Mechanical Properties of Membrane Elements

Most inorganic membranes are mechanically stronger than their organic counterparts. However, installation, repair and maintenance, mechanical vibration, pressurization and other application conditions sometimes can cause problems. This is especially true with 

Based on available product brochure information of commercial membranes and the literature data of developmental membranes. Table 5.5 provides some indication of the various mechanical properties of a few inorganic membrane elements. It should not be used for serious comparison as the testing conditions are usually not given or sketchy at best. In addition, the mechanical properties of a membrane element depend, to a great extent, on its shape, membrane thickness, porosity and pore size. While overall the majority of the data appears to be consistent, there is some strength data that seems to be off the trend line.
