Effluents from textile plants are highly toxic and hard to treat by conventional wastewater treatment plants. Since a couple of years, Vietnam is one of the fastest growing countries. A perceptible part of the growth is arising from the textile and garment industry. Wastewater from textile plants is one of the major sources of environmental problems.

The goal of the joint research project is to create partnerships in research, development and implementation in a major field of wastewater treatment, in which modern materials and methods from nanotechnology for the decontamination of dye-contaminated wastewater will be developed and tailored to the conditions in Vietnam.

A valid concept to treat wastewater from plants of the textile industry will be given. One central point is the destruction of effluent dyes with the aid of the photocatalytic process with titanium dioxide and sunlight or extra irradiation units. The overall scope of the cooperation should be the development of a nano-technology-based concept to be efficiently applied to wastewater treatment in developing countries.
