Sažetak
The objective of this study was to show how two distinctive experimental RO/NF membrane characteristics could be used to describe the porosity of the membrane’ s active layer without resorting to theoretical models. Two characteristic parameters: the susceptibility of the active layer structure under pressure α and the membrane’ s pure water permeability K’ , were determined from the membrane’ s flux dependency on pressure. 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 into three groups according to the values of the characteristic parameters.
