Microbial desalination cell (MDC) is a new technology that employs bacteria to convert organic matter to electricity and use the potential gradient to drive in situ desalination. Compared to current energy intensive wastewater treatment and reuse technologies, MDC provides multiple benefits by integrating wastewater treatment, net energy production, and desalination into one single system. This new technology demonstrates great application potentials in wastewater and desalination industry. This article summarizes our recent findings on MDC system development, reactor performance in various conditions, membrane and ion transfer characterization, as well as future directions.
