  • Theoretical framework for predicting inorganic fouling in

    Calcium sulfate, one of the two most common salts that foul in membrane distillation, was used as a model foulant under supersaturated conditions. To form supersaturated CaSO 4 solutions, two component salts, CaCl 2 and Na 2 SO 4 (ACS grade, Sigma-Aldrich), were dissolved fully and added one at a time (about 10 min apart) to allow for thorough
