VALLEJO-CASTANO, Sara  and  SANCHEZ-SAENZ, Carlos Ignacio. Design and optimization of a reverse electrodialysis stack for energy generation through salinity gradients. Dyna rev.fac.nac.minas [online]. 2017, vol.84, n.202, pp.84-91. ISSN 0012-7353.  https://doi.org/10.15446/dyna.v84n202.59321.

A model for design of Reverse Electrodialysis stacks for energy generation is presented and solved. A new optimization function is proposed for RED, which accounts for river water consume, net power density and thermodynamic efficiency of the process. The parameters of residence time and thickness of the compartments are successfully optimized using the new proposed function. Results suggest small residence time, compartments thickness, and transversal area and Long/Width ratio for maximum energy generation.
