As a national high-tech enterprise, Tongjie Environmental Protection holds multiple patents and core technologies in membrane separation, zero-discharge treatment of challenging wastewater, seawater desalination, and resource recovery. Its ODM team comprises seasoned process engineers, structural engineers, and electrical control engineers, capable of addressing complex water quality challenges and transforming advanced technologies into stable, reliable, and user-friendly products.

To meet the diverse needs across different overseas regions, we have developed a range of specialized ODM solutions:
– Tropical/subtropical regions: Integrated water purification systems designed for high-temperature and high-humidity environments.
– Areas with limited electricity: Solar photovoltaic-powered seawater desalination systems;
– High-emission standard regions: Integrated near-zero emission systems with a recovery rate exceeding 90%;
– Emergency relief sector: Containerized mobile water treatment stations.

Tongjie operates a pilot-scale facility and a production workshop with an annual capacity of thousands of units. ODM projects can be smoothly implemented through four phases—small-scale testing, pilot production, small-batch manufacturing, and large-scale production—to minimize R&D risks. We also provide international certification support services including CE, UL, and SABS compliance assistance.
