In September 2025, China celebrated its 47th National Quality Month. Centered around the theme of "Strengthening Comprehensive Quality Management and Promoting the Construction of a Quality-Driven Nation," Hanqi Environment upheld its long-term business philosophy, insisting on digital-driven end-to-end quality control. We are committed to enhancing high-quality project delivery and providing customers with sustainable, high-value services.

In process design, we rely on our self-developed big data OA platform to achieve continuous optimization and quality improvement of process technologies. By tracking and analyzing project water quality data, we determine the most suitable technical parameters for each project, avoiding oversights and redundancies in process units. This approach not only precisely matches customers' actual water quality characteristics and operational needs but also significantly reduces investment and operational costs, ensuring long-term efficient and stable system performance.

In the supply chain and manufacturing stages, our self-developed platform enables real-time data entry and management of all categories of raw materials and equipment. We have established a fully digitalized traceability mechanism covering supplier, performance evaluation, and quality acceptance. Through systematic data tracking and early warning, potential issues can be identified and mitigated before project execution, significantly improving management efficiency. To date, we have developed digital inspection models for 15 major categories of equipment. Over the past year, data-driven approaches have efficiently facilitated over 100 factory inspections, comprehensively ensuring equipment quality compliance and achieving precision and systematization in the quality inspection process. 

During engineering implementation, project teams use mobile terminals to synchronize construction progress and water quality data in real time, while the Tianjin R&D Center provides online analysis and remote debugging support, significantly enhancing response speed and high-quality delivery. To date, Hanqi Environment has successfully delivered over 130 water treatment projects, serving multiple leading clients in the petrochemical industry. Our business is primarily composed of repeat orders, with a repurchase rate exceeding 30%, reflecting strong customer loyalty and brand reputation.

We not only consolidate the foundation of "quality" but also continuously promote innovation and transformation in quality management methods. By integrating quality management with digital technology, we continue to expand digital application scenarios in quality management, delivering more reliable and valuable chemical wastewater treatment solutions for our customers.
