This paper mentions to an application of new type of small wind turbine to power for a safety drinking water disinfection system. In Vietnam, as well in other emerging and developing countries such as in ASEAN, there are considerable problems to realize a safe drinking water supply in rural, removed and island areas. Such regions are characterized by insufficient infrastructure, e.g. there are often no drinking water connection, no wastewater treatment and an unreliable energy supply. As a main problem in water quality, the available surface water is often polluted with germs and coliforms. For an efficient drinking water treatment or disinfection at present and in the medium-term, the needed equipment and requirements for a comprehensive improvement of water quality are not available (e.g., missing chemicals, financial resources, energy capacities). With regard to germ load problem, there are additional difficulties due to microbial recontamination, as well as biofilm formation during water storage at the given climate conditions. The idea for carrying this study is to develop a Safety Drinking Water Disinfection System for rural areas in Vietnam as such as in ASEAN developing countries where the national electric grids may be lacked. The study will focus to develop two main parts: development an energy-efficient UV treatment technology (e.g. LED-lamp irradiation) as main disinfection step with a small-scale electrolysis cell (using MOX electrodes) and development a small Mixture Axis Wind Turbines (MAWT) for supporting the electric to the UV treatment and MOX electrodes. The MAWT wind turbine will works with both horizontal and vertical axis principles of wind turbines. Research found that the safety drinking water disinfection system that powered by wind energy is very suitable with the life standard condition in rural and removed areas in Vietnam.
