Abstract:
The present invention is generally directed to a versatile fluid treatment system which includes: a mobile device; a track system connected to the mobile device; one or more treatment vessels removably attached to the track system, each treatment vessel comprising a treatment material disposed inside the treatment vessel, at least one fluid inlet, and at least one fluid outlet; an input conduit that receives a fluid to be treated, the input conduit in fluid communication with the fluid inlet on the treatment vessel; and an output conduit in fluid communication with the fluid outlet on the treatment vessel, the output conduit receives treated fluid from the treatment vessels via the fluid outlet.
Abstract:
In one embodiment, the invention is to an ion exchange resin composition comprising a metal-functionalized exchange resin comprising from 3% to 94% metal-functionalized active sites; and a non-metal-functionalized exchange resin comprising non-metal-functionalized active sites.
Abstract:
Chalcogenide compounds, including ternary and quaternary tin and antimony chalcogenides, for use as absorbents in the remediation of hazardous materials are provided. Also provided are methods for using the chalcogenides in the remediation of ionic and elemental metals from aqueous and non-aqueous fluids.
Abstract:
A filter assembly for the filtration of a liquid or gaseous substance comprising a frame and a plurality of filter members fitted in the frame in parallel relation to one another. Each filter member consists of two elements connected together to form a hollow interior, the substance to be filtered being introduced at one side of the filter and passing through the hollow interior and then through the filter elements for discharge between adjacent filter elements of adjoining filter memers. Each filter element comprises a layer of fiber glass and at least one fleece layer, the two layers being connected by needle felting together at locations between the connections of the filter elements constituting the filter member.
Abstract:
Methods and systems for an integrated acid regeneration of ion exchange resins are disclosed for use in cleaning applications. Acid resins designed for use in a variety of cleaning application using a treated, softened, acidic water source are disclosed. Various methods of using the softened acidic water generated by acid regenerate-able ion exchange resins within a cleaning application, e.g. ware wash machine, are disclosed to beneficially reduce spotting, filming and scale buildup on treated surfaces, reduce and/or eliminate the need for polymers, threshold reagents and/or rinse aids, and using protons generated in the acidic water effluent for triggering events useful in various cleaning applications.

Abstract:
A process for the regeneration of an acid gas absorbent comprising an amine and heat stable salts by phase separation, comprising a) mixing the acid gas absorbent with an alkaline solution, to form a mixture with a pH above the pH equivalence point of the amine; b) cooling the mixture to a temperature below 500C; c) separating the mixture into a regenerated acid gas absorbent and a waste stream; d) collecting the regenerated acid gas absorbent separate from the waste stream.
Abstract:
An activated carbon filter with reduced leachable arsenic comprising activated carbon, a binder material for binding activated carbon into a filtration mesh and an arsenic adsorbent in a concentration of less than about 5% for reducing leachable arsenic inherent in the activated carbon.
