OAKVILLE, Ontario, Dec. 20, 2000 (BUSINESS WIRE)—Communities in Alberta, Oregon, New Hampshire and Texas have all selected ZENON's (TSE:ZEN.)(TSE:ZEN.A.) ZeeWeed® membrane technology as the preferred solution to providing their residents with clean, reliable water. These projects total approximately $20 million for drinking water and wastewater plants expected to be built in 2001. Unlike conventional methods of filtration that use chlorine to kill or inactivate certain contaminants, membranes provide superior water quality by filtering out unwanted particles. ZENON's ZeeWeed® membranes, in addition to removing water-borne bacteria and viruses, also remove parasites such as cryptosporidium and giardia, which are resistant to chlorine and remain active in the water stream. The market for water treatment products has increased recently due to the heightened public awareness of water quality issues in municipal drinking water infrastructure.
