Master plan on bank filtration for supplying drinking water in Vietnam (AquaViet)

At the heart of TZW’s work is the development and demonstration of a concept to disinfect bank filtrate under difficult boundary conditions at two locations in the Hanoi region: the Cãu River and Red River.

New disinfection methods are used on a pilot scale (electrochlorination, stable chlorine dioxide, UV). The aim of AquaViet is to design and demonstrate a concept to supply drinking water from treated bank filtrate in Vietnam. In particular, researchers should assess the advantages and application limits of bank filtration under difficult boundary conditions: high pollution in terms of turbidity, total organic matter, anthropogenic micropollutants, ammonium, arsenic, iron, manganese, pathogenic microorganisms and flood risk. The project is focused on two locations on the Cãu River and Red River in the Hanoi region and will develop solutions for the design and operation of systems for the catchment and treatment of water. Based on the predicted change in water quality in bank filtration, also evidenced in the project, and the land-based groundwater quality, innovative technologies are adapted and further developed to efficiently and cost-effectively treat the raw water and to include suitable monitoring systems. The focus of TZW’s work is the use of innovative disinfection methods (electrochlorination, stable chlorine dioxide, UV) on a pilot scale.
