Patent number: 12064714Abstract: Sand and liquid that are stored within a hopper are pulled together along a trough by a set of discs that are attached to and rotate about a shaft. The trough is configured to allow the liquid to flow downwards as the sand is compacted and elevated.

Patent number: 11912592Abstract: A continuous flow granular/flocculent sludge wastewater process selects for granule biomass capable of nitrogen and phosphorus removal and controls granule size and concentration of granular and flocculent sludge for optimal nutrient, organic, and solids removal in a smaller footprint. A series of biological process zones lead to a secondary clarifier. Mixed liquor sludge, preferably from an aerobic zone, goes through a classifier or separator processing flow from the aerobic zone, to the secondary clarifier. In a sidestream process that can be included a portion of sludge preferably from an aerobic zone goes through a classifier or separator to selectively produce a granular-rich effluent, and the clarifier may also have a separator to further concentrate granular biomass, most of which is cycled back to an initial multi-stage anaerobic process zone. The anaerobic zone is structured and operated to encourage growth of granules in subsequent process zones.Type: GrantFiled: August 20, 2021Date of Patent: February 27, 2024Assignee: Ovivo Inc.Inventors: Hiren Trivedi, John Vorwaller, Tyson Beaman, Sophia Baker, Sergio Pino-Jelcic, David Stensel

Patent number: 11787720Abstract: Organic solid waste is pressed at a high pressure to separate the solid waste into a dry fraction and a wet fraction. The wet fraction is diluted and floatables (i.e. pieces of plastic and/or paper) in the wet fraction are comminuted. The wet fraction is then de-gritted before being sent to an anaerobic digester. Digestate is withdrawn from the digester from a free liquid surface of the digester. The digestate is filtered to extract comminuted floatables. The resulting filtrate is then composted or directly applied to land. A corresponding system comprises a press, a grinder, a hydrocyclone, an anaerobic digester, a filter and a dewaterer.Type: GrantFiled: February 20, 2019Date of Patent: October 17, 2023Assignee: ANAERGIA INC.Inventors: Andrew Benedek, Juan Carlos Josse

The apparatus includes a first container for receiving solids and fluid and a second container adjacently disposed to the first container in fluid communication therewith. The apparatus includes a conveying member extending upwardly from the bottom of the first container and angling upwardly through the second container such that the conveying member transports solids that settle to the sloped bottom portion of the first container from the first container and through the second container. A conveyor member housing may be disposed in the second container so as to provide an enclosure about the conveyor member to prevent solids that are being transported through the second container by the conveyor member from being deposited into the second container while permitting fluid that separates from the solids during transport to pass from the conveyor member housing and into the second container.Type: GrantFiled: December 15, 2008Date of Patent: February 19, 2013Assignee: 4 M Welding, Inc.Inventor: Thomas D. Miller

Patent number: 8273302Abstract: A component separating device includes a flow channel, an acoustic wave generator for generating an acoustic wave in the flow channel, a first inlet channel for introducing a fist solution containing solid particles into the flow channel, a second inlet channel for introducing a second solution, and outlet channels for discharging a solution from the flow channel. A density grade generator is provided at the first inlet channel for forming a density grade of the solid particles. This component separating device extracts the solid particles into a high-purity solution at a high collecting rate.Type: GrantFiled: May 14, 2008Date of Patent: September 25, 2012Assignee: Panasonic CorporationInventors: Makoto Takahashi, Masaya Nakatani, Soichiro Hiraoka, Hiroshi Ushio, Akiyoshi Oshima

Publication number: 20120125827Abstract: A device for separating components of a mixture, particularly industrial fluids but also gases including air, allows for targeted components of the mixture to be attached onto a separating bar and removed from the mixture. The separating bars traverse a track formed within the body of the separating device and through respective tank, cleaning, free roll, and compression regions in a controlled cleaning system. The separating bars are detached from one another and allowed to move through the separating device independently of one another. The device removes the use of chains to connect cleaning bars traversing through a cleaning system.Type: ApplicationFiled: November 24, 2010Publication date: May 24, 2012Inventors: Richard E. Fogel, Brent D. Terrell

Patent number: 8182700Abstract: A method and exhaust arrangement in the removal of surface scum. An exhaust arrangement is used existing in connection with a liquid basin. The exhaust arrangement includes a first surface chute arrangement for removal of surface scum utilizing an overflow arrangement, belonging to the first chute arrangement and being based on a continuous flow for overflowing the surface scum in at least two successive phases, from the fluid basin into a primary space in the fluid basin and from the primary space into a secondary space in the fluid basin, from where overflow is finally exhausted from the liquid basin utilizing an exhaust assembly for the surface scum. A second surface chute arrangement removes liquid processed in the liquid basin.Type: GrantFiled: July 15, 2008Date of Patent: May 22, 2012Assignee: Finnketju Invest OyInventor: Pekka Tuomikoski

Publication number: 20120012540Abstract: A grit removal system for tanks with a need to remove settled solids (e.g., anaerobic digester tank) is described. The system is especially suitable for a large tank, preferably having a flat floor, and it works well while submerged under a liquid. Specifically, a periphery-driven rack & pinion mechanism drives a shaft to rotate about a center pivot, and scrapes settled solids towards tank periphery, where the solids fall into a pit on the tank floor. A drainage opening inside the pit, when opened by a valve, is used to flush out the solids through a standpipe into a settlement tank for final dewatering and solid disposal. The system is compatible for continuous tank operation, and is useful for stirring tanks requiring periodic sediment removal.Type: ApplicationFiled: July 14, 2011Publication date: January 19, 2012Inventors: Peter Kotelko, Mike Kotelko, George Caraganis, Glen Foster

Patent number: 8075785Abstract: A separation device for removing solids from an input stream is provided, comprising a vessel, such as a production vessel or storage tank, having an inlet for receiving an input stream containing fluids, such as oil and water, and solids, such as sand and silt. The vessel also includes a fluid outlet and a drain outlet. An optional fluid recirculation and injection device is mounted inside the vessel and delivers fluid to facilitate removal of the solids through the drain outlet. The vessel also includes an agitation or flighted device mounted adjacent to the drain outlet for contacting and dislodging solids which have settled within the vessel. The agitation device includes a rotatable shaft driven by a motor, and an agitation element, such as an auger, to break up the solids and move them toward the drain outlet. A method of removing solids is also provided using the auger device.Type: GrantFiled: May 22, 2009Date of Patent: December 13, 2011Assignee: Omni Energy Services Corp.Inventors: Andy Dufrene, Joey Jacob, Vincent Spekschate, Eddie Boudreaux, Brian Fontenot
