Plant microbial desalination cell: in-situ salt removal without an external energy input

Fresh water is becoming scarce. Our ever increasing population results in a higher demand of fresh water for drinking purposes, irrigation and use in industries. These demands are becoming greater than the Earth’s natural reserves can supply. The quality of water needed can however vary for different applications and complete deionization or purification of water is not always needed. The plant microbial desalination cell (Plant-MDC) could offer a partial desalination treatment of salt (waste) water.

The technology can be applied in all (constructed) wetlands without harming the ecosystem or altering the aesthetics of the area. And since no external energy storage or input is necessary, the technology can be applied in remote areas without electrical infrastructure, keeping the costs low.
