Salinity Gradient Energy and Membrane Filtration: Overview of Principles and Applications

Albert S. Kim, Associate Professor

Civil and Environmental Engineering, University of Hawaii at Manoa, USA

The 21st century can be characterized with two natural scientific issues: climate change and resource depletion.  At a global level, food, energy, and water (FEW) are vital components for life, especially for humans whose bodies are at least 50% water.  Therefore, steady production and availability of water (H2O) is crucial conditions for sustainable growth and development, in addition to energy demand for industrial production.  Technological approaches can help to resolve FEW scarcity while econo-socio-environmental issues such as rapid urbanization, economic transitions, geopolitical problems, or even poverty compound the problem.  Water is abundant in earth, but the majority of it lies in the seas and oceans (96.5%) and polar ice caps (1.7%).  Freshwater is only 0.8% of the entire amount of water on earth with the remaining 1.0% found in slightly salty water (brackish water in estuaries and groundwater in salty aquifers.) With this global distribution of water, over 1 billion people do not have access to clean drinking water and approximately 2.3 billion people (41% of the world population) live in regions with water shortages. Unfortunately, this number is expected to climb to 3.5 billion by 2025. Without doubt, clean water production and its energy requirement must be the most important issues of technological concern. Safe drinking water should be produced by faster, cheaper, and better means of sustainability. In this light, this seminar covers technical topics about global water quality and production from fundamental science to practical applications of membrane filtration processes.
