Water treatment infrastructure

Being central to increasingly complex local projects and a powerful tool to boost a region’s attractiveness, sustainable water management deserves to be supported by industry players with recognised expertise and a thorough knowledge of local issues. Treatment Infrastructure, a business line of SUEZ NWS, designs and builds water treatment facilities for both municipal and industrial customers.

Introducing the most advanced water treatment technologies to China

Treatment Infrastructure (formerly “Degrémont”) is the first business unit that SUEZ NWS launched in Mainland China. As early as 1975, it built the first wastewater treatment plant in Liaoyang. Over the last four decades, we have built more than 300 water treatment facilities in Greater China. Nearly a hundred million people in China benefit from the plants we have built.


Based on the parent group's strong technical strengths, we have introduced a number of proprietary technologies to China. These are widely used in all kinds of water, wastewater and sludge treatment facilities in the Country, including: Aquazur®, Densadeg®, Biofor®, CabarzurTM activated carbon filtration, Aquadaf®, ozone technology, OxyBlueTM, Thermylis®, Innodry®2E, and so on. SUEZ’s Degrémont® Water Handbook, developed by the group, is known as the "Bible of Water Treatment", and is a widely used textbook by the environment academics across Chinese universities.
