Three-chambered microbial desalination cells at work
Desalination plants generally employ one of two methods to produce clean water – reverse osmosis or electrodialysis. Unfortunately, both processes require large amounts of energy, but an international team of researchers has proven a process that cleans wastewater can also remove 90 percent of salt from brackish water or seawater while generating electricity.
