Hien Thi NGUYEN has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Aquifer storage and recovery system using natural coagulant
    Patent number: 11142472
    Abstract: The present invention is an aquifer storage and recovery system using a natural coagulant, in which in purifying raw water through aquifer storage and recovery, assimilable organic carbon (AOC) included in the raw water is effectively removed using a natural coagulant produced in the aquifer storage and recovery process, thereby reducing the time required to purify raw water by aquifer storage and recovery.
    Type: Grant
    Filed: November 8, 2019
    Date of Patent: October 12, 2021
    Assignee: KOREA INSTITUTE OF SCIENCE AND TECHNOLOGY
    Inventors: Seong Pil Jeong, Kyungjin Cho, Jae Woo Choi, Seok Won Hong, Seunghak Lee, Eun-Ju Kim, Jae Shik Chung, Hien Thi Nguyen, Youngjae Kim
