Water filtration for Red River delta community
In early 2018, the Arsenic Contaminated Water Treatment project was implemented at Hong Thai commune in the Phu Xuyen district of the Red River delta in Vietnam.
Researchers from Hanoi University of Science (HUS) and UTS surveyed the water, working with local authorities to identify ways to meet the immediate needs of local people.
Currently, water supply for daily living depends on rainwater, which is scarce in dry seasons. Although planning for clean water supply at the Commune has been completed, no implementation schedule has been established, and clean water is not yet possible in the very near future.
“Local communities are very concerned about the health effects of arsenic-contaminated groundwater and eager to explore technologies and access support that can address immediate needs,” said Mr Vu Duc Vinh, Vice Chairman of the Commune.
A pressing need is clean water for the local kindergarten, which is divided into five sites across the district. Only the central site has a standard groundwater treatment system and so all food for children’s lunches can only be produced at this site, then delivered to the others. Teachers at the other sites have to buy locally-produced bottled water for drinking, which is not guaranteed safe.
Therefore, the UTS-developed purification system is well supported by the teachers and Madame Nhan, Vice Headmaster of the Kindergarten, who has followed the research group during the survey and installation.
“I am looking forward to seeing better quality water used for daily activities at the sites, like washing face towels, cleaning baby utensils, and partly for drinking. Our teachers will be more confident using purified water and be less dependent on bottled water,” she said.
