  • Patent number: 10732098
    Abstract: Processes, compositions, and sensors for sensing a variety of toxic chemicals based on colorimetric changes. Exemplary process for sensing a toxic chemical includes contacting a toxic chemical, or byproduct thereof, with a sorbent that includes a porous metal hydroxide or a porous mixed-metal oxide/hydroxide and a transition metal reactant suitable to react with a toxic chemical or byproduct thereof. The sorbent is contacted with the toxic chemical or byproduct thereof for a sampling time. A difference between a post-exposure colorimetric state of the sorbent and a pre-exposure colorimetric state of the sorbent is determined to thereby detect exposure to, or the presence of, the toxic chemical or byproduct thereof.

According to one embodiment the waste byproduct is gypsum. The gypsum can be obtained from a flue gas desulfurization process. According to another embodiment the waste byproduct is a calcium carbonate containing byproduct which is reacted with acid tar to produce calcium sulfide. The calcium carbonate containing byproduct can come from a Solvay process.

  • Patent number: 8263819
    Abstract: The invention resides in a method for manufacturing a metallic hydroxide-based and metallic oxide-based powder, which is self-dispersing in water, characterized in that a metallic oxide powder is partially treated with a polymer in the form of an aqueous emulsion and/or solution, in such a way that the level of metallic hydroxide by dry weight within said treated powder is less than 99% of its total weight, and in that said polymer is a water-soluble homopolymer or copolymer containing at least one vinylic monomer. In one particular variant, the polymer is a water-soluble copolymer containing a vinylic monomer and a non-ionic monomer, and the metal is calcium and/or magnesium. The invention also pertains to the powders obtained, their uses in aqueous suspensions, in treating waste, as a chemical additive, or as a soil amendment.

  • Publication number: 20120220810
    Abstract: This invention provides an optimal method for stabilization of heavy metal bearing paint residue subject to acid and water leaching tests or leach conditions by addition of environmental safe, worker safe, and multi-media compatible stabilizing agents to the blast media, thus allowing for paint residue stabilization outside of or within an OSHA containment building or collection device, such that leaching of heavy metals such as lead are inhibited to desired levels. The resultant stabilized paint residue and spent blast media mixture is suitable for on-site reuse, off-site reuse, or disposal as RCRA non-hazardous waste.

  • Publication number: 20120219519
    Abstract: The invention relates to the use of a by-product from drinking water treatment, namely alum sludge, in a method and composition for the stabilisation of contaminants (e.g. arsenic and polycyclic aromatic hydrocarbon) in materials such as soils and other solid or semi-solid matrix types. The composition may also comprise a reactive carbon material such as activated carbon. Further, the composition may comprise a solidifier such as calcium silicate-based cement to enable the stabilisation and immobilisation of contaminants.

  • Publication number: 20120215048
    Abstract: This invention provides a method for heavy metal solubility reduction in waste and material by maximization of water hydration, minimization of surface area and mass, maximization of atmospheric carbonation, optimization of pH environment and optimization of stabilizing agents, such that leaching of heavy metals is inhibited to desired levels. The resultant waste or material after sequenced optimized solubility reduction would be suitable for disposal as RCRA non-hazardous waste or reuse in the environment.

  • Patent number: 8148594
    Abstract: A process and system for treating waste water containing contaminants to prevent excessive accumulation on demineralizer media of a driver contaminate capable of such accumulation before another contaminant can reach a predetermined level of accumulation. The waste water is treated upstream of the demineralizer media with removal means for specifically removing the driver contaminant while leaving the other contaminant for subsequent removal by the demineralizer media. The amount of accumulation on the demineralizer media of the other contaminant is monitored, and the supplying of treated waste water to the demineralizer media is terminated when its accumulation reaches the predetermined level.

  • Patent number: 8043399
    Abstract: A method for detoxifying spent CCA (copper, chromium, arsenic) treated wood, from which CCA is efficiently removed from the wood, allowing both the CCA and the wood to be reused has been developed. The method comprises the steps of (1) microwave-enhanced acid extraction of CCA, (2) separation of the acid-containing CCA solution from the wood, (3) separation/precipitation of CCA from the acid extract, (4) recovery and regeneration of CCA-bearing precipitant for reuse in the wood preservation industry, (5) recycling recovered acid solution, (6) microwave-assisted liquefaction of the extracted wood, and (7) use of detoxified liquefied wood to form polymeric materials such as polyurethanes and phenolic resin adhesives. The recovered CCA may be used to treat wood. The recovered acids may be used to extract CCA from CCA-treated wood, and the liquefied wood may be used as phenolic or polyurethane resins.
