OAKVILLE, Ontario, Canada, April 11, 2005 -- Zenon Environmental Inc. will supply the Yuhuan Power Plant, located in Zhejiang Province, China, with its immersed ultrafiltration water treatment technology. The company's ZeeWeed membranes will pretreat seawater before it is desalinated with reverse osmosis membranes.

The ultrafiltration system will produce 76,800 cubic meters per day (or just over 20 million gallons) of high quality feedwater, which will then be led to a desalination process for the production of 34,560 cubic meters per day of low saline water, once the plant is running. This site will serve as a key reference site for ZENON whose membrane technology is already producing higher quality effluent in industrial and municipal water and wastewater treatment plants around the world.

"We're very excited about this project, which is one of the world's largest installations of its type," said Andrew Benedek, Zenon chairman and CEO. "Our ZeeWeed technology is the ideal complement to extending the life and improving the performance of reverse osmosis membranes, particularly for seawater desalination."

The power plant will house four sets of 1,000 MW (mega watt) coal-fired steam turbine generators, which will be built in two phases. The first phase of construction is scheduled for completion in 2007 while the second is set to be commissioned in 2009.

Zenon is a world leader in providing advanced membrane products and services for water purification, wastewater treatment and water reuse to municipalities and industries worldwide.

In 2004, Corporate Knights, a business publication addressing corporate responsibility, ranked Zenon Environmental (www.zenon.com) as Canada's top Corporate Citizen, for the second time. Canada's Top 100 Employers ranked Zenon in their top 100 list for the last five years. An S&P/TSX Composite company, Zenon Environmental Inc. is publicly traded.
