  • Patent number: 11952292
    Abstract: A method of processing off gas from a chemical plant, where the off gas includes carbon dioxide and water. The processing of the off gas involves separating the off gas into a gas phase and a liquid phase and using one or more ion-exchange resin bed(s) and one or more granular activated carbon bed(s) to separate unwanted organic materials from the liquid phase. Based on this separation, water can be recovered that has less than 10 wt. % of the unwanted organic compounds originally in the liquid phase of the off gas.

  • Patent number: 11834638
    Abstract: A conductive aqueous solution production device 1 has an ion exchange device 2 mounted on the way of the main pipe 11 supplying ultrapure water W as raw water, a supply pipe 12 which joins the main pipe 11 on the downstream side of the ion exchange device 2, and a conductivity-imparting substance supply device 3. For example, if the conductivity-imparting substance is ammonia, since the ions are cations, that is, ammonium ions (NH4+), it is preferable that an ion exchanger which fills the ion exchange device 2 be a cation exchange resin. If the conductivity-imparting substance is carbon dioxide, the ions are anions, that is, bicarbonate ions (HCO3?) or carbonate ions (CO32?), and therefore it is preferable that the ion exchange device 2 be filled with an anion exchange resin. Such a conductive aqueous solution production device is capable of producing a conductive aqueous solution with a stable concentration, and achieves excellent follow-up performance with respect to a change in concentration.

    Abstract: A process to remove transition metals from waste water. The process includes the steps of passing waste water to a first pH resin bed, monitoring the effluent from the first resin bed, and adjusting pH to greater than 4. The effluent is passed to a first stage liquid tank and to a first brackish water membrane to filter out complex metals. Rejected effluent from the first brackish water membrane is passed to a second stage liquid tank and thereafter to a second brackish water membrane. The permeate from the second brackish water membrane is passed back to the first stage liquid tank. The rejected effluent from the second brackish water membrane is heated and evaporated. The evaporated effluent is condensed so that metal crystals are gathered for disposal. The permeate through the first brackish membrane is passed to an EDTA resin bed to sequester metal ions. The pH of the discharge from the second pH resin bed is adjusted to between 7 and 11.

In additional embodiments, the solids that have been disinfected by radiation are mixed with a suitable inert filler material to produce a soil substitute, fertilizer, compost, or other soil additive. The liquid phase is treated in a substantially smaller system than would be required for treating the full-strength wastewater that can include a suspended media biological regeneration reactor system.

  • Patent number: 8784661
    Abstract: Techniques, systems, apparatus, and materials are disclosed for generating multi-purpose liquid fuel for isolating contaminants and storing energy. In one aspect, a method of producing a liquid fuel includes forming a gaseous fuel (e.g., by dissociating biomass waste using waste heat recovered from an external heat source). Carbon dioxide emitted from an industrial process can be harvested and reacted with the gaseous fuel to generate the liquid fuel. A hazardous contaminant can be dissolved in the liquid fuel, with the liquid fuel operating as a solvent or continuous phase for a solution or colloid that isolates the hazardous contaminant from the environment. The hazardous contaminant can include at least one of a carbon donor and a hydrogen donor.

  • Publication number: 20140137615
    Abstract: Hydrophobic contaminants are removed from sludge that has been liquidized by violent shearing, by stirring a hydrophobic sorbent substance material into the sludge. After a period of time in which the contaminants are sorbed into the sorbent, the sorbent substance is separated from the sludge by gravity-settling, centrifuging, etc, where the sorbent is a liquid, or by filtration etc where the sorbent is a solid. Some sorbents have a melting point such that the sorbent can be liquid for good dispersal in heated sludge, and then can be solid when the sludge has cooled, whereby the sorbent can be removed e.g by filtration. Liquefaction by violent shearing causes the biosolids in the sludge to go into solution, which leaves the hydrophobic contaminants more available to be sorbed.

  • Patent number: 8728319
    Abstract: A purifying device and a process for deeply treating printing and dyeing wastewater are provided. The device includes a nanometer catalytic microelectrolysis system, a membrane filtration and separation system and a a membrane washing regeneration system. The method includes the following steps of: drawing the printing and dyeing wastewater by a first water pump (12), pumping a first part of the wastewater into a nanometer catalytic microelectrolysis tank (13) to perform catalysis microelectrolysis, and a second part of the wastewater into a neutralization tank (16) to mix with the water from the nanometer catalytic microelectrolysis tank (13) to precipitate, filtering the wastewater by a sand filtration tank (17), and then pumping the wastewater into an adsorption and filteration device of granular active carbon (18) for adsorption and filtration. The process has lower cost and higher energy efficiency, and can realize recycled water to be reused.

  • Patent number: 8709259
    Abstract: The present invention is a wastewater treatment method using dried BOF slag and hydrogen peroxide, wherein hydrogen peroxide is oxidized to generate hydroxyl radicals that reacts with soluble metal contaminants in the sludge such that these contaminants can be adsorb on the catalyst particles and/or eliminated from the wastewater stream by separation techniques. The process can use catalytic oxidation for soluble metals removal. In addition, catalytic oxidation can produce a filtered water saturated with Oxygen and higher in pH resulting in enhanced precipitation of soluble metals when softening agents, such as Sodium Carbonate, are added in a subsequent processing step. Another embodiment of the present invention is a method using ferrous sulfate for removing soluble metals in wastewater, followed by Catalytic Oxidation to remove soluble Fe without addition of metal salts, and removing sulfates by adding Barium Carbonate.

  • Publication number: 20140102986
    Abstract: A method and treatment unit for removing particulate mercury from aqueous streams such as wastewater streams from hydrocarbon processing is disclosed. Mercury solids are removed by means of a surface filter configured in the shape of a bag. The separated solid mercury can be thickened and dewatered by removing the spent filter bag from service and allowing the water to drain and/or evaporate. The dewatered solids can then be disposed of together with the spent bag to an approved solid waste disposal facility. Coagulants, flocculants, and mercury precipitants can be injected upstream of the filter bag if required to increase removal efficiency by precipitating dissolved ionic mercury and increasing the particle size of the mercury solids. Following bag filtration, activated carbon or an alternative technology (e.g.
