About the Practice
Problem Statement:

Energy-efficient combined process of microbial fuel cell (MFC) and membrane bioreactor (MBR) for high efficiency and reliable treatment of organic wastewater


A two-stage continuous process is developed, combining MFC and submerged MBR, with intermittent suction of high-quality effluent through an ultrafiltration membrane, which can be used for treatment of sewage as well as medium-strength industrial wastewater and consequently generate high-quality effluent and bioelectricity in this process. The air-cathode MFC is constructed with a low-cost ceramic cylinder, considered as the anodic chamber. Acetone is used as a mixing solvent. Untreated carbon felt is used as anode and cathode current collector. The MFC is kept in an open environment under the influence of fluorescent light. Synthetic wastewater with sucrose as a carbon source is introduced in MFC and effluent is continuously collected in the aerobic MBR. Further, a submerged hollow fiber-ultrafiltration unit is attached inside the aeration tank and effluent extraction is carried out under constant membrane flux. The effluent is then collected in an aeration tank as a carbon/nutrient source for aerobic microorganisms.
