Cellulose acetate (CA) flat sheet membranes were fabricated and evaluated in a forward‐osmosis process. Effects of CA concentration, coagulation bath temperature, and annealing thermal treatment on both membrane structure and performance were investigated. NaCl rejection of the optimum membrane was determined utilizing a reverse‐osmosis setup based on conductivity measurements. Two validated models were obtained by means of response surface methodology based on Box‐Behnken design. The optimum operating pressure, temperature, and draw solution concentration were assessed as well.
