Pierre L Cote, Bradley M Smith, Ake A Deutschmann, Carlos F F Rodrigues, Steven K Pedersen: Frameless array of hollow fiber membranes and method of maintaining clean fiber surfaces while filtering a substrate to withdraw a permeate. Zenon Environmental, Alfred D Lobo, September 28, 1993: US05248424 (157 worldwide citation)

A frameless array unconfined in a modular shell, proves to be a surprisingly effective membrane device for withdrawing permeate from a substrate, the flux through the membranes reaching an essentially constant relatively high value because of the critical deployment of fibers of the array as a skein ...
