Design of High Turbidity Raw Water: Technical Analysis of Mekong River Water Treatment Project in Vientiane, Laos
Summary
This article takes the high turbidity raw water of the Mekong River in Vientiane, Laos as the research object. In response to the water quality characteristics of sudden increase in turbidity during the rainy season (up to several thousand NTU), a set of prefabricated integrated water purification processes with a daily treatment capacity of 20000 tons was designed and implemented. The system adopts a four stage combination process of hydraulic circulation clarification tank, grid flocculation, inclined tube sedimentation, and gravity type valve free filter, which has strong resistance to impact loads and can adapt to severe fluctuations in turbidity. By optimizing key technologies such as flocculation structure, inclined tube settling, and automatic backwashing, the effluent turbidity is stably controlled at ≤ 0.5 NTU, which is better than the drinking water standards of the World Health Organization and Laos. This process combines the advantages of high efficiency, energy saving, and modularity, providing a scalable technical solution for drinking water treatment in high turbidity river areas in Southeast Asia.
