  • Patent number: 11149135
    Abstract: A system for remediation of perfluoroalkyl substances (PFASs) has a multiplicity of ?-cyclodextrins (?-CDs) and/or modified ?-CDs combined with a vehicle additive, and a delivery device. Modified ?-CDs can contain a single amine functionality at a single primary carbon or single secondary carbon of the ?-CD. The vehicle additive can be powdered activated carbon (PAC). The delivery device is a column, a pouch, a packet, or a sheet that can permit the contacting of a fluid environment with the ?-CDs and vehicle additive. The system of remediation can be used for a fluid environment or for biological organisms. CD-based fluorescent sensors can detect PFASs in the environment.

  • Patent number: 11124859
    Abstract: The invention relates to a lithium adsorption-desorption apparatus including a plurality of reaction tanks arranged in a row; a guide rail disposed at an upper portion of the reaction tank; a movable driving unit coupled to a moving means that moves along the guide rail; and a reaction housing which is mounted to the driving unit, and can be vertically moved or rotated in a state in which the lithium adsorbent is fixed thereto, and after immersing in the reaction tank, accelerates adsorption or desorption of lithium, and after being lifted, discharges residual solution from the lithium adsorbent by rotation movement. Therefore, the lithium adsorption desorption apparatus can fix a large amount of lithium adsorbent and immerse it in a lithium-containing solution to effectively adsorb lithium and then quickly desorb lithium in a desorption solution, and can efficiently wash the lithium adsorbent in a cleaning solution.

  • Patent number: 11033893
    Abstract: A continuous resin regeneration system includes a process by which resin in need of being recharged is continuously recharged and cleaned with a plurality of two-set filtration columns so that resin regeneration and the flow of influent is continuous and interrupted. Downstream filtration columns also undergo this cycling but at slower and related rates as the first column with the dirtiest water will naturally degrade resin faster than the downstream columns. Contaminated influent is cleaned by the continuously recharged resin in multiple column sets. The degree of cleaning of earlier filtration columns affects the resin flow rate of later filtration columns.
