  • Method, equipment and specific drawer for membrane separation utilizing concentration polarization
    Patent number: 8506812
    Abstract: The present invention relates to a membrane separation method and a relevant equipment, in particular to a method and an equipment for membrane separation utilizing concentration polarization during membrane filtration process, especially, to a concentration process and equipment and a drawer special for drawing a concentration polarization layer. The direct removal of the concentration polarization layer from membrane surface not only decreases the adverse influence of concentration polarization on membrane separation but also obtains concentrated retention components, thereby significantly improving the ability to maintain membrane flux, solving the twinborn problems concerning concentration polarization and membrane fouling during the membrane separation process, and achieving a high-efficiency concentration for retention components.
    Type: Grant

    Date of Patent: August 13, 2013
    Assignee: Institute of Process Engineering, Chinese Academy of Sciences
    Inventors: Yinhua Wan, Xiangrong Chen, Zhiguo Su, Guanghui Ma, Xiaoguang Jiao, Fei Shen, Zhanfeng Cui
