Sumitomo Chemical has developed a technology that improves permeance while maintaining separation performance in ceramic separation membranes (microfiltration membranes). The technology uses the Company’s high-performance alumina developed for separation membranes (the “newly developed alumina”) to increase the density of through-pores (*1) in the membrane structure.
This technology offers a new solution to a trade-off in separation membranes, in which improving permeance can reduce separation performance.
