ABSTRACT:
Microporous hollow fiber polysulfone membranes can be prepared continuously by using a particular combination of casting solution and precipitation solution formulations, and casting conditions. The concentration of components in the precipitation solution are adjusted continuously to maintain original concentrations. The membranes are characterized by high quality, consistent performance and uniform porosity throughout the membrane.
