Developing Intelligent Selective Electrodialysis for 21st century Agriculture
John H. Lienhard V, Abdul Latif Jameel Professor of Water and Food, and Director, Abdul Latif Jameel World Water and Food Security Lab
Period of performance:
September 2017 to August 2018
The Lienhard lab is developing a technology that could improve agricultural practices and crop yield, especially for hydroponic growers. The system is called Intelligent Selective Electrodialysis (ISED) and can be used to reduce water salinity. This process also tailors the ion content of irrigation waters to meet crop nutrient requirements and increase yields. An improvement on existing reverse osmosis desalination processes, ISED selectively removes the ions that are harmful for crops and retains those that are beneficial, resulting in improved yield with less water and fertilizer use. The team plans on using this grant to conduct end-user interviews in the US and Mexico and test their lab prototype.
