Introduction to Membrane Technology
Membrane filtration plays an integral role in processing polluted water/wastewater and producing clean water that can potentially be re-used. It is considered a promising method for removing contaminants because of its low treatment time, energy consumption, and higher process capacity. It can be combined with other unit processes sequentially to operate in the continuous mode within an existing water treatment facility. Contaminated drinking water is a major underlying cause of child mortality.
This introductory short-course focuses on the fundamental concepts in membrane technology and its application to wastewater and drinking water treatment. The topics covered will include: membrane process (micro-, ultra-, nano-filtration, and separation; membrane characterization technique (scanning electron microscopy, infra-red thermography, permeability method, thermoporometry); transport in membrane including non-equilibrium thermodynamics; and polarization phenomena and fouling.
• To present membrane process and separation with emphasis on water treatment
• To present methods of membrane characterization
• To understand the concepts of transport phenomena in membrane processes
By the end of the short-course each student should be able to:
• Present fundamental principles of membrane filtration and separation processes
• Understand the concepts of fouling (concentration polarization, pore blockage and cake formation) and cleaning
• Gain basic knowledge on membrane characterization
• Understand applications of microfiltration, ultrafiltration, and nanofiltration membrane processes to water treatment
• Provide hands-on demonstration of membrane technology
• Review case studies, new system designs, economics of membrane systems, pre- and post-treatment technologies
