Comparison of the intrinsic parameters (A, B, and S) of a forward osmosis membrane using pressurized and non-pressurized methods

Generally, forward osmosis (FO) membrane performance is defined based on its intrinsic parameters, namely the water permeability (A), solute permeability (B), and structural parameter (S). This study was conducted to examine the performance of the commercial membrane NF2 in an FO system and to valid...
