Short description:

Micellar enhanced ultrafiltration (MEUF) employs surfactant micelles to solubilize inorganic and organic pollutants from the effluent stream with about 90 percent efficiency. Illustrating the theory of surfactants, this book presents state-of-the-art research with a detailed description of various aspects of this technology. It covers the fundamentals, selection of surfactants, capability of pollutant removal efficiency, recovery of surfactants, as well as various flux enhancement techniques and the problems associated with them. The text focuses on wastewater treatment and includes case studies, examples, and applications such as the recovery of precious metals and the use of biosurfactants. It also addresses removal of most toxic and hazardous heavy metals and ions.

Long description:

A response to increasingly stringent regulation of pollution and toxicity levels in industrial waste discharge, Micellar Enhanced Ultrafiltration: Fundamentals & Applications offers the most complete book available on the benefits and use of micellar-enhanced ultrafiltration (MEUF) to achieve continuous removal of organic and inorganic pollutants.



An Unparalleled Book That Addresses Both Academic and Industrial Points of View



Several membrane-based techniques, such as microfiltration, ultrafiltration, nanofiltration, and reverse osmosis, are currently used in a wide range of applications throughout the textile, pulp and paper, sugar, chemical, pharmaceutical, biomedical, biotechnological, and food industries. However, although reverse osmosis is an effective means of removing contaminants, this book explains why MEUF is a better substitute, as it less expensive, less energy-intensive, and more efficient and practical for a wider range of applications.



Topics covered include:







  • Effects of pollution in water and its consequences






  • Various treatment processes and membrane technologies






  • Fundamentals of ultrafiltration






  • Outline of various membrane modules and modeling approaches






  • Principles of colloid chemistry






  • Theories of micelle formation






  • Stability and dynamics of micelles






  • Phenomena of counterion binding






  • Solubilization of organic pollutants






  • Selection criteria for surfactants






  • Various flux enhancement techniques






  • Recovery of precious metals






This book conveys how, with proper selection of surfactant and membrane, MEUF can be used to efficiently remove almost all metal ions (heavy metals, lanthanides, radioa
