Synthetic Membrane Processes: Fundamentals and Water Applications presents a summary of some of the theoretical developments in membrane and fluid transport. The book reviews water and wastewater hyperfiltration, ultrafiltration, and electrodialysis, as well as the economics of these processes. The text approaches the topics from the standpoint of chemical engineering. It provides a description of procedures for maintaining reasonable fluxes with a balanced pretreatment, cleaning, and fluid management program. The different structures of water and aqueous systems, hyperfiltration membranes, and the polarization phenomena in membrane processes are also discussed. The text provides concrete examples of the desalting experience and water and wastewater treatment in the United States, Europe, and Japan. The book targets those in the water and wastewater field and is also generally useful for teaching and for anyone interested in adapting membrane technology to separation or concentration applications.
