  • Publication number: 20250230085
    Abstract: A system for dewatering a material comprising a slitter, wherein the slitter receives the material, separates the material into a plurality of clumps, and deposits the plurality of clumps of material substantially evenly on a conveyor belt. The conveyor belt is partially porous to allow water to pass through but preventing material from passing through. The conveyor belt is operable to convey the material from the slitter to a compression zone; the compression zone comprises at least one high pressure press. The compression plates engages the material positioned on the conveyor belt. At least one knife positioned proximate the at least one compression plate operable to remove material from the bottom surface of the at least one compression plate after a compression cycle; and at least one drain positioned under the conveyor belt to carry water removed from the material away from the conveyor belt.

  • Publication number: 20250187999
    Abstract: This invention discloses and claims a system comprising greenhouses for receiving biosolids comprising a heated slab and an odor control system; a pasteurization building to receive the biosolids from the greenhouse, at lease one pasteurization system comprising heat up belts, a burner fan to heat the biosolids, a pasteurization belt to convey the biosolids through a pasteurization chamber; holding tanks to receive the biosolids and enhancement storage to hold enhancements, a scale and a blender to blend the biosolids with the one or more enhancements, a pellet mill to receive a blended fertilizer, the pellet mill comprising a die to form the blended fertlizer into a pellet and a knife to cut the pellet to a desired length, wherein the pellet mill further comprises a temperature-controlled die operable to control the temperature of the blended fertilizer to promote the formation of the pellets.

  • Patent number: 12291492
    Abstract: A system for reducing particles from biosolids, comprising a storage tank for holding biosolids and an inlet pipe. The inlet pipe delivers biosolids from the storage tank to a screener and then to a percent solids meter. The percent solids meter measures the solid content in the biosolids and sends a signal to an electronic solenoid valve to control water content of the biosolids introduced to the system. A first venturi hydrodynamic cavitation to create vacuum bubbles in the biosolids. A mechanical hydrodynamic cavitation device operably connected to first venturi hydrodynamic cavitation, wherein the mechanical hydrodynamic cavitation device creates vacuum bubbles in the biosolids.

  • Patent number: 11999668
    Abstract: A system for converting biosolids to fertilizer comprising: a storage tank for holding biosolids; a conveyor operably connected to the storage tank for conveying the biosolids from the storage tank to a pressurized screener, wherein the pressurized screener selectively eliminates unwanted debris from the biosolids; a second conveyor operably connected to the pressurized screener to convey the biosolids to a centrifuge, the centrifuge operatively configured to remove water from the biosolids; a third conveyor operably connected to the centrifuge to convey the biosolids to a feeding chamber, a self-leveling conveyer position in the feeding chamber configured to deliver the biosolids to a nip feeder operatively positioned in the feeding chamber to selectively biosolids from the feeding chamber to a nip, wherein the nip is a gap between a first and second dryer drums; the first and second dryer drums operatively positioned to rotate and draw biosolids from the nip feeder into the nip, wherein a first and second s
