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 (153 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 ...

Steven K Pedersen, Pierre Lucien Cote, Nicholas Willam Harcsar Adams: Membrane module with multiple bottom headers and filtration process. Bereskin & Parr, September 23, 2010: US20100237014-A1

A membrane module (100) has an upper header.(108) and multiple lower headers (110). A bundle of membranes (24) potted in the upper header is sub-bundled into the lower headers. The membranes (24) may be arranged in the upper header into a number of generally parallel sheets or planes and arranged in ...

Steven K Pedersen, Pierre Lucien Cote, Simon Levesque: Hollow fibre membrane module. BERESKIN AND PARR SENCRL, November 12, 2009: US20090277826-A1

A module has a housing and a tube-sheet. Hollow fiber membranes are potted in the tube-sheet with their ends open. Mechanical interference prevents excessive movement of the tube-sheet along the length of the housing. A gasket is placed in a groove between the tube-sheet and the housing, opening tow ...
