Herein, we systematically investigated the influence of membrane structural properties on limiting flux behavior and selectivity loss during gypsum scaling in osmotically driven membrane processes. We selected two typical osmotic membranes, thin-film composite (TFC) polyamide (PA) membrane and integ...
