Palladium alloy composite membranes for hydrogen separation have been fabricated on a porous stainless steel (SS) support by the vacuum electrodeposition and laminating procedure of thin palladium alloy film less than 25 mm. In spite of the formation of an alloy with copper, the brittleness of the p

Nickel hollow fiber membranes were prepared by a phase inversion and a sintering method. A nickel hollow fiber support was prepared by spinning the polymer solution containing suspended nickel powders to a hollow fiber precursor which is then sintered at elevated temperature. For these hollow fiber

Ultrathin alumina hollow fibers were prepared by a phase inversion and a sintering method. A polysulfone solution containing well-dispersed alumina powders is spun, which is then sintered at elevated temperature. To increase the packing density of alumina powers in the hollow fiber, 1,4-dioxane was

Fouling resistant membranes (NF and RO membranes) were prepared by coating a neutral polyvinyl alcohol (PVA membrane). The PVA-coated membranes showed a lower surface charge and roughness. By using the NF and RO membranes, dyeing process wastewater (influent, coagulated water and effluent) was recyc
