Abstract: The present disclosure relates to a membrane filter for water and wastewater treatment including a membrane filter, hydrophilic polymers formed on the membrane filter; and quorum quenching microorganisms cross-linked with the membrane filter by the hydrophilic polymer. The quorum quenching microorganisms are attached to the surface of the membrane filter for water and wastewater treatment, resulting in a higher initial permeation pressure than a conventional membrane, but the quorum quenching microorganisms may effectively prevent the phenomenon of quorum sensing, allowing the formation of a biofilm, thereby improving the life of the membrane filter for water and wastewater treatment.

Abstract: The present invention relates to an electrochemical advanced oxidation process combined with a membrane in which electrode reactions and membrane filtration occur simultaneously, a water treatment device based on the electrochemical advanced oxidation process, and a water treatment system using the water treatment device. The electrochemical advanced oxidation process includes: providing a membrane electro-oxidation tank where electrodes are combined with a membrane; accommodating wastewater containing pollutants in the membrane electro-oxidation tank; and supplying power to the electrodes to decompose the pollutants and simultaneously separating particles through the membrane (water treatment). The electrodes are arranged downstream of the membrane. Gases released from the electrodes induce a vertical flow of the fluid to improve the contact efficiency between a reactive solution and the electrodes and remove the pollutants attached to the surface of the membrane. According to the present invention, a mechanism of decomposing pollutants using the electrodes and a mechanism of separating particles through the membrane take place simultaneously, enabling effective removal of the pollutants. The electrodes are arranged downstream of the membrane. With this arrangement, gases are produced from the electrodes to improve the electrolysis reactivity and the filtration efficiency of the membrane.
