  • Patent number: 11396457
    Abstract: A process of dissolving into to-be-treated water a peroxodisulfate and metal ions other than ions of alkali metals is performed by pouring equipment. An ultraviolet irradiation apparatus performs a process of treating the to-be-treated water, having the peroxodisulfate and the metal ions other than ions of alkali metals dissolved therein, with ultraviolet rays. By performing UV treatment on the to-be-treated water having the peroxodisulfate and metal ions dissolved therein, the inventive method and system achieve improved TOC decomposing performance and thus can particularly decompose a urea component in an efficient manner. Further, the to-be-treated water may be treated with an ion-exchange resin at a subsequent stage in such a manner that organic acids contained in the to-be-treated water having been subjected to the UV treatment are adsorbed to the ion exchange-resin, with the advantageous result that the concentration of TOC present in the to-be-treated water can be reduced.

  • Patent number: 11389806
    Abstract: Provided is a centrifugal field-flow fractionation device in which a liquid sample is less likely to leak from a channel and attachment and detachment work of a channel member is facilitated. By integrally forming an outer peripheral surface 162 and an inner peripheral surface 163 of a channel member 16, the channel member 16 is configured as one hollow member having a channel 161 formed inside. Thus, pressure resistance performance of the channel member 16 is improved, formation of a gap in the channel 161 can be prevented, and deterioration in sealing performance due to secular change is not generated. Accordingly, a liquid sample is less likely to leak from the channel 161. Further, since the channel member 16 can be handled as one member, attachment and detachment work of the channel member 16 is facilitated.

  • Patent number: 11384000
    Abstract: An adaptive electrokinetic dewatering system for dewatering slurry and soil deposits, including tailings deposits and a control system therefor. The control system automatically determines an optimal applied power specification, including sets of power parameters to be applied to the deposit being dewatered and when to apply each set of power parameters during the electrokinetic dewatering process. Furthermore, the control system automatically adjusts the applied power specification throughout the course of the dewatering process to account for the changing properties of the deposit. The control system determines the applied power specifications and adjustments to be made to them by simulating the electrokinetic dewatering process using a simulator which incorporates the latest measurements of the electrical, physical and chemical properties of the deposit being dewatered.

  • Patent number: 11344828
    Abstract: A drilling mud remediation and drilling cutting treatment device and method. There are three main components: a vacuum liquid solid separator; a pelletizer; and an induction furnace. The liquid solid separator has a seamless filter belt configured to carry a mixture of liquids and solids over a vacuum. A slurry comprised of drilling mud and cuttings is deposited on the filter belt. An applicator ensures that the slurry is deposited evenly across the entire filter belt at a uniform thickness. The vacuum removes most of the liquids for further treatment and reuse. The solids are transferred to a pelletizer which compacts them into relatively uniform pellets while removing much residual liquid. The pelletized cuttings are then passed through an induction furnace, which removes any residual liquids, renderings the cuttings safe for disposal.

  • Patent number: 11345616
    Abstract: A heterojunction composite material consisting of one-dimensional In2O3 hollow nanotube and two-dimensional ZnFe2O4 nanosheets and its application are disclosed. When using this material for catalytic reactions, the hollow cavity and two-dimensional nanosheets of hollow nanomaterials can not only reduce the migration distance to accelerate the electron-hole separation, but also provide a large surface area and rich active sites to promote pollution adsorption and surface catalysis. At the same time, multiple light scattering or reflection in the hollow cavity of the hollow nanomaterials can increase light absorption and utilization. In addition, the heterojunction photocatalyst constructed by growing two-dimensional semiconductor nanosheets on a tubular substrate can promote the effective separation of photogenerated electrons and photogenerated holes, thereby improving the catalytic efficiency.
