Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 2012-12-06 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, SIld disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS) * at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dissemination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all con cerned if the printing and distribution of the volumes were handled by an interna and broader dissemination. tional publishing house to assure improved service Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Cor poration of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 30 (thesis year 1985) a total of 12,400 theses titles from 26 Canadian and 186 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this important annual reference work.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: To remove metal ions and/or organic molecules from aqueous solutions is a difficulty commonly encountered in the treatment of contaminated water. Traditional ultrafiltration is usually used to separate the high molecular weight molecules and is ineffective in removing heavy metal ions or organic molecules with small molecular weights. Micellar-enhanced ultrafiltration (MEUF) is an effective technique to remove contaminants that traditional ultrafiltration cannot remove. Micellar-enhanced ultrafiltration makes use of the micellar properties of surfactant solutions to remove dissolved ions and/or organics from aqueous streams. Chemical surfactants have proven effective. However compared to biosurfactants they are toxic and create a secondary problem since part of the surfactant monomers frequently leak through the pores of membrane filters. This study is an attempt to examine the effect of rhamnolipid biosurfactant, JBR 425, on contaminant removal from aqueous solutions. The required quantity of rhamnolipid to remove the copper ions as a heavy metal pollutant and benzene molecules as an organic pollutant separately has been determined for different concentrations of pollutants. This quantity, the molar ratio (MR), was 6.25 to obtain a 100% rejection for the copper ions and 1.33 to obtain the same rejection of benzene molecules. When copper and benzene were mixed, these molar ratios have been either improved as in benzene molar ratio which was decreased from 1.33 to 0.56 or remained the same as in copper molar ratio but in all cases rhamnolipid JBR 425 proved of excellent efficiency in the removal of contaminants and a rejection of 100% has been obtained for copper and benzene either separately or simultaneously which is the objective of this study.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Surfactant micelle-assisted removal of ions and organic solutes from aqueous media by micellar enhanced ultrafiltration (MEUF), which is a membrane separation technique, is discussed in detail. Following general information about micellar structure, counterion binding, substrate solubilization, and medium effect functions of micelles which enable separation of cationic or anionic ions and organic molecules from aqueous media by MEUF are explained in a comprehensive manner. Some of the recent studies on removing pollutants from wastewater effluents of industrial plants by MEUF, and their results have been summarized to inform about the factors affecting the removal efficiency of this technique. Methods for recovery of surfactant and contaminants from retentate or permeate solutions are also given. Selective separation of metal ions of the same charge from multicomponent solutions is another topic of this chapter. In this context, the last part of the chapter provides an overview on every aspects of ligand modified MEUF (LM-MEUF) process. This report comprises a comprehensive review of MEUF and LM-MEUF studies in the literature.
