  • Patent number: 10479701
    Abstract: Systems and methods related to desalination systems are described herein. According to some embodiments, the desalination systems are transiently operated and/or configured to facilitate transient operation. In some embodiments, a liquid stream comprising water and at least one dissolved salt is circulated through a fluidic circuit comprising a desalination system. In some embodiments, a portion of the desalination system (e.g., a humidifier) is configured to remove at least a portion of the water from the liquid stream to produce a concentrated brine stream enriched in the dissolved salt. In certain cases, the concentrated brine stream is recirculated through the fluidic circuit until the concentrated brine stream reaches a relatively high density (e.g., at least about 10 pounds per gallon) and/or a relatively high salinity (e.g., a total dissolved salt concentration of at least about 25 wt %).

    Abstract: A copolymer and water/ethanol solvent solution capable of binding with airborne contaminants or potential airborne contaminants, such as biological weapon agents or toxic particulates, coagulating as the solvent evaporates, and adhering the contaminants to a surface so as to inhibit the re-suspension of such contaminants. The solution uses a water or ethanol/water mixture for the solvent, and a copolymer having one of several functional group sets so as to have physical and chemical characteristics of high adhesion, low viscosity, low surface tension, negative electrostatic charge, substantially neutral pH, and a low pKa. Use of the copolymer solution prevents re-aerosolization and transport of unwanted, reactive species thus increasing health and safety for personnel charged with decontamination of contaminated buildings and areas.

  • Patent number: 7390432
    Abstract: An enhanced formulation and method of making that neutralizes the adverse health effects of both chemical and biological compounds, especially chemical warfare (CW) and biological warfare (BW) agents, and toxic industrial chemicals. The enhanced formulation according to the present invention is non-toxic and non-corrosive and can be delivered by a variety of means and in different phases. The formulation provides solubilizing compounds that serve to effectively render the chemical and biological compounds, particularly CW and BW compounds, susceptible to attack, and at least one reactive compound that serves to attack (and detoxify or kill) the compound. The formulation includes at least one solubilizing agent, a reactive compound, a bleaching activator and water.

  • Patent number: 7335808
    Abstract: Compositions and methods for destroying biological agents such as toxins and bacteria are provided wherein the substance to be destroyed is contacted with finely divided metal oxide or hydroxide nanocrystals. In various embodiments, the metal oxide or metal hydroxide nanocrystals have reactive atoms stabilized on their surfaces, species adsorbed on their surfaces, or are coated with a second metal oxide. The desired metal oxide or metal hydroxide nanocrystals can be pressed into pellets for use when a powder is not feasible. Preferred metal oxides for the methods include MgO, SrO, BaO, CaO, TiO2, ZrO2, FeO, V2O3, V2O5, Mn2O3, Fe2O3, NiO, CuO, Al2O3, SiO2, ZnO, Ag2O, [Ce(NO3)3—Cu(NO3)2]TiO2, Mg(OH)2, Ca(OH)2, Al(OH)3, Sr(OH)2, Ba(OH)2, Fe(OH)3, Cu(OH)3, Ni(OH)2, Co(OH)2, Zn(OH)2, AgOH, and mixtures thereof.

  • Patent number: 7282470
    Abstract: A decontamination formulation and method of making that neutralizes the adverse health effects of both chemical and biological compounds, especially chemical warfare (CW) and biological warfare (BW) agents, and toxic industrial chemicals. The formulation provides solubilizing compounds that serve to effectively render the chemical and biological compounds, particularly CW and BW compounds, susceptible to attack, and at least one reactive compound that serves to attack (and detoxify or kill) the compound. The formulation includes at least one solubilizing agent, a reactive compound, a bleaching activator, a sorbent additive, and water. The highly adsorbent, water-soluble sorbent additive (e.g., sorbitol or mannitol) is used to “dry out” one or more liquid ingredients, such as the liquid bleaching activator (e.g., propylene glycol diacetate or glycerol diacetate) and convert the activator into a dry, free-flowing powder that has an extended shelf life, and is more convenient to handle and mix in the field.

  • Patent number: 7186877
    Abstract: Methods and systems for processing vesicants as well as other irritants are described. In some methods a vesicant, for example, a Lewisite such as the L1 form, the L2 form, L3 form, or combination thereof, is combined with permanganate, for example, as an aqueous solution of sodium permanganate. The methods can include releasing the vesicants or irritants from a munition, for example, by explosively rupturing the munition.

  • Patent number: 7087805
    Abstract: A method and apparatus for neutralizing biological and/or chemical warfare agents using an ozone-containing solution. The ozone-containing solution is produced by combining ozone-containing gas with an ozone vehicle, such as an organic solution. The ozone-vehicle prolongs the shelf life of the ozone to allow for extended periods of storage. A storage container is used to store the ozone-containing solution and facilitate its transportation to an environment contaminated by the biological and/or chemical warfare agents, or near a potential site for biological or chemical attack. The ozone-containing solution is drawn out of the storage container to apply it to a contaminated environment.

  • Patent number: H2198
    Abstract: A method of decontaminating solids contaminated with chlorinated hydrocarbons includes a first step of heating the contaminated solids at a temperature high enough to volatize chlorine contaminates but below a temperature range favorable to the formation of the dioxins and furans to dechlorinate the contaminated solids. Volatilized chlorine contaminates are removed from the dechlorinated contaminated solids. The dechlorinated contaminated solids are then purged with an inert gas to remove oxygen from the dechlorinated contaminated solids. Thereafter the dechlorinated contaminated solids are heated in the absence of oxygen to a temperature sufficient to crack hydrocarbons contaminating the solids to lower molecular weight hydrocarbons.
