Fabrication of Cu 1.4 Mn 1.6 O 4 modified catalytic ozonation ceramic membrane for membrane fouling elimination and micro‐pollutant degradation

Abstract In this experiment, a novel catalytic ceramic membrane (CCM) with spherical Cu 1.4 Mn 1.6 O 4 material loading was prepared through hydrothermal in situ growth method. The synergistic effects of membrane separation and catalytic ozonation on membrane antipollution and degradation of micro‐pollutants were systematically investigated. The results indicated that the degradation efficiency of bisphenol A by CCMs reached 85.7% with a stable normalized flux of 0.90 under the operating conditions of [O 3 ] = 4 g/h, transmembrane pressure = 0.2 bar, and pH = 6. In addition, the results showed that the composite bimetallic oxides have good stability by measuring the leaching concentration of metal ions during the catalytic process. This study provides a promising strategy for in situ growth of catalytically active composite bimetallic oxides on the surfaces of ceramic membrane and for mitigation of membrane fouling complex water treatment.
