After successfully finishing the dosing system installation at Zhaiwei Tunnel, JUJIN Water Treatment immediately shifted its focus to Lingshan. As another key construction hub of the project, Lingshan plays an irreplaceable core role in the project’s integrated water conveyance network.

At present, the Lingshan Tunnel is under intensive and orderly construction. Tunnel excavation generates a large volume of sewage with unstable chemical properties and high turbidity, which directly affects the construction progress of the project and poses a major challenge to long-term water quality safety. To address this key issue, JUJIN Water Treatment specially dispatched a team of senior professional engineers to the Lingshan site to carry out customized installation and precise commissioning of the dosing system, ensuring that the system can seamlessly adapt to the complex local construction environment and fully meet the project’s stringent water treatment standards.

The installation of a water treatment dosing system in tunnel construction primarily solves the problem of sewage disposal generated by tunnel excavation, ensuring project progress and water quality safety. Tunnel excavation produces sewage with high turbidity, unstable chemical properties and a large amount of suspended solids. The dosing system efficiently removes suspended impurities and reduces turbidity through precise dosing of flocculants, and adjusts the water pH value with acidic reagents, ensuring that the treated sewage meets environmental discharge or recycling standards and avoids polluting the surrounding aquatic ecosystem.

Untreated direct discharge of tunnel sewage may violate environmental regulations and result in construction suspension. The dosing system enables rapid sewage purification, preventing construction delays caused by water quality issues, reducing corrosion of construction equipment by sewage, and lowering equipment maintenance costs. The treated clean water can be recycled for tunnel construction maintenance, dust suppression and other processes, improving water resource utilization, reducing groundwater extraction, and complying with green construction requirements — especially suitable for environmental acceptance standards of large-scale water conservancy and transportation tunnel projects.

The dosing system realizes accurate and automatic reagent dosing. Compared with manual dosing, it not only reduces reagent waste and operation costs but also avoids manual operation errors, ensuring stable and controllable sewage treatment effects.

The dosing system customized for the Lingshan construction site was installed under strict adherence to international and industry technical standards by JUJIN’s engineering team, with full-process construction quality control to guarantee stable, efficient and long-lasting system operation.

As one of the four core construction areas of the Guangxi Beibu Gulf Water Resources Allocation Project, the progress of water treatment in Lingshan is critical to the overall success of the entire project. Upon full completion, the project will completely end the long-term reliance of local residents on well water, providing stable, safe and high-quality domestic and industrial water for Lingshan and wider regions in Guangxi. In addition, the project will greatly improve local agricultural irrigation conditions, support the restoration and improvement of the regional aquatic ecological environment, and inject long-term momentum into the improvement of local residents’ quality of life and regional sustainable development.

JUJIN Water Treatment’s successful completion of the dosing system installation and commissioning in Lingshan fully demonstrates the company’s strong professional capabilities in on-site construction, customized equipment R&D and high-quality technical services. Beyond tunnel sewage treatment, JUJIN Water Treatment has accumulated rich practical experience and mature solutions in various industrial water treatment sectors, including mine wastewater treatment and construction site wastewater treatment.

Moving forward, JUJIN will always adhere to the core principle of “Quality First, Service Supreme”, continuously provide reliable and cost-effective water treatment solutions and professional technical support, and promote the high-quality development of global water resource development and environmental protection undertakings.
