Abstract: A method of producing a hollow fiber membrane includes discharging a polyvinylidene fluoride solution comprising a polyvinylidene fluoride resin and a poor solvent at a temperature above a phase separation temperature into a cooling bath at a temperature below the phase separation temperature to coagulate the polyvinylidene fluoride resin. The hollow fiber membrane comprises a polyvinylidene fluoride resin having spherical structures that have an average diameter in the range of 0.3 to 30 µm.

Abstract: A separation membrane having a porous substrate and a porous resin layer on at least one surface of the porous substrate and the porous resin layer contains a resin. Part of the resin permeates through the porous substrate to form a composite layer. At least one of the following relationships (1) and (2) is satisfied: (1) the porous resin layer has an average pore size in the range of 0.01 to 0.2 µm and a standard variation of the pore size of 0.1 µm or less at the surface, and (2) the porous resin layer has macrovoids having short diameters of 0.05xA or more wherein A represents the thickness of the porous substrate, and the rejection of microparticles having an average particle size of 0.9 µm is at least 90%. This separation membrane can be readily produced by a method for making a separation membrane according to the present invention.

Abstract: The invention provides a method of producing a chemical product through continuous fermentation which includes filtering a culture of a microorganism or cultured cells with a separation membrane to recover a product from a filtrate and simultaneously retaining a nonfiltered fluid in, or refluxing it to, the culture, and adding fermentation materials to the culture, wherein a porous membrane having an average pore size of 0.01 µm or more to less than 1 µm is used as the separation membrane and the filtration is conducted with a transmembrane pressure difference in the range of 0.1 to 20 kPa. According to this method, the fermentation productivity of the chemical product can be largely elevated at high stability and a low cost.

Abstract: Es wird eine semipermeable Verbundmembran bereitgestellt, die sich durch eine hohe Beständigkeit und hohe Entfernungsleistung gelöster Stoffe und eine hohe Wasserpermeationsleistung auszeichnet. Die semipermeable Verbundmembran wird aus einer porösen Trägermembran und einer Polymermembran gebildet. Die Polymermembran ist aus mindestens einer Sorte Polymer (a) mit einer positiven Ladung in einer Wiederholungseinheit und mindestens einer Sorte Polymer (b) mit einer negativen Ladung in einer Wiederholungseinheit, gebildet und hat eine vernetzte Struktur, die durch Siloxanbindungen zwischen dem Polymer (a) und dem Polymer (a), zwischen dem Polymer (a) und dem Polymer (b) und/oder zwischen dem Polymer (b) und dem Polymer (b) gebildet ist.
