The document introduces the Binh Hung water treatment plant in Ho Chi Minh City, Vietnam. It discusses the large volumes of wastewater generated in the city from domestic, medical, and industrial sources, with the majority untreated. It then describes the Dong Dieu pumping station that transports wastewater to the Binh Hung plant and provides an overview of the plant's design and operations. The plant uses activated sludge technology to treat 141,000 cubic meters of wastewater per day to meet national standards. It is staffed by 50 engineers and technicians and has been operating successfully since 2008.

• WASTE WATER IN HOCHIMINH CITY
• DONG DIEU PUMPING
• BÌNH HƯNG TREATMENT PLANT

3. OVERVIEWS OF WASTE WATER IN HOCHIMINH CITY
• Water consumption per capita: 150 l/day
(source: JICA project for sewage planning in Hanoi)
• Total discharge in Ho Chi Minh city: 876,170 m3/day
• 83 hospitals, 26 medical centres - Discharge: 17,000 – 20,000 m3/day
• Total discharge from industrial zones/parks: 400,000 – 500,000 m3/day
• From Domestic: 300,000 m3/day.
(source: 2009, PCD project for building the wastewater pollution control action plan in Ho Chi Minh city)
• Wide range of wastewater . (Industry, domestic, hospital)
• Seprate and combine waste water system.

4. OVERVIEWS OF WASTE WATER IN HOCHIMINH CITY
• Domestic wastewater treated: less than 10%
• Only 30% of the industrial zones/parks have centralized wastewater
treatment systems.
• Can only treat certain pollutants at certain concentration limits. Eg: pH,
BOD, COD, SS, colority, nutrients. (satisfy column A and B of TCVN
5945:2005)
• Planning a system of 9 wastewater treatment plants (one has already
been in operation, 3 are being prepared for construction).
• Building wastewater treatment systems in large hospitals
• Improving centralized wastewater treatment systems of industrial parks
(equipping automatic monitoring system)
