4- Membrane Thickness and Strength
Mechanical strengths of membranes vary by material, structure, and manufacturing process. This is true even when the membrane thicknesses are similar. Hollow fiber UF membranes usually have a wall thickness of 150-300 μm. The wall thicknesses of MF hollow fiber membrane manufactured with elongation process, are normally 50 μm to 100 μm but have similar strength properties as UF hollow fibers.
