Micro and ultrafilters with controlled pore sizes and pore size distribution and methods for making
摘要:
A micro/ultrafiltering element (10) and method for making a filter element are provided. The filtering element comprises a multi-level support (26) having a filtering membrane layer (12) formed thereon comprising sintered particles (14) of uniform diameter. The filtering membrane preferably has an average pore size of from about 0.005-10 micrometers. The filter element is capable of being formed in a variety of geometrical shapes based on the shape of the porous support,
