While there have been major advancements in affordable water filter technology which removes biological contaminants, many of these filters go unused in developing countries because these filters still do not filter out saline, making water much less consumable.

Natasha Wright invented a solar powered desalination system to remove salt from ground water. This system uses electrodialysis to separate ions from the water stream. Electrodialysis requires far less energy compared to most desalination systems in developing countries.
