Zenon supplies membranes for water reuse in China

Zenon won two contracts to supply ZeeWeed membranes for wastewater treatment in the Chinese capital, Beijing, and in Datong, the northern industrial centre for coal.

Zenon won two contracts to supply ZeeWeed membranes for wastewater treatment in the Chinese capital, Beijing, and in Datong, the northern industrial centre for coal. Both of these water-short cities will soon be treating wastewater using Zenon membranes and reusing the treated effluent. Together, the projects are worth more than US$ 6 million for the Canadian company Zenon.

Daton, located near Inner Mongolia in Shanxi Province, supplies approximately 40% of China's coal needs, and is also considered to be one of the largest coal mining centres in the world. Consequently, the production and sale of electricity is integral to the economy; however the supply of groundwater and surface water is limited. Existing supply is quickly depleting as government is restricting use and charging increasingly higher fees. Industry is increasingly turning to alternative sources for industrial water supplies.

Zenon's ZeeWeed membranes will be treating treating municipal wastewater for further reuse as cooling tower make-up water and boiler feed water in the Datong power plant. Project construction is already underway and is expected to be completed in August 2004.

The Beijing Yanshan Petrochemical Co. Ltd, located in Beijing, plans to reduce processing costs by reusing high quality water. By using ZeeWeed membranes for tertiary treatment of wastewater, the company expects to optimise water supplies and reduce discharge costs. Membrane treatment will improve the quality of treated effluent for reuse in the plant as process water and boiler feed water. The water treatment plant will be completed by July 2004, according to Zenon.
