Microbial Desalination Cell pilot

The Microbial Desalination Cell (MDC) technology integrates the Microbial Fuel cell (MFC) process and Electrodialysis (ED) to treat wastewater, desalinate saline waters and simultaneously produce electricity.

A typical MDC pilot contains three chambers separated with cation exchange membranes (CEM) and anion exchange membrane (AEM). The first chamber contains a anode, the second a cathode and in the middle there is a desalination chamber responsible for salt removal. The anode is responsible for waste water treatment by organic degradation and producing electricity.

The electrons flow from the anode to the cathode through an external electrical circuit. The electrons will be reduced by an electron acceptor at the cathode, causing potential difference between the anode and cathode side. The potential difference is the driving force to transport ions.

The performance of MDC will be measured based on the power density produced. The system can be combined with other desalination processes, such as Reverse Osmosis or Forward Osmosis
