Type: GrantFiled: May 5, 2003Date of Patent: September 14, 2004Assignee: Global Resource Recovery Organization, Inc.Inventor: Bud Sawyer

Patent number: 6767459Abstract: Fluid processing apparatus comprising a vessel containing a hydrocyclone and defining an inlet chamber, the vessel having a vessel inlet arranged to feed fluid into the inlet chamber, being arranged to receive fluid from the vessel inlet and to pass the fluid to an inlet of the hydrocyclone. The inlet chamber includes coalescing means arranged to coalesce relatively small droplets contained in the fluid received at the vessel inlet into larger droplets before passing the fluid to the hydrocyclone inlet. The coalescing means having a substantially predetermined external shape which defines at least one elongate liner hole for receiving a respective hydrocyclone liner.Type: GrantFiled: January 9, 2002Date of Patent: July 27, 2004Assignee: Cyclotech LimitedInventors: Alastair Brenton Sinker, Michael James Hess, David Andrew Hadfield

Publication number: 20040140273Abstract: An apparatus is provided for separation of suspended solid particles from fluids, for separation and mixing of fluids, and for dissolving gases in aqueous fluids. The apparatus employs a grooved ring to divide the fluid stream and impart a high velocity on each of the divided or sub-streams. A grooved ring with any number of grooves that may be spiral in shape is used to create a high velocity circular motion on a divided stream for separation of suspended solid particles by centrifugal force in a cyclone filter and for saturation of liquid with gases in a fluid mixer where gases are introduced through a diffuser. A grooved ring with any number of grooves that may be radial is used in a fluid mixer to divide a stream of fluid, produce a high velocity flow through each groove, introduce a second fluid through an orifice into the first fluid flowing through each groove, and direct the fluid mixture to a center impact zone where the various streams collide to complete the mixing.Type: ApplicationFiled: November 18, 2003Publication date: July 22, 2004Applicant: Hydrotreat, Inc.Inventor: Johnny Arnaud

Publication number: 20040124136Abstract: An apparatus and a method for treating water or other liquid material and a guide plate for use in a tube An apparatus for treating water or other liquid material comprises a tubular element and a guide plate. The tubular element has an outer circumferential wall defining a through going passage therein and defining an inlet end and an outlet end. The guide plate is of an elongated configuration defining a longitudinal axe and is sidewise twisted one turn relative to the longitudinal axis. The guide plate is receivable within the passage for separating the passage into two parts for guiding water or other fluid material along the two parts of the passage from the inlet to the outlet end in one side wise turn.Type: ApplicationFiled: October 23, 2003Publication date: July 1, 2004Inventor: Jorgen Bak
