Outline of Final Research Achievements

The purpose of this research is to discuss and propose a new water circulation system using reclaimed wastewater as a water resource in Shenzhen, China. A scenario compared the utilization of the reclaimed wastewater inside the city as the water source with a long distance water conveyance from a river, in terms of the amount of the carbon dioxide emission. The use of the reclaimed wastewater produced by a membrane treatment process has some advantage rather than the water conveyance. Although the use of ozonation with the membrane treatment process required more energy, the process is still a promising one because the additional ozonation is able to enhance the quality of water and the use of reclaimed wastewater is able to provide the stable waste resource in quantity and quality.
