The anode chamber contains microbes, Membrane and bio-electrochemical system activated carbon (AC)/graphite granules and Al anode. It was separated from the cathode chamber containing Wastewater treatment bifunctional catalytic and ﬁltration membrane cathode (loaded with Fe/Mn/C/F/O catalyst) by a multi-medium chamber (MMC) ﬁlled with manganese sand
