This book covers advances in fabrication, characterization and applications of low-cost ceramic membranes, especially using natural minerals and industrial wastes.  Multiple aspects on design and selection of both materials and fabrication processes have been explored to identify the prospective formulations for manufacturing low-cost membranes primarily based on cheaper sources of alumina and silica. The contents further highlight  the developments towards commercialization of low-cost ceramic membranes including the way forward to address the future challenges by the researchers. The prohibitive cost of ceramic membranes manufactured from synthetic powders restricts their wide spread applications in spite of  some unique performance advantages of ceramic membranes for separation under harsh and challenging conditions. In this context, the focus on development of such newer generation ceramic membranes assumes significant importance and offers immense potential  in extending the scope of applications of low-cost ceramic membranes. This book is beneficial to academics and practitioners alike.
