Sumitomo Chemical Develops High-Performance Alumina to Enhance the Permeance of Ceramic Separation Membranes
Sumitomo Chemical/JP 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 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. The mechanism of this technology was demonstrated through joint research with Kobe University. The findings were published online in Journal of Membrane Science Letters, a scientific journal, on August 12, 2026.
The results of the study indicate that the newly developed alumina provides new guidance for developing high-performance separation membranes for applications that are prone to the adhesion and accumulation of contaminants. Such applications include food processing, biotechnology, fermentation, chemicals, and wastewater treatment. Going forward, Sumitomo Chemical will propose solutions that contribute to higher value-added products, improved filtration system performance, and more stable operations for membrane and filtration system manufacturers. Sumitomo Chemical is committed to becoming a company that solves societal challenges through innovative technologies. It will continue to provide solutions to challenges across a wide range of industrial fields through innovative technologies.
