Comparison of filtration performances between membrane and non-membrane filters

摘要

The filtration performances of PE felt and PTFE laminated membrane PE felt are experimentally studied. Although membrane filter give a higher residual pressure drop than the non-membrane filter, the same filtration cycle times are obtained because membrane filter has a lower curvedly pressure drop increasing part resulting from a comparatively homogenous filter surface. The filtration efficiency and cake release of membrane filter are far superior to the non-membrane filter.
