In the chemical wastewater treatment industry, stable operation after project delivery is one of the clients’ top concerns. Many projects encounter issues like equipment failures and water quality fluctuations shortly after handover, directly impacting production. Since its establishment, HANQI Environment has regarded “quality control” as the key to sustained and stable project operation, building around it an actionable and traceable quality assurance system.

At HANQI, we believe quality control must start at the technical source. Before launching a project, we conduct full-process testing of chemical wastewater through our professional laboratory platform to ensure the reliability and suitability of the technical approach. During the design phase, we strictly implement a three-tier review process — “design, check, and audit” — with all drawings and plans cross-verified to eliminate errors from the start.

In procurement and manufacturing, HANQI has established a quality traceability system for key equipment and materials, ensuring every batch is clearly sourced and verifiable. During project delivery, we do not rely solely on the experience of onsite personnel. Instead, we use standardized forms and work documents covering every construction step, assigning quality responsibility to each task and ensuring full process documentation and issue traceability.

We have developed our own project management platform to collect real-time quality data at key stages. If data deviates from standards, the system triggers automatic alerts, enabling our team to intervene immediately and ensuring a solid foundation for long-term stable operation even before handover.

Project delivery is not the end. HANQI maintains a standardized after-sales support process, offering regular follow-ups, water quality assessments, and emergency response services to keep projects under control throughout their operational life.

Over the past 15 years, HANQI has completed more than 130 chemical wastewater treatment projects, serving sectors such as petroleum, petrochemicals, and coal chemical processing. Over 30% of our clients have chosen repeat cooperation or continued partnership — the most genuine recognition of our quality control system. We firmly believe in thorough execution at every stage, implementing practical controls, and building reliable quality management. At HANQI, we strive to be a trusted long-term partner to our clients and a true companion over time.
