Electrode Distances Of Microbial Fuel Cell System On Salted Boiled Fish Processing Wastewater To Electricity And Pollution Load
AbstractMicrobial fuel cell (MFC) is a technology produce electricity by helping exoelectrogenic bacteria. The
technology can also utilize fishery processing wastewater as a media for bacteria to live, so it reduces organic
pollution load in the wastewater. The 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 applied 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.
