In October 2026, Professor Fujioka of Nagasaki University and Mr. Hoa, a research assistant, visited Vietnam and inspected Pilot Unit No. 1 installed at the An Duong Water Treatment Plant in Hai Phong.

The main activity during this visit was the installation of a chemical dosing system to introduce pre-coagulation treatment into the pilot unit. This system upgrade will enable further testing and validation of the pilot unit under enhanced operating conditions.

Through continued testing, the project aims to improve the overall performance and design of the pilot system while collecting valuable operational data to support its further development.
