SUEZ NWS Wins New Projects to Further Align Industrial Growth with Environment Protection

SUEZ NWS recently signed a number of design, engineering and supply of equipment and technical service contracts worth over RMB 500 million. These contracts include the supply of wastewater treatment equipment and full-process technical services for two chemical parks: Lianyungang of Jiangsu and Yantai of Shandong provinces. They also include the supply of municipal and industrial wastewater treatment equipment and technical services in other provinces like Shaanxi, Sichuan and Inner Mongolia.
Delivering innovative solutions to chemical parks
In Wanhua Yantai Industrial Park, SUEZ NWS provides Wanhua Group1, a Global Top 50 chemical company, with integrated wastewater treatment units and a full-process suite for the tertiary treatment of concentrated wastewater. This is the third joint project between the two companies following successful collaborations in 2017 and 2018. The process is the result of intensive innovation and allows the client to reuse discharged ozone exhaust gas in the aerated biochemical reactor, which enables waste gas recycling and also significantly improves the efficiency of biochemical treatment. The project is expected to cut COD emissions and reduce carbon emissions by 13,000 tonnes and 3,930 tonnes per year respectively, whist reducing operating costs and electricity consumption by 681,895 kWh every year.

At the Lianyungang Petrochemical Industrial Base in Xuwei New District, Lianyungang, SUEZ NWS provides a full-stage water treatment solution, along with equipment and technical services to Shenghong Group2, a Fortune 500 company. The project applies SUEZ’s “embedded WWTP” concept which helps our client’s refining-chemical integration project to meet the most stringent discharge standards for wastewater treatment in public works. The solution turns waste into resources and it is projected to reduce carbon emissions by 8,123 tonnes a year.

Improving the quality of wastewater treatment for a better living environment

Additionally, SUEZ NWS also signed a series of municipal and industrial wastewater treatment contracts that have a combined daily treatment capacity of more than 1 million m3. These projects will significantly improve local water quality and wastewater treatment capacity, while enabling the reuse of water and conserving scarce land resources. Among them, the industrial water treatment facilities can help remove large volumes of suspended solids and harmful elements from wastewater, thus preventing secondary pollution of water bodies.


On 21 August 2020, SUEZ NWS signed the contract on integrated wastewater treatment units and a full-process suite for the tertiary treatment of concentrated wastewater with Wanhua Chemical Group Co., Ltd.
