In additional embodiments, the solids that have been disinfected by radiation are mixed with a suitable inert filler material to produce a soil substitute, fertilizer, compost, or other soil additive. The liquid phase is treated in a substantially smaller system than would be required for treating the full-strength wastewater that can include a suspended media biological regeneration reactor system.

  • Patent number: 8454802
    Abstract: A system for the production of ethanol and co-products is provided. The system facilitates an overall reduction in the use of energy, for example, by reducing the mass of wet solids supplied to a distillation system. The system also reduces the amount of energy used to dry the wet solids component of a fermentation product, for example, by increasing the ethanol concentration of the wet solids. The system also facilitates the recovery of co-products including bioproducts and other biochemicals extracted from components of the fermentation product. The solids component of the fermentation product may be dried and constituted into a meal that may be used for animal feed, among other uses.

  • Publication number: 20130126447
    Abstract: A filter configured to separate the solid components and the liquid components from a slurry. The filter includes a plurality of filter plate assemblies that cooperate to define a plurality of filter chambers, each defining a perimeter having an open section when the filter plates are in a closed position relative to one another. Each filter plate assembly includes a closure configured to close the open section. Preferably, the closures are movable to an open position to permit a particulate cake to be removed from the filter chambers without separating the filter plates.

  • Patent number: 8444851
    Abstract: The system is for the reception and transport of dry lime mud from a continuously operating pressurized filter in a causticization process. A tube valve is used as an outlet from the pressurized process. The tube valve has a minimum length that is twice a diameter of the tube. A column of lime mud can be held within it as a pressure lock. The column of lime mud can be caused to descend through the tube valve by controlling a difference in pressure between an inner surface and an outer surface of the tube such that the diameter of the tube expands essentially uniformly along its length by 5-10% or by at least 4-6 millimeters.

  • Patent number: 8372293
    Abstract: The invention concerns a process for the preparation of aqueous suspensions of fluid mineral matter, which are able to be pumped and conveyed by the end user immediately after the filtration stage, possibly followed by a compression, which process comprises filtration in two separate stages. The invention also concerns aqueous suspensions of mineral matter obtained and their uses.

  • Patent number: 8309711
    Abstract: The method of forming a filter cake from a slurry comprising the steps of feeding the slurry into a filter housing, wherein the filter housing includes a plurality of vertical filter elements; pressing the slurry into the filter housing against the filter elements resulting in i) a filtrate passing through the filter elements and exiting out an exhaust port of the filter housing; ii) forming a solid cake on the filter elements; feeding a wash liquid into the filter housing while draining out the slurry by opening the slurry drain valve; closing the slurry drain valve and then continually feeding wash liquid through the cake and into the filter tube of the filter housing; stopping the feed of wash liquid; introducing a gas into the filter housing and draining out the wash liquid by opening a bottom drain valve; stopping the gas flow and opening a drain to exit most of the gas and remaining wash liquid; opening the bottom cake discharge valve; and back pulsing by a gas to break and to release the filter cake fr

  • Patent number: 8282772
    Abstract: A method for processing wastewater includes the steps of introducing air and a liquid into a pump, and subjecting the air and liquid to high heat and pressure; delivering the heated and pressurized air and liquid from the pump to a gas and liquid separator to separate the air from the liquid; expanding the air from the gas and liquid separator through a nozzle to accelerate the air as it expands; injecting at least some portion of the wastewater to be processed into the air from the nozzle in an entrainment section downstream from the nozzle to entrain the wastewater into the air; passing the liquid portion from the gas and liquid separator through a valve to lower the pressure of the liquid to achieve flash evaporation of the liquid to produce water and steam; introducing the water and steam produced from the valve into the air and entrained wastewater in the entrainment section, to enhance entrainment of water into the air; and delivering the air and entrained wastewater from the entrainment section to an i

  • Patent number: 8262753
    Abstract: An apparatus suitable for generating gaseous hydrocarbon fuel from a carbon based synthesis gas including a reaction chamber having a rotating shaft including a plurality of radial blades mixing and circulating carbon based synthesis gas and particulate catalyst upwardly generating gaseous hydrocarbon fuel, a stripping chamber located above the reaction chamber having a second axial rotating shaft including a plurality of radial blades driving hydrocarbon fuel radially outwardly, a source of hot stripping gas, an annular filter surrounding the stripping chamber and an annular gas collection chamber surrounding the filter. The blades in the stripping chamber are rotated independently at a greater velocity than the blades in the reaction chamber and the reaction is controlled by the temperature of the synthesis gas and the rotational velocity of the mixing blades in the reaction chamber.
