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

Book initiates with introductory material to hemodialysis technology and its historical evolution and later on divulging into the field of biomaterials. With this background, the book discusses selection criteria of a suitable biomaterial for synthesis of haemodialysis membranes along with illustration of a complete indigenous, low cost technology for spinning of haemodialysis fibres. Well illustrated description of instruments used for membrane characterization and biomedical engineering is also provided at suitable junctures to effectively present the concept including worked out examples. Present title can be a good textbook as well as a research material for membrane as well as biomedical engineering curricula and provides coverage for appropriate undergraduate and graduate students interested in hemodialysis membranes.

Advanced Technologies in Wastewater Treatment: Wastewater Treatment in the Leather Industry provides a state-of-the-art overview of conventional and emerging technologies for the treatment of wastewater originating from the leather industry. The book pays special attention to the efficiency of these technologies as well as on environmental control strategies. It focuses specifically on wastewater management and recovery of primary resources in the leather industry providing the latest developments in this field as well as applications of conventional and emerging technologies.The book is an indispensable resource for (post) PhD students, researchers at universities and research centers, as well as for professors in chemical engineering and chemistry at technical universities

Includes the latest developments on the treatment of wastewater from leather industryDescribes emerging technologies for pollution controlStudies the integration of conventional and innovative procedures to decrease waste, energy, and water use

Stevioside is one of the naturally occurring sweeteners, belonging to the diterpene glycoside family, which can be widely applied in food, drinks, medicine and consumer chemicals. It is a good dietary supplement, being non-calorific, thermally stable, non-toxic, with a sugar-like taste profile, and suitable for diabetics, phenylketonuria patients and the obese. It is also non-fermentable, and exhibits anti-carcinogenic, antioxidant and anti-hyperglycemic properties. Stevioside tastes about 300 times sweeter than 0.4% sucrose solution. Thus, it offers a reasonably rare combination of health benefits and taste benefits, making the extraction of stevioside is an area of active research for the food industry as well as academic food scientists.With the rapid increase in the popularity of stevioside as a sugar substitute, particularly with regard to its associated health benefits, there is a need for more efficient and feasible extraction processes for stevioside in the near future. This book offers an in-depth look at perhaps the major “sugar alternative of the future”, up-to-date and in line with the latest global legislation regarding its suitability for consumption and its scope for application.
