Patent number: 7303676Abstract: A membrane supported biofilm reactor uses modules having fine, hollow fibres, for example, made from melt spun thermoplastic polymers treated after spinning to increase their permeability to oxygen, used, for example, in tows or formed into a fabric. In one module, one or more sheets of the fabric are potted into a module to enable oxygen containing gas to be supplied to the lumens of the hollow fibres. Various reactors and processes, for example to treat wastewater, using such modules are described. Mechanical, chemical and biological methods, for example endogenous respiration, are used to control the thickness of the biofilm.Type: GrantFiled: July 22, 2004Date of Patent: December 4, 2007Assignee: Zenon Technology PartnershipInventors: Hidayat Husain, Pierre Lucien Cote, Ian Glenn Towe, Henry Behmann, Ian Alexander Pottinger

Patent number: 7300571Abstract: A membrane supported biofilm reactor uses modules having fine, hollow fibers, for example, made from melt spun thermoplastic polymers treated after spinning to increase their permeability to oxygen, used, for example, in tows or formed into a fabric. In one module, one or more sheets of the fabric are potted into a module to enable oxygen containing gas to be supplied to the lumens of the hollow fibers. Various reactors and processes, for example to treat wastewater, using such modules are described. In one process, oxygen travels through fibers, optionally through an attached biofilm, to oxygenate surrounding water. Mechanical, chemical and biological methods, for example endogenous respiration, are used to control the thickness of the biofilm.Type: GrantFiled: August 15, 2005Date of Patent: November 27, 2007Assignee: Zenon Technology PartnershipInventors: Pierre Lucien Cote, Hidayat Husain, Ian Glenn Towe, Henry Behmann, Ian Alexander Pottinger
