membrana de pervaporação de cerâmica e membrana de cerâmica permeável ao vapor

摘要

A ceramic pervaporation membrane and a ceramic vapor-permeable membrane where the total aperture length of discharge channels parallel to the channel direction of water collection cells is at least 10% of the length of filtration cells and where the ratio m/n of the number m of rows of filtration cells to the number n of rows of water collection cells is between 1 and 4 have a high water permeation rate and a high separation coefficient.
