and is growing at 6% annually on average.
These estimates are from US-based Business Communications Co (BCC), the host of the '21st Annual Membrane/ Separations Technology Planning Conference', to be held in Newton, Massachusetts, USA, 1-2 December 2003.
BCC said membranes remain vital to government and industry as evidenced by their range of applications in potable water production; pollution control; power generation; foods and beverages; pharmaceuticals, biotech and medicine; semiconductors and chemicals. It said new materials, products and processes continue to emerge as membrane scientists strive to enhance separation speed and selectivity and improve membrane properties for non-separating uses.
BCC said rapidly growing sectors in some well-established markets, as well as promising developing applications, were propelling growth in the membrane market. It said issues of quantity, quality and ageing infrastructure were driving the municipal drinking water/wastewater market, a field where membranes offer 'green', efficient and cost competitive treatment.
In emerging applications, BCC said the billions of private and government dollars pumped into fuel cell research were finally resulting in commercial products with a vast potential for membrane use. It said gas separations, with a particular emphasis on hydrogen to power the fuel cell future, were also in demand. In the medical field, the company pointed to new membranebased artificial organs, such as liver, lung and pancreas, as a potential large new market.
