32 View From March 2017 Water.desalination+reuse AMTA Hall of Fame 2017 HELIX MEMBRANE • X-Flow's Helix "tubular membrane with a twist" increases turbulence at the membrane wall to enhance fl ux, increase fl ow and save energy • The greater turbulence helps prevent the buildup of foulant and cuts energy consumption in high-solids ultrafi ltration • The technology was tested for a year at an Airli membrane bioreactor plant at Ootmarsum in the Netherlands • It delivered a 40 per cent overall improvement in output fl ow fl ux performance – from 50 l/m2h to 70 l/m2h – compared with the original crossfl ow confi guration And the winners are… • William Andrews • Charlie Hull • Srinivasa Sourirajan • Mike Stefanic A ra of industry awards was unveiled at the Membrane Technology Conference 2017, including AMTA's four-strong Hall of Fame 2017, recognising pioneering careers in membrane technology. This year's awards went to William Andrews, Charlie Hull, Srinivasa Sourirajan and Mike Stefanic for their contributions. Andrews was a Rhodes Scholar in philosophy and atomic physics, and began his career in the water industry working in electrodialysis. He joined Polymetrics in 1975, went on to found DesalCo in Bermuda in 1991, and in 2002 invented the Dual Work Exchanger Energy Recover Device, which continues to be one of the world's most energy- e‹ cient recovery devices for seawaterŒdesalination. Hull was recognised as a designer of signiŽ cant membrane facilities. He started out at Reverse Osmosis General Atomic (ROGA), designing breakthrough systems including the Ocean Reef Club (1971), Orange County Water Factory 21 (1976), and Four Corners New Mexico (1978). Hull moved on to Ajax International, and in 1983 founded Separation Engineering, where he continues to work. Srinivasa Sourirajan was given the Hall of Fame award for his signiŽ cant contribution to membranes. In 1960 he co- invented the original cellulose acetate RO membrane with the late Sidney Loeb. Moving to Ottawa, Canada, he went on to research the mechanism of reverse osmosis (RO), and developed alternative materials for RO and ultraŽ ltration. He was credited on more than 290 papers on membrane separationŒtechnology. Stefanic was honoured for his contribution, which included being one of the Ž rst engineers to recommend and install an RO system at an IBM semiconductor facility in New York, US. A er that, Stefanic joined Aqua Media and helped to spread the technology through- out the semiconductor indus- try, making it indispensable to operations. He continued to promote membranes while working at Fluid Systems/Koch, and Toray. "The membrane industry as we know it would not exist without Dr Sourirajan's breakthrough."
