Effects of hydrophobic silica additives on the structure and performance of PVDF membranes for liquid filtration

Membrane fouling isa main challenge in most pressure driven membrane processes. Improving membrane surface characteristics plays an important role in fouling mitigation efforts. Although hydrophilic additives are often used as effective pore formers, employing hydrophobic additi...
