The system is generally a continuous flow system including a multi-stage cavitation device, an electrocoagulation device, and an air flotation unit. The electrocoagulation device includes a plurality of interweaved cathode and anode plates. The anode plates are coated with an oxygen generating mixed-metal oxide coating. The air flotation unit includes a cavitation aerator and electrode blocks to introduce air bubbles into the fluid. Contaminants attach to the air bubbles and float to the fluid surface where they are removed as sludge. Treated fluid is passed through a final filtration system. The methods involve the processes imparted by the various apparatuses on the fluid.Type: ApplicationFiled: January 7, 2014Publication date: May 1, 2014Applicant: CAVITATION TECHNOLOGIES, INC.Inventors: Roman Gordon, Igor Gorodnitsky, Maxim A.

Publication number: 20140097130Abstract: A valve arrangement includes various improvements useable in the context of a fluid additive system, such as a water softener. For example, the valve assembly may include a seal assembly engaged by a reciprocating piston, in which the seal assembly includes a minimal number of parts, is easily assembled, and can be easily inserted in the bore of the valve body without jeopardizing the integrity of the seals. The valve assembly may further include a quick-disconnect system which allows a “control head” including a valve actuation system and electronic controls to be disconnected from the rest of the valve arrangement with only a partial rotation of the control head. The valve assembly may also include a venturi used for drawing regeneration fluid into the system, and an associated venturi cleaner system which allows a user to unclog the fluid-flow orifice of the venturi without any disassembly of parts of the valve arrangement.Type: ApplicationFiled: March 15, 2013Publication date: April 10, 2014Inventors: Rudy B. Wilfong, Robert D. Rohr

Patent number: 8685236Abstract: A method of removing contaminates from sour water is provided. The method includes producing raw sour water within a syngas production system, and removing the contaminates from the raw sour water using a chemical reaction within a treatment unit to produce treated sour water. The treatment unit is in flow communication with the syngas production system.Type: GrantFiled: August 20, 2009Date of Patent: April 1, 2014Assignee: General Electric CompanyInventor: Gary Daniel Miller

Patent number: 8685237Abstract: An improved draft tube spout fluid bed (DTSFB) mixing, handling, conveying, and treating apparatus and systems, and methods for operating are provided. The apparatus and systems can accept particulate material and pneumatically or hydraulically conveying the material to mix and/or treat the material. In addition to conveying apparatus, a collection and separation apparatus adapted to receive the conveyed particulate material is also provided. The collection apparatus may include an impaction plate against which the conveyed material is directed to improve mixing and/or treatment. The improved apparatus are characterized by means of controlling the operation of the pneumatic or hydraulic transfer to enhance the mixing and/or reacting by controlling the flow of fluids, for example, air, into and out of the apparatus. The disclosed apparatus may be used to mix particulate material, for example, mortar; react fluids with particulate material; coat particulate material, or simply convey particulate material.Type: GrantFiled: November 6, 2009Date of Patent: April 1, 2014Assignee: Rensselaer Polytechnic InstituteInventors: Howard Littman, Joel L. Plawsky, John D. Paccione

Publication number: 20140076810Abstract: Methods and systems for use of switchable water, which is capable of reversibly switching between an initial ionic strength and an increased ionic strength, is described. The disclosed methods and systems can be used, for example, in distillation-free removal of water from solvents, solutes, or solutions, desalination, clay settling, viscosity switching, etc. Switching from lower to higher ionic strength is readily achieved using low energy methods such as bubbling with C02, CS2 or COS or treatment with Bronsted acids. Switching from higher to lower ionic strength is readily achieved using low energy methods such as bubbling with air, inert gas, heating, agitating, introducing a vacuum or partial vacuum, or any combination or thereof.Type: ApplicationFiled: December 15, 2011Publication date: March 20, 2014Applicants: Greencentre Canaga, Queens's UniversityInventors: Philip G. Jessop, Sean M. Mercer, Tobias Robert, R. Stephen Brown, Timothy James Clark, Brian Ernest Mariampillai, Rui Resendes, Dominik Wechsler

Patent number: RE44920Abstract: A system for collecting, treating and disposing of waste fluid includes a station that features transfer, flushing and mixing pumps as well as a bowl that holds the waste fluid. The waste fluid is collected in a container mounted on a cart. The cart container connects to the station so that the waste fluid is transferred from the cart to the station bowl by the transfer pump. The flushing pump has an inlet that communicates with a source of water and a disinfectant dispenser. The flushing pump is used to flush both the cart container and the station bowl, the latter of which communicates with a drain system. The flushing pump also delivers disinfectant to the waste fluid in the station bowl. The inlet and outlet of the mixing pump communicate with the bowl so that it mixes the bowl contents. Buffer is provided to the circulating waste fluid until the pH level drops to a predetermined level.Type: GrantFiled: February 21, 2013Date of Patent: June 3, 2014Assignee: Dornoch Medical Systems, Inc.Inventors: James L. Dunn, Lawrence E. Guerra
