Abstract

CTA-based membranes for forward osmosis (FO) were prepared by immersion precipitation. Casting composition and coagulation conditions—solvent/acetone ratio, temperature, evaporation time of coagulation bath—were optimized to obtain membranes with best performance. Membranes were characterized by various available methods to testify the performance in forward osmosis system. The CTA membrane showed a water flux higher than 3.8 LMH and a good NaCl rejection of 95% when using 2 M glucose solution as the draw solution and 0.6 M NaCl solution as feed solution. Besides, experiments were attempted to remove microcystin by applying FO technology. More than 80% of the microcystin removal rate was obtained in this experiment.
