Transcription

1 Seminar on Monitoring Technology of Reclaimed Water Quality Current Situation and Vision of Reclaimed Water in Taiwan Kuang-Chih Chang, Director of Planning Division, Water Resources Agency, MOEA(Taiwan)

2 Outline

3 Challenges to Taiwan's water environment

4 Water resource stress forecast Source: World Resources Institute (2015) 4

5 Precipitation (mm) Extreme Events Increasing Caused by Climate Change Annual precipitation has no-significant change, but Period Intensity decrease 3.01% per 10 years increase 3.16% per 10 years Average Year 5

6 Demand for water will continue to increase in response to economic growth. Population concentration in urban areas, water supply and flood control capability have been challenged. The reservoir facilities are silted and aging, and the ability of flood control and drought resistance needs to be improved. River pollution reduce people s willingness of close to water Extreme climate, sea level rise lead to disaster increase including coastal erosion, drought and flood, landslide Coastal erosion Flood Landslide Drought 6 6

7 Alternative Water Resources

8 Diversified Water Recourses Reservoir Traditional River Diversified Water Recourses Alternative Groundwater Reclaimed Water Seawater Desalination Underflow Water Rain harvest 8

9 Discharge Water Sustainable cycle Important of Water Reclamation Reclaimed water is from wastewater treatment plant and not affected by weather, which means it more stable than traditional water resources. Using Reclaimed water can be seen as buy insurance to reduce water shortage risk. Using water twice to enlarge the utility and improve corporate image. Traditional Water resources Electric power consumption 4~5 kwh/m 3 Alternative Water Resources 1~2 kwh/m 3 Reservoir/River Rainfall Desalination Reclamation 9

14 Innovation Reclamation Technology

15 Innovative technology for water reclamation Intelligent Energy Conservation Membrane Distillation (MD) system, waste heat and solar thermal application Resources recycling Water generation Energy generation Energy conservation supported liquid membrane (SLM) system, recovery of rare metal from waste concentrates Capacitive deionization (CDI) module, low power consumption ICT monitoring control system, Energy consumption by intelligent monitoring Industrial wastewater reclamation Information integration Intelligent management Diverse unification construct industry chain 15

16 Membrane Distillation, MD Energy Saving Membrane distillation (MD) is a thermally driven separative program in which separation is enabled due to phase change. Membrane Solar energy Solar energy 1) Operating on low temperature 2) Operating on low pressure 3) Producing high quality pure water Reclaimed water membrane 16

17 Supported liquid membrane, SLM Metal recycling Using extractant to capture the metal ions in wastewater, and than concentrate and recycle of metal ions with stripping agent. Extractant Stripping agent Target metal Extraction Upper layer Stripping 17

18 (<0.5 kwh/m 3 ) Capacitive deionization, CDI Energy Saving Energy Creating (>80%) 18
