We prepared a number of Alumina(Al2O3) microfiltration membranes fabricated using a wellestablished large throughput thermalspray(TS)technique.In order to study the filtration characteristics and performance of the thermal spray membranes,a variety of microstructures were fabricated by the varying spray process,deposition parameters and the source materials.We characterized the prepared membranes usingXRD(X-ray Diffraction),EDX(Energy dispersive X-ray Spectroscopy),SEM(Scanning
Electron Microscopy),pore size analysis and dead end filtration tests.Permeability and rejection rate of the sprayed membranes were comparable to some of the commercially available inorganic membranes with the advantage of being highly scalable and potentially orders of magnitude cheaper than the
commercially available ceramic membranes.
