摘要： A process of producing a composite semipermeable membrane which includes applying a polyfunctional amine solution and a polyfunctional acid halide solution in a hydrocarbon-based solvent having a flash point of not lower than 10.degree. C. on a surface of a microporous substrate to allow interfacial polycondensation reaction so as to form a cross-linked polyamide-based ultra-thin membrane superposed on the microporous substrate, then blowing a gas on the surface of the ultra-thin membrane so as to evaporate the hydrocarbon-based solvent, which gas has a velocity at the surface of 2-20 m/sec., a temperature of 10.degree.-80.degree. C. that is lower than the flash point of the hydrocarbon-based solvent, and an absolute humidity of not less than 1 g of water per 1 kg of dry gas.

摘要： A fluid separation apparatus comprising a bundle or bundles of a great number of permselective hollow fibers inserted into a casing and having both the ends fixed by tube sheets is disclosed. This bundle is composed of a great number of hollow fiber elements, each of which consists of one or two hollow fibers wound around by a spacer yarn composed of a textured yarn. This fluid separation apparatus is advantageously used as an artificial kidney.

摘要： Sterilization of a dialyzer, using a saturated and wet semipermeable membrane and irradiating said dialyzer in the presence of an antibacterial agent. The method is especially effective and safe, affords elimination of labor for preparation for dialysis, and has special utility when the dialyzer is an artificial kidney containing a multiplicity of hollow filament semipermeable membranes.
