Abstract
Abstract Bio-electrochemical technology in form of single chamber microbial fuel cell was used to simultaneous reduce organic pollutants and electricity generation under anoxic condition. Reactor was fixed working volume 1liters. Single chamber microbial fuel cell was started with open circuit that inoculates to biofilm on anode chamber and microorganisms can be adjusted to single chamber microbial fuel cell condition. Close circuit was started with 1,000 ω. Initial COD was converted to 5,109 mg L −1 that obtained current density per area 154 mA m −2 , maximum power density per area 152 mW m −2 and COD removal efficiency was 70%, respectively. Moreover, the economic feasibility was evaluated in term of net present value (NPV) was 1,746.20, payback period (PBP) was obtained 1 year 4 months, respectively. Therefore, single chamber microbial fuel cell is technology that suitable for simultaneous reduce organic pollutants and electricity generation.
