  • Patent number: 11453607
    Abstract: A process for enhanced anaerobic digestion of sludge by alcoholization of food waste, comprising steps of: (1) ethanol prefermentation of food waste—feeding the food waste having been crushed into a uniform grain size into an ethanol production reactor, where the food waste is subjected to rapid and efficient anaerobic fermentation activated by addition of yeast and pH adjustment to produce ethanol and obtain a fermentation broth and a fermentation residue; (2) sludge pretreatment—pretreating the sludge after mixing with the fermentation residue; and (3) methanogenesis of anaerobic digestion—subjecting products resulting from the sludge pretreatment to be mixed with the fermentation broth and then to methanogenesis of anaerobic digestion in a methane production reactor. With this process, the sludge and the food waste can be treated efficiently via multi-phase reactions, and the resource recovery and biogas quality can be enhanced.

  • Patent number: 10513677
    Abstract: This disclosure may generally relate to a pressured vessel and, more particularly, to systems and methods for pressurizing a pressured vessel by producing a biogas using a recessed roof system. A pressured vessel may comprise a shell, wherein the shell may comprise a plurality of panels. The pressured vessel may further comprise a recessed roof and a deck. A method of collecting biogas from a pressure vessel may comprise disposing a liquid into the pressure vessel, disposing an anaerobic microorganism into the pressure vessel, adjusting a path of the biogas with a protruding baffle, collecting the biogas with the recessed roof, applying pressure to the outside of the recessed roof with the liquid such that the biogas pressure inside the recessed roof is increased, and removing the biogas from inside the recessed roof through a gas collection system.

  • Patent number: 10501352
    Abstract: A method is presented for biological removal of contaminants like sulfide from ground waters and industrial waters. A portion of the bioreactor effluent water is recycled to the bioreactor and the sulfide oxidizing bacteria by biological oxidation oxidizes sulfides in the water to produce soluble sulfates. The present invention uses a packed bed bioreactor configuration that uses packing material to maximize the concentration of sulfide oxidizing bacteria.

  • Patent number: 10501674
    Abstract: In order to substantially reduce friction during drilling operations, specialized lubricants need to be added to drilling fluid recipes. In general, lubricants reduce friction by forming a thin film of liquid that separates the solid surfaces in contact. The primary objective of this research is to evaluate the performance of enhanced activated sludge (EAS) as a lubricant in drilling fluids. EAS is activated sludge rich in lipids. The mixed consortium of microorganism in waste water treatment facilities in grown under a high carbon/nitrogen ratio to trigger lipid accumulation. Performance of EAS as drilling fluid additive was compared with commercial lubricants in terms of lubricity and flow properties. Lubricants were evaluated using water-based drilling mud at lubricant concentrations of 1.78, 3.11, 4.43, and 6.17 pounds per barrel (ppb). Experiments were carried out in a standard lubricity meter. The lubricity meter tests the ability of the lubricant in the drilling mud to reduce friction.

  • Patent number: 10479716
    Abstract: A Biorefinery System (BIOSYS) that effectively treats all human activity-derived waste (black water, grey water, and food waste streams) using biological systems and that produces as process by-products: recovered potable water, liberated free oxygen, edible protein cake (with and without lipids), soil amendments, and machinery lube oils. Additionally, the system captures and chemically binds carbon dioxide into microbial cells and associated by-products, thus producing recovered usable returned cabin air.

  • Patent number: 10384982
    Abstract: An organic waste material processing system includes a waste material holding tank and a slurry-producing device configured to process organic waste material into a slurry. A waste processing section has at least one pressurizeable tank connected to the waste material holding tank receiving slurry therefrom. The pressurizeable tank includes a slurry temperature adjusting part and a first hydrocarbon capturing structure configured to capture hydrocarbon vapors produced by the slurry at a predetermined temperature. A hydrocarbon vapor processing section collects captured hydrocarbon vapors from the waste processing section such that an electric power producing apparatus generates electricity using collected hydrocarbon vapor and provides electric power to at least the pretreatment section and the waste processing section. A waste post-processing section is configured to receive processed slurry produce salable organic materials, nutrient enhanced media and recycled water.

  • Patent number: 10344303
    Abstract: A low-cost process is provided to render lignocellulosic biomass accessible to cellulase enzymes, to produce fermentable sugars. Some variations provide a process to produce ethanol from lignocellulosic biomass (such as sugarcane bagasse or corn stover), comprising introducing a lignocellulosic biomass feedstock to a single-stage digestor; exposing the feedstock to a reaction solution comprising steam or liquid hot water within the digestor, to solubilize the hemicellulose in a liquid phase and to provide a cellulose-rich solid phase; refining the cellulose-rich solid phase, together with the liquid phase, in a mechanical refiner, thereby providing a mixture of refined cellulose-rich solids and the liquid phase; enzymatically hydrolyzing the mixture in a hydrolysis reactor with cellulase enzymes, to generate fermentable sugars; and fermenting the fermentable sugars to produce ethanol. Many alternative process configurations are described.

  • Patent number: 10336633
    Abstract: Processes and systems for maintaining a live culture of activated sludge in the activated sludge unit of a petroleum refinery during an extended refinery shut-down. In the absence of a source of refinery wastewater, a living culture of activated sludge comprising aerobic prokaryotes and/or eukaryotes that nitrify ammonia is maintained by redirecting at least a portion of clarified wastewater leaving the clarifier portion of an activated sludge unit. The redirected clarified wastewater is mixed with an organic food source that may be ammonia and/or ethyl acetate, a source of phosphate ion, and the pH is adjusted to produce a growth media that is returned to the aeration chamber of the activated sludge unit. After a time exceeding one week, the input of refinery wastewater to the aeration chamber is resumed while discontinuing the redirecting of the clarified wastewater.
