A method for removing recalcitrant organic compounds from water includes exposing water to an oxidizing agent, thereby reducing an amount of at least some classes of dissolved organic matter in the water and adsorbing at least some of the remaining dissolved organic matter in the water onto a porous adsorbent, resulting in adsorbed organic matter on the porous adsorbent. The method includes thermally treating the adsorbed organic matter on the porous adsorbent to remove and degrade the adsorbed organic matter.

The invention corresponds to a composition for the treatment of polluted water and the method for the corresponding water treatment, wherein the composition comprises a flocculant, a stabilizer, an algaecide and further comprising chelator, disinfectant and oxygenator, wherein after diluting the composition in polluted water under certain stirring conditions, a water with properties of total hardness, total chlorine, total bromine, free chlorine, pH, alkalinity and cyanuric acid of a potable water is obtained.

Decontamination of water using low-cost technology for municipal wastewater treatment for safe irrigation reuse is provided. More specifically, wastewater is decontaminated by coagulation/flocculation followed by biological filtration while incorporating, in several stages, wastes from other industries such as ceramic kiln dust and biochar. Ceramic kiln dust and alum are used in a coagulation/flocculation process which is then followed by biofiltration using a biochar material.

A method and composition are provided for breaking down a contaminant. A method for breaking down a contaminant in animal drinking water or an organic chemical agent includes providing a plurality of sporulated microbes. A composition for breaking down a contaminant in animal drinking water or an organic chemical agent includes a plurality of sporulated microbes.

A method for producing a nanocomposite sorbent comprising carbon nanotube-grafted acrylic acid/acrylamide copolymer which involves copolymerization of acrylic acid and acrylamide in the presence of an aqueous dispersion of carbon nanotubes. The method yields a nanocomposite sorbent material having a reversible adsorption capacity phenol of 5 to 2500 μg of phenol per mg of nanocomposite sorbent. Also disclosed is a method for removing organic pollutants from water using the nanocomposite sorbent.

Disclosed is an electro-Fenton-like (EFL) platform wherein an electrochemically produced acidic environment supports heterogeneous Fenton-like reaction for high throughput water treatment. The platform enables treatment of contaminated 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 (TDS), 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.

The present disclosure relates to devices, systems, and methods for using foam fractionation to remove non-polar waste molecules, including, but not limited to, sewage bacteria, environmental contaminants, and/or sediment/turbidity caused by dredging activities, from open-water aquatic environments. Some foam fractionation systems disclosed herein generally include a plurality of partially submerged foam fractionation devices, each foam fractionation device including a foam collection reservoir positioned above a waterline and a reaction chamber positioned at least partially below the waterline. In some embodiments, the partially submerged foam fractionation device is supported by a base structure, such as a barge, boat, skiff, or the like. In other embodiments, the partially submerged foam fractionation device is a free-floating device.

Disclosed are methods, apparatuses and systems for the remediation of contaminated soils, groundwater, water, and/or waste using a combination of reagents. The disclosed methods may be used to treat various recalcitrant halogenated substances, such as perfluoroalkyls and polyfluoroalkyls. Particular combinations of reagents that may be used in the disclosed methods include but are not limited to: (1) persulfate, oxygen and ozone; (2) persulfate, salt, oxygen and ozone; (3) persulfate, phosphate, and/or oxygen; (4) persulfate, phosphate, oxygen and ozone; (5) persulfate, phosphate, salt and oxygen (6) persulfate, phosphate, salt, oxygen and ozone; (7) oxygen and salt; and (8) air and salt. The disclosed methods may enhance destruction of organic contaminants in the liquid phase and may also control the rate of aerosol or foam formation relative to the rate of chemical oxidation and/or reduction/transfer.

In an embodiment, a circuit includes: a transformer defining an inductive footprint within a first layer; a grounded shield bounded by the inductive footprint within a second layer separate from the first layer; and a circuit component bounded by the inductive footprint within a third layer separate from the second layer, wherein: the circuit component is coupled with the transformer through the second layer, and the third layer is separated from the first layer by the second layer.
