Book 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, radioactive materials, etc.) with reasonably high efficiency and throughput. It also details the MEUF process for removal of inorganic (cations, anions, and their mixture) and organic pollutants. The authors explain how the economy of the overall process makes recovery and reuse of surfactants essential, and they address various influencing factors on the increase in throughput and the resulting operating problems. Elaborating on technologies involving precipitation and other methods, they also illustrate additional potential applications for MEUF technology.

Book Description
Complete with bibliographic citations and illustrations, this volume focuses on novel techniques and reviews established methods for surfactant-based separation processes that can be widely applied in industry. Describes new extraction techniques, and introduces micellar-enhanced ultrafiltration and admicellar chromatography, discusses protein extraction using reverse micelles, surfactant-enhanced carbon regeneration, and demonstrates new methods of turning waste streams containing dilute concentrations of valuable materials into product streams and examines such traditional surfactant-based methods as froth flotation and foam fractionation.

Book Description
This timely and important book aims to help achieve a more sustainable textile industry; researchers from both textile and environmental domains will benefit from reading it. Since it is imperative to rehabilitate our damaged environmental ecosystems, there is a pressing demand for more sustainable green processes in the textile and clothing industry. As a consequence, greater emphasis needs to be placed on research into eco-friendly processes particularly suited for this industry. With this goal in mind, all environmental aspects relating to the textile and clothing industry are discussed in this book in four broad areas: Highlights the negative impact on the environment by textile industries; Discusses textiles finishing by natural or eco-friendly means; Promotes natural dyes as environment-friendly alternatives to synthetics; Reviews textile effluents remediation via chemical, physical and bioremediation. Included in the 11 informative chapters are topics covering the correlation between the environment and the processing and utilization of textiles and clothing. The book opens with a discussion on the direct impact that the textile industry has on the environment. The hazardous environmental consequences that synthetic dyes used to color textiles have on the environment are highlighted in the next chapter. Greener alternatives to dyeing are discussed in detail in the next chapters followed by a discussion of eco-friendly ways of finishing textiles. The book concludes with a section of chapters providing solutions to address the environmental hazards associated with the textile industry.

Book Description
Using renewable fuels and materials, drinking clean water and food, and breathing safe air are major issues for a sustainable world. This book reviews biodiesel production from microalgae, a promising energy source that does not compete with food production. Several advanced techniques to clean polluted waters, such as electrochemistry, ferrites photocatalysis and low-cost filtration are presented. Chapters also show various living organisms used as bioindicators of toxic metals. Decreasing ecotoxicity of pesticides using suitable surfactants is reviewed. The last chapter evidences new pollutants in urban soils, halogenated polycyclic aromatic hydrocarbons.
