Water treatment for Vietnam

Ceramic membranes for particle removal were applied in parallel operation with conventional sand filtration for drinking water production in pilot scale for application under rural conditions in Vietnam.

The objective of the project was to develop a treatment concept for drinking water production in the rural region of Dong Van in northern Vietnam. Based on the water shortage in the karst region, river water is pumped over a geodetic 400 m difference in level in the Dong Van region. TZW is developing a process concept for treatment of this river water to produce drinking water. The process concept will be provided to the Vietnamese partners, who will implement the process concept into full scale.

Results from pilot-scale trials are incorporated in the process concept. A pilot plant was installed within a container. The pilot plant consisted of various treatment lines including conventional rapid sand filters with flocculation and two lines with ceramic micro- and ultrafiltration membranes. The remote controlled test container was initially operated in Germany and may be shipped to the project region in Vietnam. At the end of the project the pilot plant could remain in Vietnam and produce drinking water as a point-of-use system for a public building.

This research was conducted in co-operation with the company Hydro-Elektrik GmbH within the joint research project KaWaTechSolutions under coordination by Karlsruhe Institute of Technology (KIT) and subsidies of the German Ministry of Research and Education (BMBF).
