Question
MF membranes are usually ________ where as UF membranes are _________. Symmetric and symmetric Symmetric and anisotropic Anisotropic and anisotropic None of these
Solution
The correct answer is "Symmetric and anisotropic". Microfiltration (MF) membranes are usually symmetric, meaning they have the same material properties throughout. Ultrafiltration (UF) membranes, on the other hand, are typically anisotropic, meaning they have different properties in different directions. This is because UF membranes often have a thin, dense layer for separation on top of a porous, support layer.
