Water flux and salt permeate concentration for 24 h operation by DCMD on 35 g/L NaCl solution: (a) (S1) PVDF 14 wt.% with water, (b) (S2) PVDF 14 wt.% + LiCl with water, (c) (S3) PVDF 16 wt.% + LiCl with water, (d) (S4) PVDF 18 wt.% + LiCl with water, (e) (S5) PVDF 16 wt.% + LiCl with water (90%) + EtOH (10%), (f) (S6) PVDF 16 wt.% + LiCl with water (80%) + EtOH (20%), and (g) (S7) PVDF 16 wt.% + LiCl with water (70%) + EtOH (30%). For all DCMD experiments, the feed and distillate temperatures were 60 and 20 °C, respectively.
