Ho Chi Minh City to have biggest wastewater facility

Construction of the Nhieu Loc -Thi Nghe wastewater treatment plant project in Ho Chi Minh City, which will be the largest in South-East Asia, is around 41% complete and is expected to be put into use in June of next year.

The project’s investor, the city’s Urban Infrastructure Construction Investment Project Management Board, has recently announced that the project is one of eight component projects of the second phase of the city’s environmental sanitation project worth USD 524M.

The plant will treat wastewater that is currently being discharged untreated into the Sai Gon River.

It uses advanced Moving Bed Biofilm Reactor (MBBR) technology, which is one of the most popular biological treatment methods.

The MBBR wastewater treatment method helps remove organic substances in wastewater.

In this method, the reactor is filled with thousands of biofilm carriers (plastic balls) that protect the bacteria used to break down pollutants in the wastewater.

A diffuser grid produces the air required to effectively disperse the biofilm carriers throughout the basin, while also providing the necessary aeration for biofilm growth.

Once completed, the Nhieu Loc – Thi Nghe wastewater treatment plant can treat 480,000 cubic metres (cu.m) of wastewater per day.
