In this paper, we report a method to improve the power generation using brines discharged from two different membrane-based desalination processes. We modified a RED model proposed by Veerman and co-workers, and this modified model was in agreement with experimental results. We considered river water and seawater as the diluted solutions for RED. The power density with RO (1.48 W/m(2)) and FO (1.86 W/m(2)) increased 1.5-fold and 2-fold, respectively, compared with that using seawater. When seawater was used as the diluted solution, the RED power decreased considerably. We characterized the RED performance using the intermembrane distance and the inlet flow rate. The power generated monotonously increased with decreasing compartment thickness and increasing flow rate. The net power had a specific optimal value because of a drastic growth in the pumping power. In our system, the optimal intermembrane distance was 0.1 mm (RO brine) and 0.3 mm (FO brine). We also computed the energy cost owing to RED. The results showed that the energy consumption could be lowered by similar to 7.8% from the typical value for RO. We found a drastic decrease for FO with the energy consumption lowered by similar to 13.5%. (C) 2015 Elsevier B.V. All rights reserved.
