Abstract Hybrid wastewater treatment systems offer viable solutions to enhance the removal of complicated contaminants from aqueous system. This innovation has opened new avenues for advanced processes. Herein, a novel TiO 2 –ZnO functionalized coal fly ash-based ceramic membrane was fabricated by utilizing combined pressing and sintering method. The intrinsic properties membranes were characterized their chemical physical such as stability, mechanical water absorption, porosity established. shape, crystallinity, thermal characteristics, functional groups present also determined using SEM, XRD, TGA, FTIR studies, respectively. results showed that with 0.5 g sintered at 850 °C exhibited best thermal, possessed required ultrafiltration applications. Photocatalytic degradation tetracycline (TC) model pollutant examined optimum efficiency 77% achieved within 100 min visible irradiation membrane. Moreso, found be stable 73% after 5 consecutive cycles reusability study, showing negligible loss efficiency. scale-up photocatalytic utilization in real industrial applications will confirm robustness.
