Tailor-made industrial wastewater solutions provided in Zhuhai GaoIan Port driving green development in the Greater Bay Area
China's primary strategy is to establish the Guangdong-Hong-Kong-Macao Greater Bay Area, where 11 cities, with a combined population of 72 million, are clustered. As a core city in the Greater Bay Area, Zhuhai, in Guangdong Province, will have its water environment controlled in line with that of world-class bay areas, thus placing higher demands on environmental companies.
Since 2019, SUEZ and its partner have invested in the construction and operation of industrial wastewater treatment project in Gaolan Port Economic Zone’s petrochemical park, to promote the park's sustainability.
More than 20 Fortune Global 500 companies have settled in the Zhuhai Gaolan Port Economic Zone, along with over 130 industrial companies. Due to these companies’ large-scale production, the Economic Zone’s economy has seen brisk constant growth, becoming a major feature of the province's economic development.
However, the industrial development has also challenged the coastline. Not only does the creation of the Model Zero-Waste Park at Gaolan Port require enterprises to buckle down at the sewage outfall, but it also proposes higher requirements for supporting facilities in the park. SUEZ has tailored and refined our industrial wastewater treatment solutions to preserve marine resources and protect the ecological environment. We help the government to advance an environment protection strategy centred on improving the quality of the ecosystem.
A SUEZ joint venture has built and operated Zhuhai's first centralised industrial wastewater treatment plant, with a daily treatment capacity of 25,000 m3, in the park. The plant's treatment process is precise. Industrial wastewater runs through pipelines to target wastewater treatment plants, to undergo centralised treatment. It’s the first time in Chinese industrial wastewater treatment industry history that SUEZ’s patented PulsagreenTM technology has been deployed in the tertiary treatment phase. This technology ensures a more rigid discharge standard of effluent than what municipal wastewater has.
The centralised wastewater treatment plant has achieved remarkable results. It won an award from the French Chamber of Commerce in China in recognition of its outstanding performance by all sectors of society.
- It has improved the Park’s “soft environment” for investment and helped Zhuhai maximise its contribution to the Greater Bay Area’s development;
- SUEZ has introduced global innovations into Zhuhai to safeguard production safety and support companies in overcoming hurdles like production continuity and stringent environment protection requirements;
- The quality and volume of industrial wastewater from the enterprises are stable. Required infrastructure investment and operating costs are low, forming a wastewater treatment model that is simple to monitor centrally.
