Direct contact membrane distillation mechanism for high concentration NaCl solutions

Using high concentration NaCl aqueous solutions, direct contact membrane distillation (DCMD) experiments are implemented in this work where water fluxes are measured at different feed/permeation temperatures, feed concentrations and flow rates. The results under the experimental conditions show that (1) water fluxes decrease as concentrations of NaCl solutions increase; (2) when concentrations of NaCl solutions are above 25%, water fluxes...
