Sažetak
The growing demand for water of a high quality has significantly increased interest in membranebased technologies. Reverse osmosis (RO) is a sustainable water treatment technology and the predominant technology in the desalination market in the last ten years, but still faces drawbacks, such as the relatively low water permeability of current composite commercial membranes that have been used for decades. The trade-off between selectivity and permeability is well known for RO membranes, i.e. highly permeable membranes lack selectivity, and there are several ways to overcome this trade-off. Post-solvent treatment is an economically viable and efficient method and is often used to improve membrane performance. The objective of this study was to determine the effects of solvent activation on water permeability, rejection of NaCl and CaCl2, and change in pore size/pore size distribution of brakish water RO membranes. 1-propanol (n-PA) showed the highest increase in water permeability (up to 73%) among the selected solvents, with no significant effects on rejection of NaCl and CaCl2. The improvement in performance was attributed to the change in pore size/pore size distribution after the membranes were exposed to the selected solvent.
