Abstract
South Korea, categorized as a water-stressed country by OECD, predicts that it will be hard to secure water resources for the future. It is important to predict water demand, save water and choose water reuse as alternative water resources. Water reuse has been regarded recently as an important water industry both domestically and internationally in terms of securing alternative water resources and reducing water pollution.
This study aims to raise awareness of not only water reuse in sewage treatment plants but also water reuse in small and medium-scale private sewage plants. In this research, a proper method for water reuse, an equipment that meets water quality standards defined by law were investigated through experimentation.
Two experimental systems which composed of A2/O process and MBR, and MBR and A/O, were chosen for this study to find a proper way to meet a targeted water quality standards for water reuse. In addition, self-sufficient energy system was adopted for the experimental water reuse system. To do this, the study focuses on generating power by a wind-solar hybrid generation system, selecting a battery with proper capacity, and conducting research on an energy management system that can control the energy supply according to the stable and reliable supply system and the importance of loads.
It was revealed that reclaimed water that produced by the experimental equipments can meets the targeted water quality standards for water reuse. It recommends, however, that an in-depth study should be conducted in order to find a way to remove some nutrients that cause eutrophication.
This study also presents a way to operate energy supply systems independently at environmental facilities located in areas where the existing electric power system is not supplied. In an area where the existing electric power system is supplied, the self-sufficient energy supply system can be connected to the existing electric power system, which is economically-efficient.
In conclusion, this study shows there is a possibility of water reuse utilizing an self-sufficient energy supply system. It is expected that water reuse will contribute to securing alternative water resources for the future and reducing water pollution as well as building a low-carbon sustainable environment.
