Besides other developing and emerging countries, Vietnam is a nation with considerable problems in availability and quality of water. A promising approach of solving this problem consists in treatment of used water and its direct reusing. The so-called grey water can be employed for many purposes, e.g. outside for the irrigation of plants or indoors for the toilet flush or washing laundry. Overall, up to a third of fresh water can be saved like that. Till now, water is not frequently reused because the known technologies do not provide a sufficient quality of grey water or the purification of sewage is simply far too expensive. In the recent years, membrane bioreactor technologies have been established as modern processes in grey water treatment. At present, there are main problems that still have to be overcome:
• Too huge load of water with microorganisms and problematic organic substances
• Too low durability of the expensive membrane by biological fouling
With a simultaneous temporal and spatial MBR and Advanced Oxidation Processes (AOP) treatment these disadvantages shall be overcome. Within the DeGrey project, an efficient technological variant of such a combination will be established considering different water quality parameter such as microbial load, colouring, organic micropollutants and selected sum parameters.
