Title : Development the cost-effective water treatment materials to supply for flood, drought and saline intrusion areas in Vietnam
Abstract:
Vietnam is significantly impacted by climate change, leading to flooding, drought, and salinity intrusion, which exacerbate clean water shortages. In rural areas of the Mekong Delta, existing water treatment systems meet only 61% of the clean water demand, resulting in the use of substandard water that severely affects public health. Globally, 2.2 billion people lack access to clean water, underscoring the urgent need for effective solutions. This study introduces a novel, cost-effective water treatment material designed for rural Vietnam, capable of producing water that meets the QCVN 01/2009/BYT standards for drinking and domestic use. Testing on heavily polluted canal water in Ho Chi Minh City demonstrated excellent performance, achieving turbidity of 1 NTU, no odor, SS = 0 mg/L, TDS = 0.07 mg/L, COD = 8.5 mg/L, and no detectable coliform or E. coli. Priced at approximately 4 USD/kg, with 1 kg treating 100 m³ of water, this material offers a promising, scalable solution for industrial production and application in rural Mekong Delta and flood-prone regions of Vietnam.
