Embodiments of the present disclosure can include a method for isolating a contaminate from water comprising: introducing a plurality of aluminum-doped nanoparticles to water, the water comprising the contaminate; contacting the plurality of aluminum-doped nanoparticles with the contaminate to form contaminate-adsorbed nanoparticles; and isolating the contaminate-adsorbed nanoparticles by applying a magnetic field to the water.

A method for differentially lysing a liquid sample or target material using an augmented oxidizing agent (AOA), which includes a quantity of electronically modified oxygen derivatives (EMODs). The method reduces or eliminates total dissolved solids (IDS), total suspended solids (TSS), Biologic Oxygen Demand (BOD), microbial concentration, biofilms and other content in the liquid target material known or suspected to contain animal fluids, blood and blood cells and suspected or known to contain eukaryotic cells, microbial cells, bacteria, viruses, spores, fungi, prions, organic matter, minerals, proteins or associated structures. The BOD, TDS and TSS can be lowered or eliminated as desired. This action is directly proportional to the quantity of EMODs in the AOS applied to the liquid target material.

A waste stream is treated by anaerobic digestion. A process is described involves a step of separating solids from digestate, and returning separated solids to a digester. Optionally, there may be a step of solids separation in which larger solids are removed from the digester. A process and apparatus are described for treating waste sludge from a wastewater treatment plant in an anaerobic digester. Feed sludge is thickened or solids are separated from digestate and returned to the digester. Additional co-digestion waste may be added to the digester. The process and apparatus may be used in a retrofit of an existing wastewater treatment plant.

Methods of modifying renewable protein sources and uses thereof are provided. In some embodiments, renewable protein sources can be modified to become a flocculant and/or coagulant through the use of a hydrolysis process. Further modifications can be performed in order to enhance the flocculant/coagulant ability of the modified protein material. Such modified protein material can be used to coagulate and/or flocculate waste water colloidal suspensions, either alone or in combination with a coagulant, by mixing the modified protein material with waste water colloidal suspensions to create a mixture and allowing mixture to settle. In some embodiments, the waste water colloidal suspension can be mature fine tailings (MFT).

Disclosed is an enzymatic hydrolysis device for livestock and poultry slaughter by-products, including a feeding barrel, and a crushing box is fixed and communicated with a bottom end of the feeding barrel; two symmetrically arranged rolling plates are arranged in the feeding barrel, and a rolling space is arranged between the two rolling plates, and a bottom of the rolling space is provided with a bearing plate; an air pump is fixed at a bottom of the crushing box; and a mixing disturbance mechanism, including a bottom plate, a slide rail fixed on a top surface of the bottom plate, a tank body slidably connected to the slide rail, and baffles fixed at both ends of the bottom plate; the tank body is internally provided with a plurality of circumferentially distributed curved panels; and there are a plurality of circumferentially distributed disturbance components in the disturbance space.

A method and an apparatus for maintaining a stable microbial community in a combined anaerobic-aerobic waste processing system. The system comprises cycling of waste activated sludge between reactors, thereby ensuring a healthy microbial community and an efficient waste decomposition.

The present invention provides for a multi-stage water treatment system for a plurality of aqueous solutions generated in municipal and industrial processes, e.g., oil and gas field operations, poultry processing, meat processing, dairy processing, and mineral extraction among others. A sequence of different processing steps is carried out, based on the characterization of the composition of contaminants present in the water to be treated. The steps to be carried out include chemical reaction in a series of reactor tanks, sedimentation in slanted plates chamber, air flotation and disinfection, hydrocarbon recovery by a scraper located in a flotation cell. A series of conventional methods are selected to be applied in series for the removal of the contaminants. The process design of an integrated chemical reaction, sedimentation and oxidation system to be used in water treatment of aqueous effluents is presented which is suitable for municipal and industrial processes.

A disinfectant composition useful in shrimp aquaculture and a process for using such a disinfectant, in which there is a composition containing a) 25 to 87 wt. % of KHSO.sub.5 containing triple salt b) 1 to 20 wt. % of at least one H.sub.2N(CH.sub.2).sub.nSO.sub.3H compound with n being 0, 1, 2 or 3, c) 1 to 8 wt. % of a surfactant d) 1 to 60 wt. % of a C.sub.2-C.sub.10 aliphatic dicarboxylic acid, optionally substituted with a hydroxyl and/or carboxylic group and e) 10 to 30 wt. % alkali metal phosphate.

A method for extending the use of water during the production of products for human consumption in food production facilities for an extended period of time of at least two production days and up to seven production days by delivering an initial chemical charge at the beginning of each production day to return the process water to the desired antimicrobial solution concentration to provide acceptable antimicrobial control of the process water over the extended period of time. The method providing acceptable antimicrobial control in the processing of any protein or non-protein based food products that require batch or continuous chilling as part of the production process. The length of time that the water may be used in a processing tank may be dramatically and safely increased before the processing tank is emptied for cleaning, sanitizing and refilling.
