The spread of an arsenic removal technology using an iron bacteria treatment technique in rural water services in Vietnam

Research grant

Project Description

The objectives of this project are to apply low-cost arsenic removal techniques using an iron bacteria treatment method (that have been studied for many years) to rural water services, confirm the advantages, and with the assistance of Vietnamese government agencies, widely spread these techniques. Mainly in the northern regions of Vietnam where ground water has high concentrations of arsenic, carry out checks of the water quality of existing water services to farming villages and confirm the scope of application of the iron bacteria treatment method. Thereafter, set up a working-scale experimental facility in the water supply of one farming village, train local engineers and gather long-term data on arsenic removal performance while checking various points (economic efficiency) to make the system more practical.
