In order to calculate permeate mass flux, Equation 1 was used.

Equation 1
Where is the permeate flux; and are the time; is the increase in the permeate mass between times and ; and is the membrane area.
To estimate the expected flux, Equation 2 was used [30]. Equation 2
In the previous equation, is named membrane coefficient; is the mass flux across the membrane; and is the vapour pressure difference between both interfaces. For the different liquid-gas phase equilibria states of water, its vapor pressure relates to temperature as shown in Equation 3 [30]. Equation 3
For the calculation of the resistances, Equations 4 to 6 were used [31]. Equation 4 Equation 5
