Praxair, through its subsidiary Beijing Praxair Inc., has signed a long-term gas supply contract with Gao Bei Dian Water Recycling Plant of Beijing Drainage Group Co., Ltd.

Praxair will build, own and operate a vacuum pressure swing adsorption unit to supply gaseous oxygen to the plant for its wastewater treatment and recycling processes.

Located in downtown Beijing, the Gao Bei Dian recycling plant is the largest in China, with capacity to process one million tons of recycled water per day. The plant treats wastewater from municipal drainage and uses the recycled product as cooling water for local power plants as well as for landscaping needs throughout the city. The plant plays a major role in Beijing Municipality’s Wastewater Treatment and Recycled Water Use Project, helping to mitigate water shortages and supporting the city’s sustainable development efforts.

“We appreciate the trust that Beijing Drainage Group and Gao Bei Dian Water Recycling Plant have placed in our ability to provide reliable supply,” said John Panikar, president of Praxair Asia. “Praxair is proud of this opportunity to provide our high-quality products, technology and service to help our customer innovate and to support the municipality’s needs.”
