Jangjin Water Treatment Supports Guangxi Beibu Gulf Water Resources Project with Dosing Equipment

Summary: Jangjin Water Treatment has participated in the R&D and application of the 28-billion-yuan Guangxi Beibu Gulf Water Resources Allocation Project. Centered on the Yujiang River, the project covers 44 tunnels and is under construction in four regions, which will provide stable water supply for key cities in Guangxi and improve the ecological environment after completion. To solve the problem of unstable chemical properties and high turbidity of sewage generated by tunnel excavation, Jangjin’s customized dosing equipment (including dosing tanks, screw pumps, mixers, etc.) is deployed at 6 treatment points, using flocculants and citric acid to purify sewage effectively. The project fully demonstrates Jangjin’s strength in industrial water treatment, which also covers mine and construction site wastewater treatment.

Jangjin Water Treatment is honored to participate in the R&D and application of the Guangxi Beibu Gulf Water Resources Allocation Project, a mega project with a total investment of 28 billion yuan, which is crucial for improving water supply security in Guangxi Zhuang Autonomous Region.
Centered on the Yujiang River, the project covers 6 main lines and 44 tunnels, with Zhaiwei Tunnel as one of the most important ones. It is currently under simultaneous construction in four regions: Hepu, Binyang, Lingshan and Fumian, and will provide stable domestic and industrial water for key cities such as Nanning, Beihai, Qinzhou and Yulin upon completion, while improving agricultural irrigation and aquatic ecological environment.
Tunnel excavation generates a large amount of sewage with unstable chemical properties and high turbidity, which poses a major challenge to the project. Jangjin’s dosing equipment, a professional device used in industrial, municipal and environmental water treatment for precise automatic or semi-automatic chemical dosing, has effectively solved this problem.
Composed of dosing tanks (5-15 tons), screw pumps, mixers, pulse dampers and pressure gauges, the equipment is customized for the project: 20-ton large tanks add flocculants to remove suspended impurities and reduce water turbidity, while 5-ton small tanks add citric acid to adjust the pH value of the water. The sewage from the tunnel is stored in a pretreatment sedimentation tank (raw water tank), then undergoes flocculation precipitation and acid neutralization, mixed evenly by mixers, and finally flows into the clear water tank with significantly improved water quality. A total of 6 treatment points are deployed to ensure efficient sewage purification for the tunnel water conveyance project.
In addition to tunnel sewage treatment, Jangjin Water Treatment also has rich experience in industrial water treatment such as mine wastewater and construction site wastewater. This participation in the mega water resources project fully demonstrates the company’s professional strength in water treatment equipment R&D and application, and we will continue to provide reliable water treatment solutions to support global water ecological protection and water security projects.
