Overview of the Research Project
In Vietnam, rapid economic growth has accelerated urbanization and industrialization, leading to a further increase in water demand. In response, the government has been promoting the development of water supply systems under the Vision 2050 strategy, which aims to meet the water demand of all urban and industrial areas by 2050. The urban water supply coverage rate has steadily improved, reaching 92.8% in 2021 (up from 84% in 2016).
In addition to increasing water quantity, the strategy also emphasizes water quality improvement to ensure safe and sustainable water supply. At the same time, wastewater discharge has increased significantly with rising water use, while sewerage infrastructure remains insufficient. As a result, a large portion of wastewater is discharged into rivers without adequate treatment.
Reportedly, 87% of municipal wastewater, about 30% of industrial wastewater, all agricultural runoff, and approximately 95% of livestock waste are released untreated, contributing to the spread of organic pollutants and heavy metals. If this trend continues, worsening river pollution may exceed the capacity of conventional water treatment processes (coagulation, sedimentation, and sand filtration), thereby threatening safe water supply.
Although advanced treatment methods such as ozonation and biological activated carbon are required to address these pollutants, their high capital and operational costs have limited their adoption. In addition, Vietnam is still in the process of strengthening its research capacity in advanced water treatment, which has led to the request for a SATREPS project aimed at developing cost-effective advanced treatment technologies.
Conventional advanced treatment systems require multiple processing steps and various types of equipment, resulting in high capital and energy costs. Therefore, technological innovation is needed to reduce overall costs by simplifying system configurations and improving energy efficiency, thereby reducing both initial investment and operation and maintenance expenses.
