A system and method for treatment of a wastewater fluid is described. The system includes a gas supply system to provide a process gas into the wastewater fluid, a pulsed electrical-power generator to generate high electrical voltage pulses and a reactor apparatus pneumatically coupled to the gas supply system, and electrically coupled to the pulsed electrical-power generator. The reactor apparatus is configured to produce a plurality of gas microbubbles of the process gas injected into the wastewater fluid supplied into the reactor apparatus for the treatment, and to apply the high electrical voltage pulses generated by the pulsed electrical-power generator to said plurality of the microbubbles. The high electrical voltage pulses have energy sufficient to create a plasma glow discharge within the plurality of the microbubbles, and in an interface of the microbubbles with the wastewater fluid.

Systems and methods for providing a deionization chamber having a plurality of electrodes corresponding to a plurality of register levels thereby forming a gradient of electrical amplitudes and frequencies within the deionization chamber.

A metal organic framework includes metal-containing secondary building units and perfluorinated linkers (e.g., pefluorinated arene linkers, perfluorinated heteroarene linkers, etc.). The metal may be copper, zinc, hafnium, zirconium, aluminum, gallium, or indium. A method for removing contaminants from wastewater may utilize the metal organic framework. The contaminants may include arenes.

A process for producing a polyaluminum chlorosulfate (PACS) includes providing solid aluminum hydroxychloride, providing aluminum sulfate, mixing the solid aluminum hydroxychloride with the aluminum sulfate, in the presence of water, to form an aqueous milky suspension, wherein, on a dry weight basis, the ratio of the aluminum hydroxychloride to the aluminum sulfate is 0.75-20 parts aluminum hydroxychloride to 1 part aluminum sulfate, and maintaining the milky suspension for a period sufficient to allow the milky suspension to form a clear to slightly turbid solution including the PACS, the PACS having a basicity of 55 to 75%, the average molecular weight of the PACS is greater than or equal to 95 and less than or equal to 111, and salts present in the PACS comprise 0-1.0% sodium chloride by weight and 0-1.0% sodium sulfate by weight.

Systems for water treatment include a preprocessing stage, an ultraviolet treatment stage, and a filtering stage. The preprocessing stage includes first and second chambers including first and second filter media. The first and second chambers include perforated plates. The first chamber and second chamber are vertically arranged in a filter tower. The ultraviolet treatment stage receives water in a plurality of reactor tanks. Each reactor tank of the plurality includes an inlet, an outlet, crystal sleeve disposed centrally to the interior of the reactor tank, and a UVC light source contained within the crystal sleeve. A controller operates the ultraviolet treatment stage to sequentially fill each reactor tank and sequentially drain each reactor tank and operates a respective UVC light source to emit UVC wavelength radiation within a respective reactor tank while water is in the respective reactor tank.

A reaction product of silicious material, aluminum metal, and an aqueous solution is disclosed. The reaction product may be used to form a sorbent that is used to purify water of contaminants such as biological matter, dyes, soluble metals, arsenic, or radioactive elements. Additives may be added to the reaction product to further improve the sorption qualities of the sorbent. Water purification devices having the sorbent are also disclosed.
