Over the past six months, SUEZ has signed a series of equipment supply and technical service contracts for total revenues of approximately €38 million. These new contracts, covering numerous Chinese provinces and cities, provide solutions for municipal and industrial wastewater treatment and sludge disposal. They enable SUEZ to better support its clients in many different sectors and help them optimize their treatment processes, while recycling resources, thus promoting circular economy.
Refractory wastewater treatment for energy and chemical industries
In Huizhou (Guangdong), Suzhou (Jiangsu) and Dalian (Liaoning), SUEZ provides raw water, wastewater and sludge treatment equipment and technical services to the Hengli Group, a Fortune Global 500 company. It also builds activated carbon regeneration projects for concentrated wastewater treatment infrastructure. This second wave of projects brings the total number of contracts between SUEZ and Hengli to 12, since the collaboration began in 2015. By reducing operating costs for treating wastewater, SUEZ helps the Hengli Group to reduce CO2 emissions, in particular by reducing its consumption of fossil fuels. Thanks to the project, located in Suzhou, the treated effluent of wastewater meets the most stringent of discharge standards and hits a recovery rate of 80%.
At the Xuwei Petrochemical Park in Lianyungang, SUEZ provides a complete set of technical solutions for a high-salinity wastewater treatment project, for the Shenghong Group, which is also a Fortune Global 500 company. This wastewater treatment plant, with a daily capacity of 2,400 m³per day, is the third project between SUEZ and Shenghong Group. The project uses two-stage OxyblueTM technology to remove refractory organics from the wastewater to ensure that the effluent meets the park’s most rigorous discharge requirements and that clients can run production operations without worrying about pollution.
Industrial water treatment for the aerospace industry
In Shaanxi province, SUEZ supplies, since February 2021, process equipment and complementary technical services for the water supply project in the Xi’an Aeronautics City. This project will effectively make up for the shortfall in the space base’s water supply system, thus meeting the day-to-day needs of more than 300 local businesses settled in the Aeronautics City and residents. It will also achieve the base’s stated objective of “safe, stable, and high-quality water supply from multiple sources”. With a daily capacity of 50,000 m³ of water served each day to 220,000 inhabitants, the expansion of the project plans to upgrade the total capacity to 400,000 m³ per day.
Sludge disposal and recycling
In Jiangsu province, SUEZ provides two dedicated drying treatment lines with a combined daily treatment capacity of 200 tons for the sludge disposal project in the Yangzhou Economic and Technological Development Zone since the beginning of the year. The wet sludge on site is thermally dried and then mixed with coal for combustion at the power plant. Upon completion of the project by the end of the year, the total daily sludge treatment capacity in Yangzhou will reach 500 tons. This project is expected to save about 12,000 tons of standard coal, generate 33 million kilowatt-hours of electricity from the coal-sludge mixed fuel, reduce CO2 emissions by 32,000 tons and save 15 hectares of land.
This year has been tremendously active for SUEZ in China, where we have won numerous contracts and completed several transactions, including the acquisition of NWS’s minority shares in the SUEZ Group’s joint ventures NWS and Suyu. These new contracts, obtained across various sectors of activity, allow us to support our clients in municipal and industrial wastewater treatment and sludge disposal, thus contributing to the country’s green development. SUEZ is proud to continue developing its activities in China and continues to put its expertise and innovative solutions towards its clients, to build a circular economy.
