Ethanol / Water Separation Technology is a long term research. LTA molecular sieve, which is an industrially important desiccant as a kind of zeolite molecular sieve. It is always used in the reverse osmosis method, which is one of the sea water desalination, and extraction of industrial ethanol method in the world. Membrane separation technology is widely used in cell science[1, 2], human science[1, 2], microbial science[3], military industry, battery technology[4, 5] and so on. With 2 years invention and attempts, prototype membrane is finished and the filtered data has also been measured in different side, such as Linda Type A(LTA) making temperature, raw material ratio of membrane preparation and filter curves. The physicochemical analysis of the samples before and after filtration was carried out. The manbrane filtration losses are very low and can be used with food grade filtration
