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
