    Abstract: Systems and methods are described that facilitate generating and storing a concentrated copper and silver ion solution for treating a remote water volume (e.g., a pool, fountain, hot tub, cooling tower, etc.), in accordance with various features described herein. Citric acid and a water-soluble binding polymer are added to a volume of water. The intermediate solution is circulated past an ion generator for a predetermined time period, and copper ions generated thereby are bound by the binding polymer and/or chelated by the citric acid. Once a desired concentration of copper ions has been achieved, the concentrated solution is stored in portable vessels for transport to the remote water volume. Concentrated solution is added to the remote water volume to achieve a concentration therein of approximately 0.2-0.3 ppm.

  • Patent number: 8815096
    Abstract: An integrated process for removing sulfate from water sources, such as pretreated acid mine drainage (AMD). The multivalent cation (MVC) content of a sulfate stream is reduced by strong acid cation (SAC) ion exchange and sulfate is concentrated with a membrane system and separated as precipitate and overflow. Precipitation results from reaction of sulfate with MVC produced by regeneration of SAC with sodium chloride. The overflow is reacted with carbonate to precipitate MVC, generate sodium chloride and give a further overflow stream. This latter stream is concentrated to a level capable of being a regenerant for the SAC and when needed, used to regenerate the SAC and produce MVC for sulfate precipitation. The process minimizes the use of chemicals by treating, reconcentrating and recycling input species. Capital expenditures are minimized by precipitation of only side streams.

  • Patent number: 8809606
    Abstract: Methods and apparatus for processing of waste and low-value products to produce useful materials in reliable purities and compositions, at acceptable cost, without producing malodorous emissions, and with high energy efficiency are disclosed. In particular, multi-stage processes are disclosed to convert various feedstocks such as offal, animal manures, municipal sewage sludge, tires, and plastics, that otherwise have little commercial value, to useful materials including gas, oil, specialty chemicals, and carbon solids. Disclosed processes subject the feedstock to heat and pressure, separates out various components, then further applies heat and pressure to one or more of those components. Various materials produced at different points in the process may be recycled and used to play other roles within the process. Also disclosed are apparatus for performing multi-stage processes of converting waste products into useful materials, and at least one oil product that arises from the process.

  • Patent number: 8795509
    Abstract: A process for preparing a pure ammonium perrhenate includes producing a first aqueous suspension containing an ammonium perrhenate. A stoichiometric amount of a nitric acid is added to the first aqueous suspension so as to produce a second suspension. The second suspension is introduced into a cathode space of an electrolysis cell. The electrolysis cell is divided by a cation-exchange membrane into the cathode space and an anode space. The nitric acid is cathodically reduced to a nitrous acid in the cathode space by applying an electric potential. The nitrous acid is reacted with ammonium ions of the ammonium perrhenate so as to form an aqueous perrhenic acid. Potassium ions are removed from the aqueous perrhenic acid. At least a stoichiometric amount of ammonia is added to the aqueous perrhenic acid so as to produce the pure ammonium perrhenate.
