  • Patent number: 10875792
    Abstract: The present disclosure relates to a capacitive deionization (CDI) system for desalinating salt water. The system may have a capacitor formed by spaced apart first and second electrodes, which enable a fluid flow containing salt water to pass either between them or through them. An input electrical power source is configured to generate an electrical forcing signal between the two electrodes. The electrical forcing signal represents a periodic signal including at least one of voltage or current, and which can be represented as a Fourier series. One component of the Fourier series is a constant, and a second component of the Fourier series is a sinusoidal wave of non-zero frequency which has the highest amplitude of the additive components of the Fourier series. The amplitude of the sinusoidal wave component is between 0.85 and 1.25 times the amplitude of the periodic signal.

  • Publication number: 20130180861
    Abstract: A Ti02-based photocatalyst is fabricated as a composite of titania with adhered nanostructures which contain a non-noble metal in galvanic contact with a noble metal. The catalyst effectively overcome aging and/or deactivation effects observed in a system free of the non-noble metal. The composite material showed a corrosion protective effect on the photoactivity of fresh catalyst for over 180-240 days, and it enhanced the rate of the water reduction reaction relative to bare Ti02. Variations in porosity and non-noble metal content of the alloy portion of the nanostructures influenced the performance of the catalyst composite. The protective effect of the non-noble metal is through a cathodic corrosion protection mechanism.

  • Patent number: 8475645
    Abstract: A cooling water circulation apparatus is capable of limiting attachment of microorganisms and scale in an environmentally friendly manner. An electrolytic device 10 is provided on a cooling water circulation route R1. In the arrangement, mineral contents such as calcium ions and magnesium ions contained in cooling water W are deposited as scale S on an electrode 12A or 12B in an electrolytic step, thereby enabling the mineral contents to be removed from the cooling water W. Even if the hardness of the cooling water W is increased by evaporation of the water with elapse of time, the hardness can be reduced by the electrolytic processing. Thus, the deposition of the scale S in the circulation route R1 can be reduced. Further, the scale S deposited on the electrode 12A or 12B can be easily separated by operating while reversing the polarities of the electrodes 12A and 12B at predetermined time intervals.

  • Patent number: 8470056
    Abstract: The method for producing a non-aqueous electrolyte secondary battery of the invention includes: (a) a step of preparing an electrode mixture slurry, (b) an ionization step of oxidizing and ionizing a metal impurity present in the electrode mixture slurry, and (c) a step of producing an electrode by using the electrode mixture slurry after the ionization step. In the invention, when the electrode mixture is in the form of a slurry, the metal impurity contained in the electrode mixture is ionized to minimize the amount of the impurity. Therefore, the invention can provide a highly reliable non-aqueous electrolyte secondary battery while minimizing a decrease in production yield by the metal impurity.

  • Patent number: 8460520
    Abstract: Contaminants are removed from raw water or discharge water from plants, such as sewerage and industrial plants, by applying direct current through an array of spaced, alternately charged electrodes to eliminate or minimize clogging of the electrodes with precipitated contaminants. Polarity may be switched periodically to assist in eliminating or minimizing clogging. In illustrated embodiments, electrode arrays are contained in housings of dielectric material to form modules, To increase processing capacity, the modules are arranged in parallel arrays. Alternatively, a single module is scaled up for large or industrial applications or scaled down for personal use. Instead of housing the electrode arrays in modules through which liquid passes, the electrode arrays for some batch applications are dipped in the water or aqueous solutions.
