文摘

Mass transfer mechanisms of ED for liquid desiccant regeneration are investigated. Water flux due to osmosis and electro-osmosis was significant and cannot be ignored. The applied current is the most influential factor of salt flux through membranes. Water flux due to electro-osmosis increases with decreasing initial concentration. Concentration difference between the two streams of solutions should be minimized.
