Abstract: Abstract 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)… read more here.

Abstract: Abstract Although membrane distillation (MD) has great potential in treating high-salinity wastewater, continuous accumulation of inorganic salt due to increasing concentration inevitably causes supersaturation and subsequent membrane scaling. Crystallizer is an effective tool used for… read more here.

Abstract: Abstract Precipitation of calcium sulfate dihydrate (i.e., gypsum) on the membrane active layer negatively impacts the efficiency of reverse osmosis (RO) systems by increasing overall operation and maintenance costs. The interfacial free energy between RO… read more here.

Abstract: Mineral scaling is a major constraint that limits the performance of membrane distillation (MD) for hypersaline wastewater treatment. Although the use of antiscalants is a common industrial practice to mitigate mineral scaling, the effectiveness and… read more here.
