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

Abstract

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