Bioelectrochemical technologies offer alternative ways of treating wastewater and using this process to generate electricity. However, research in this area is just beginning to consider environmental transmission of viruses present in wastewater. The viral fecal indicator coliphage MS2 (the most frequently used pathogen model) was used in this study, since it is a well-known indigenous wastewater virus. The scaled-up bioelectrochemical system had a working volume of 167 L and coliphage MS2 concentration decreased from 8000 to 285 PFU/mL. The kinetics were quantified up to 15 h, after which excessive yeast growth in the system prevented further bacteriophage determination. The logarithmic reduction value (LRV) calculated within the first three hours was 3.8. From 4 hours to 14, LRV values were from 4.1 to 4.8, and in hour 15 the LRV increased to 5.3, yielding a more than 90% reduction. Overall, results obtained indicate that the scaled-up bioelectrochemical treatment system was efficient in reducing coliphage MS2 densities and could be used as a model to explore its further applicability for the reduction of viruses or pathogens in treated effluents.

Bioelectrochemical System

Microbial Fuel Cell (MFC) is a bioelectrochemical system that utilize metabolism of microorganisms to produce electrical energy. Microbial fuel cell is a bioelectrochemical system involving redox reactions that required an oxidizing agent in the process The purpose of this study was to determine the effect of various concentration of electrolyte solution KMnO4 and K3[Fe(CN)6] on electricity produced by microbial fuel cell system with Lactobacillus bulgaricus in tofu whey substrate. The principle of this study was bioelectrochemistry that changes chemical energy into electrical energy which involves a redox reaction by utilizing microbes. This study used a microbe Lactobacillus bulgaricus and substrate tofu whey with 0.39 % carbohydrate content in dual chamber MFC system using a salt bridge as a conductor of protons from anode to cathode. Anode compartment contains a mixture of microbes that have been cultured and phosphate buffer with pH 7 while cathode compartment contained electrolytes KMnO4 or K3[Fe(CN)6] in some various concentration that is 0.25 M; 0.2 M; 0.15 M; 0.1 M and 0.01 M with added potassium phosphate buffer pH 7. The MFC system using Lactobacillus bulgaricus and substrate tofu whey with 0.39% carbohydrate content and electrolyte solution KMnO4 generated maximum potential difference of 99.2 mV at concentration of 0.2 M which was higher than system with electrolyte solution K3[Fe(CN)6] 0.2 M that produced maximum potential difference of 48.6 mV.
