Effect of Methylene Blue Addition as a Redox Mediator on Performance of Microbial Desalination Cell by Utilizing Tempe Wastewater

Fachryan Zuhri, Rita Arbianti, Tania Surya Utami, Heri Hermansyah


Abstract: The microbial
desalination cell (MDC) is a modification of the microbial fuel cell (MFC)
system. The microbial desalination cell is a sustainable technology to
desalinate  saltwater  by directly 
utilizing  the  electrical 
power  generated  by 
bacteria  during  the oxidation process of organic matter. In
this study, tempe wastewater will be
used as a substrate.  Methylene blue (MB)
at concentrations of 100 μM, 200 μM, and 400 μM in the anolyte is added as a
redox mediator, and the effect on electricity production and desalination
performance are evaluated. The average power density increases by 27.30% and
54.54% at MB concentrations of 100 μM and 200 μM, respectively. On the other
hand, the increase of the MB concentration in the anolyte results in a decrease
in the salt removal percentage. The observation made using a scanning electron
microscope showed the presence of MB adsorption on the surface of the anion
exchange membrane (AEM) and is suspected to be the cause of the disruption of
anion transfer between MDC chambers causing a decrease in the salt removal
