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.

Book Synopsis Soil and Aquifer Pollution by : Hillel Rubin
Download or read book Soil and Aquifer Pollution written by Hillel Rubin and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Water Research Institute at the Technion (Israel Institute of Technology) is proud to have initiated and sponsored the International Workshop "Soil and Aquifer Pollution: Non-Aqueous Phase Liquids - Contamination and Recla- tion", held May 13th-15th, 1996, on the Technion campus in Haifa. Groundwater contamination is one of the pressing issues facing Israel and other countries which depend on groundwater for water supply. In Israel, 60% of the water supply comes from groundwater, most of it from two large aquifers. The Coastal Aquifer underlies the area where the largest concentration of human activity already takes place, and where much of future development is expected to occur. It is a phreatic sandstone aquifer, vulnerable to pollution from activities at the surface. The Mountain Aquifer is recharged in the higher terrain to the east, and flows, first in a phreatic zone, then confined, westward and underneath the Coastal Aquifer. This limestone aquifer has higher permeabilities and flow velo- ties, so pollution can reach the groundwater quite readily. Smaller local aquifers are also important components in the national water system. While measures are taken to protect these aquifers from pollution, there are locations where contamination has already occurred. Furthermore, accidental pollution may not be totally avoided in the future. Therefore, understanding the processes of groundwater contamination, recommending the proper measures for preventing it, and determining the best means for reclamation once pollution has occurred, are of great practical importance. Non-aqueous phase liquids (NAPLs) are among the most significant contaminants.

This book was released on 1999-03-26 with total page 444 pages. Available in PDF, EPUB and Kindle. Book excerpt: A $19.3 million Department of Defense grant to Rice University funds the Advanced Applied Technology Demonstration Facility (AATDF). One of the project goals is the development of reduction strategies for nonaqueous phase liquids (NAPLs) in the subsurface. Surfactants and Cosolvents for NAPL Remediation records the results of AATDF research. The manual is a guide to the practical application of surfactants/cosolvent for in situ remediation. It is targeted to decision makers and anyone concerned with the design or implementation of these technologies. The book discusses the situational viability of surfactants/cosolvents , the possible results, design, and operation. It includes case studies, step-by-step guidance, and project cost work sheets. The successful results of the AATDF research, as documented Surfactants and Cosolvents for NAPL Remediation, are an invaluable contribution to the future of subsurface remediation. Without source NAPL reduction, the alternative is decades of plume management through pump-and-treat.

Book Synopsis Micellar- and Polymer-enhanced Ultrafiltration for Heavy Metal and Sulfate Removal from Aqueous Solutions by : Weiyun Lin
Download or read book Micellar- and Polymer-enhanced Ultrafiltration for Heavy Metal and Sulfate Removal from Aqueous Solutions written by Weiyun Lin and published by . This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Micellar-enhanced ultrafiltration (MEUF) and polymer-enhanced ultrafiltration (PEUF) show potential as promising techniques to remove dissolved ions from wastewater, but they remain inadequately understood. In this thesis, the MEUF removal of copper, nickel, and cobalt ions from aqueous solutions was investigated. The effect of surfactant-to-metal (S/M) ratio and pH on MEUF performance (i.e., metal rejection rate and permeate flux) were examined to obtain the preferred operational conditions. A resampling-based artificial neural network (ANN) modeling was proposed as a promising tool to predict the MEUF performance and to reveal the importance of process parameters. The model-predicted values showed good agreement with experimental data (R2 > 0.99). S/M ratio and pH had relatively greater contributions to the system performance, whereas sampling time contributed less. A high MEUF efficiency (Rejection > 99%) was achieved. To optimize the system performance and to observe the interactions among operational parameters, the statistical-based response surface methodology (RSM) was used to overcome the drawbacks of the commonly used one-factor-at-a-time method. The thesis is the first study to use an RSM method based on a Box-Behnken design to examine nickel ion removal in a MEUF system while combine with an ANN model. The generated RSM models described the relationship between each performance indicator (nickel rejection rate or permeate flux) and process variables (transmembrane pressure, feed nickel concentration, feed surfactant concentration, and membrane molecular weight cut-off (MWCO) of the membrane). Both RSM and ANN methods adequately described the performance indicators within the examined ranges of the process variables. Next, the thesis targets on sulfate ions, a dissolved anion of increasing concern but not tackled in the MEUF/PEUF field. The thesis is the first study to use MEUF and PEUF to remove sulfate ions as the target component from aqueous solutions. It is also the first to examine the adsorption mechanism of sulfate to surfactant/polymer in such systems. Both MEUF and PEUF were found technically viable to remove sulfate from aqueous streams, with the highest rejection rate (Rejection > 99%) found in dilute sulfate solutions. Further, adsorption equilibrium and kinetics studies show that Freundlich isotherm and pseudo-second-order kinetics can describe the adsorption process. This thesis adds knowledge to the existing MEUF/PEUF techniques by improving system operation, conducting system optimization, and exploring new components (i.e., sulfate ions) that can be removed. It also provides treatment information and potentially facilitates reservoir souring control and mining wastewater treatment.
