Treated effluent from an electrically enhanced membrane bioreactor (eMBR) was filtered through MnO2 or TiO2 nanoporous membranes for the removal of residual heavy metals, bacteria, and biological oxygen demand (BOD). The fresh and spent membranes were characterized via energy-dispersive X-ray spectroscopy (EDAX), zeta potential analysis, and thermogravimetric analysis (TGA). Water analysis was performed by means of UV/Vis spectrophotometry. For most contaminants, eMBR-TiO2 showed highest removal efficiency compared to MnO2 because of the combined adhesion and photocatalytic effects of TiO2. Meanwhile, eMBR-MnO2 provided higher removal efficiency for Fe.
