The present disclosure relates to a dewatering systems, and related methods, that are adapted to convey lignocellulosic biomass to separate at least a portion of the water from a lignocellulosic biomass slurry and accumulate the dewatered lignocellulosic biomass. The dewatering system also includes a headspace occupied by a gas that is at a pressure that facilitates transferring the accumulated biomas into a pretreatment reactor having a pressurized headspace. Such a dewatering system can prevent undue mixing and backflow of gas (e.g., steam) from the pretreatment reactor.

The present disclosure is directed to a method of removing pesticides from water. An electrolysis cell oxidizes pesticides and/or other organic components, optionally in conjunction with one or more filtration steps. Hydrogen peroxide may be added to the electrolysis process to aid oxidation.

A wastewater treatment method and system based on inoculating a bioreactor at startup with an integrated methanogenic aerobic single sludge with no additional inoculations thereafter to achieve anaerobic, aerobic, and/or anoxic treatment of industrial or municipal wastewater.

A process for treating rice bran utilizing a shear pump to circulate a solution comprising an enzyme, an acid and water with rice bran in a mixing tank, then after a first predetermined period transferring a portion of the solution to a feed tank, and then over a second predetermined period filtering the solution in the feed tank through multiple filtration units each having a pre-selected pore size to obtain pre-determined value-added by-products from the rice bran.

An assembly line grow pod includes a track extending between a growing region and a sanitizing region, a cart movably engaged with the track, a sanitizer system that applies a sanitizer solution to the cart at the sanitizing region, the sanitizer system including a gray solution tank for storing sanitizer solution runoff collected from the sanitizing region, a watering system that provides water to plant matter on the cart at the growing region, the watering system including an untreated water tank for storing water runoff collected from the growing region, and a flowmeter fluidly coupled to at least one of the sanitizer system and the watering system.

An efficient, cost-effective, and efficacious technique for removing coal ash and other pollutants from waterways, ponds, marshes, holding tanks and other water sources and supplies. An apparatus comprising an open cage including electromagnets and/or permanent magnets and/or electrodes is supplied with electrical power to extract materials such as rare earth elements and/or heavy metals. The materials levitate to the surface, forming a slurry while leaving water substantially free of such materials. Rare earth magnets electrically connect electrolysis electrode structures and serve as electrolysis electrode segments.

The invention relates to a novel dry-state anaerobic digestion method comprising pretreatment of the input with an additive selected from among zeolite, clay, pozzolan and biochar.

Devices, systems and methods for using photosynthetic biomass to purify water, reduce indoor air pollution, remove greenhouse gases including CO.sub.2 from outdoor atmospheric air, and produce biofuel, food products, and fertilizer are provided herein. Also provided herein are systems and methods for enhancing growth of a photosynthetic biomass in a greenhouse.

Fusion proteins containing a targeting sequence, an exosporium protein, or an exosporium protein fragment that targets the fusion protein to the exosporium of a Bacillus cereus family member are provided. Recombinant Bacillus cereus family members expressing such fusion proteins are also provided. Genetically inactivated Bacillus cereus family members and recombinant Bacillus cereus family members that overexpress exosporium proteins are also provided. Seeds coated with the recombinant Bacillus cereus family members and methods for using the recombinant Bacillus cereus family members (e.g., for stimulating plant growth) are also provided. Various modifications of the recombinant Bacillus cereus family members that express the fusion proteins are further provided. Fusion proteins comprising a spore coat protein and a protein or peptide of interest, recombinant bacteria that express such fusion proteins, seeds coated with such recombinant bacteria, and methods for using such recombinant bacteria (e.g., for stimulating plant growth) are also provided.

A method of scale inhibition treatment of a water system comprising introducing an aqueous scale inhibiting composition into the water system wherein the aqueous scale inhibiting composition comprises a carboxylated hyperbranched polyglycerol.
