Various ultrafiltration and nanofiltration membranes were characterized by solute transport and also by atomic force microscope (AFM). The molecular weight cut-off (MWCO) of the membranes studied were found to be between 3500 and 98,000 Daltons. The mean pore size (μ p ) and the geometric standard deviation (σ p ) around mean ranged from 0.7 to 11.12 nm and 1.68 to 3.31, respectively,...
