On September 26, 2026, Bangtec and the Government of Madagascar signed a partnership agreement at the Iavoloha State Palace. The Ministry of Water, Sanitation and Hygiene signed for the government, represented by Minister Dr. Minosoa Anjaratiana Elia Razafindrianiaina. Dr. Huiyu Zhao, Founder and CEO, signed for Bangtec. Two senior advisers of the Refoundation attended on behalf of the President: Médecin Général de Brigade Marcellin Zafitasondry Ranoelson and Colonel Solofoniaina Thierry Rampanarivo.
The agreement concerns the south of Madagascar, where access to drinking water remains a major difficulty. Its aim is to assess the technical and economic feasibility of converting seawater into drinking water as a lasting solution for the people there. The assessment covers technical, economic, environmental and social aspects, the financing model, and the operation and maintenance of the infrastructure.
“This is not only for the south, but for all of Madagascar,” said Colonel Rampanarivo at the ceremony.
The agreement builds on work that started in February 2026. Zhu Wenjie, president of the Madagascar Nantong Chamber of Commerce, presented Bangtec to the Malagasy authorities. Their first question was about power, not water. Along the coast, villages are small and far apart. The grid is weak, and trained maintenance staff are rare. Conventional seawater desalination needs stable power and skilled operators.
Bangtec formed a dedicated engineering team and adapted its compact desalination system to that constraint. Photovoltaic panels generate the power. Battery storage buffers it and drives the desalination system. Bangtec supplies the membranes and the process. The solar panels and batteries come from suppliers in the Nantong High-Tech Zone, where all key components were matched, assembled and tested. All components are specified for a humid, saline coastal environment.
In July 2026, an official delegation from Madagascar came to Nantong to see the system. Dr. Lu Su, Chief Technology Officer, led the group through production and R&D. At the containerized 1:100 scale demonstration unit, prepared test water was fed in place of seawater. Within minutes, clear product water came out, and delegation members tested it on site with their own portable instruments. Both sides signed a framework agreement and agreed to ship a first demonstration unit to Madagascar in a 40-foot container. Bangtec will send a team of about five engineers for installation, commissioning and the training of local operators.
The September agreement with the Ministry is the next step. During the same trip, the Bangtec team also visited coastal communities of timber and corrugated metal houses on open sand. These are the conditions the system was designed for.
