2. Summary 

The current paper has various lessons as follows; 
First, an approximated version of water flux model can be occasionally a good alternative to the original one. 

Due to its complexity and non-linearity, the calculation of the water flux models has required intricate numerical analysis procedures.

However, it was demonstrated, in the range of low-salinity, that the water flux model approximated by the Taylor expansion also shows a good performance.

Second, the effects of co-current and counter-current flows on a PRO process were analyzed.

The differences which are made between the co-current and counter-current flows were concretely analyzed by setting boundary conditions.

Third, the difference between the co-current and counter-current flows is not huge rather than our stereotypes.

Even though the performance discrepancy between the counter-current and co-current configurations are well-recognized to researchers, we just opaquely guess the difference those two configurations. In this paper, the authors rediscovered that the distinction of performances between the co-current and counter-current configurations is not that huge.
