The permeate flux along the osmotic evaporation process is shown
in Fig. 3. The fluxes were significantly lower than those obtained in
the reverse osmosis process, ranging from 1.55 L h−1 m−2 to
0.01 L h−1 m−2. Similar fluxes were observed by Pagani et al.
(2011), Vaillant et al. (2005) and Cissé, Vaillant, Perez, Dornier, and
Reynes (2005), in the osmotic evaporation of acerola juice , melon, and orange
juices, respectively.
