Fabrication of Cu1.4Mn1.6O4 modified catalytic ozonation ceramic membrane for membrane fouling elimination and micro-pollutant degradation

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.
