Conventional wastewater treatment methods can be replaced by adopting MFC. The organized project conducted satisfactorily represents MFC as a convincing technology to treat dairy effluent along with generation of energy. The primary object of the existing paper “Treatment of Dairy Wastewater using MFC Employing Zinc Electrode” is to examine the efficiency of dual chambered MFC having continuous feed of substrate. The substrate employed is dairy effluent. The developed design parameters are established by checking out the responsibility of employing silver nanoparticles integrated salt bridges, Zinc electrodes and altering detention time. Zinc electrode having surface area of 123.4 sqcms is finding to be most stable performer. The detention time of six hours is found to be optimum for maximum output. For optimized experimental set up the maximum efficiencies obtained in removal of COD, BOD, EC, TDS and Oil and Grease were 77.58%, 75.02%, 65.95%, 57.96% and 67.32%. Maximum power and electrical energy generated were 21.483 μW and 0.0386694 Watt-sec respectively. From the results obtained the conclusion was MFC is efficient in replacing conventional method of treating dairy wastewater. It can treat efficiently along with energy generation.
