抄録

Inorganic membranes and organic–inorganic membranes used for water treatment are reviewed. First, inorganic membranes are briefly introduced in terms of their advantages, manufactures, and materials. Second, some recent topics of inorganic membranes are summarized, including commercialized large–scale modules (180mm in diameter, 1,000/1,500 mm in length; 15/24 m2) which have been applied for drinking–water production. TiO2 nanoporous membranes with molecular weight cut–off in the range of 200 ～ 2,000 by sol–gel processing were successfully prepared, and applied to high temperature nanofiltration and possible “photo–cleaning” of foulants by photocatalysis. Finally, new applications of inorganic membranes are introduced, including carbon nanotube membranes with superpermeability and zeolite membranes for desalination. Organic/inorganic hybrid membranes in RO/NF and UF/MF are also summarized.
