Abstract

A method and apparatus for optimizing parameters of a hollow membrane filter results in a relatively small filter when a predetermined, substantially constant, driving pressure drop is applied between the inlet and the outlet of the filter. The method includes simultaneous solution of a set of equations to specify fiber length, number and internal diameter. A system including a computer can make optimized filters in response to the determined parameters.
