On experimental parameters characterizing the reverse osmosis and nanofiltration membranes’ active layer
The objective of this study was to investigate distinctive reverse osmosis (RO)/nanofiltration (NF) membrane characteristics that could be used to describe the porosity of the membrane’ s active layer without resorting to theoretical models. From the membrane’ s flux dependency on pressure, two characteristic parameters were determined: (1) the susceptibility of the active layer structure under pressure and (2) the membrane’ s pure water permeability. The significance of the characteristic parameters was confirmed by relating them to the pore size distributions (PSD) and to the effective number of pores, N in the active membrane layer. The examined RO/NF membranes were classified according to the values of the characteristic parameters, and the classification was illustrated by determining the membranes’ rejection properties for various, mostly organic solutes.
