Abstract

Microbial Desalination Cell (MDC) is a developed technology for reducing salt concentration of seawater, so it could be used for people's daily needs. Since there were many tofu industry in Indonesia, so that the substrate in this research came from model of tofu wastewater. For increasing MDC performance, there was modification in reactor design, whereas the IEM (Ion Exchange Membrane) was arranged in two stacked design, yet in the end of desalination cycle there was a recirculation through anolyte-catholyte solution to maintain pH level. The variations of flowrate recirculation were 0.5 and 5 mL/ min. The result showed that the optimum flowrate for anolyte-catholyte recirculation was 0.5 ml/minute with TDR (Total Desalination Rate) of 2.447 g/h and it showed that recirculation process could increase the salt removal of desalination process.
