Praxair, Inc. (Danbury, Conn.; www.praxair.com) continued to execute its strategy of providing environmental solutions for growing water treatment applications in China. The company recently started up two vacuum pressure swing adsorption (VPSA) oxygen supply systems for Jiangbin Water Treatment Co., Ltd, and the Gao Bei Dian Recycling Plant. Praxair also signed a long-term contract with the Xiao Hong Men water recycling plant to build, own and operate a VPSA system for its water-treatment processes.
Jiangbin Water is located in Shaoxing, Zhejiang province, China, the industrial hub of the country’s textile and dye industry. The company is the first large-scale plant in the country to use the ozone process to treat discharge from dye and textile finishing processes. The VPSA system produces the oxygen required to manufacture ozone.
Gao Bei Dian and Xiao Hong Men, part of the Beijing Drainage Group, are two of the largest municipal water recycling facilities in Beijing. The new Praxair VPSA systems will supply ozone units that decolor and disinfect water, helping mitigate water shortages and supporting the city’s sustainability efforts.
With a long-term commitment to engineering, project execution and operations expertise, Praxair is at the forefront of VPSA research, developing new technologies to better meet the changing needs of customers.
