Electrode Distances Of Microbial Fuel Cell System On Salted Boiled Fish Processing Wastewater To Electricity And Pollution Load

Microbial fuel cell (MFC) is a technology that can produce electricity with helping exoelectrogenic bacteria. The technology can also utilize fishery processing wastewater as a media for bacteria to live, so it can reduce organic pollution load in the wastewater. Purpose of this research was to identify the effect of electrodes distance to electricity and water quality parameters of fisheries processing wastewater using MFC technology.. The MFC system used was single chamber system. The distance between electrodes used were 2 cm, 4 cm and 6 cm and the electrodes were made of stainless wire mesh coated with chitosan and active carbon. The results showed that electrodes distance affected to MFC electricity within salted boiled fish wastewater media. The average value of electric current during 48 hours observation on the distance of 2 cm, 4 cm and 6 cm were 0.17±0.06 mA, 0.46±0.17 mA and 0.44±0.16 mA, respectively. Average values of electric voltage on the distance of 2 cm, 4 cm and 6 cm were 0.12±0.03 V, 0.34±0.07 V and 0.37±0.08 V, respectively. The research also showed that MFC system can decrease average value of BOD 20.5%, COD 30.41%, and TAN 21.2 % of salted boiled fish wastewater media.
