Book Description :

The impending crisis posed by water stress and poor sanitation represents one of greatest human challenges for the 21st century, and membrane technology has emerged as a serious contender to confront the crisis. Yet, whilst there are countless texts on wastewater treatment and on membrane technologies, none address the boron problem and separation processes for boron elimination. Boron Separation Processes fills this gap and provides a unique and single source that highlights the growing and competitive importance of these processes. For the first time, the reader is able to see in one reference work the state-of-the-art research in this rapidly growing field. The book focuses on four main areas: Effect of boron on humans and plants Separation of boron by ion exchange and adsorption processes Separation of boron by membrane processes Simulation and optimization studies for boron separation Provides in one source a state-of-the-art overview of this compelling area Reviews the environmental impact of boron before introducing emerging boron separation processes Includes simulation and optimization studies for boron separation processes Describes boron separation processes applicable to specific sources, such as seawater, geothermal water and wastewater

Book Description :

Availability of and adequate accessibility to freshwater and energy are two key technological and scientific problems of global significance. At the end of the 20th century, the deficit of water for human consumption and economic application forced us to focus on rational use of resources. Increasing the use of renewable energy sources and improving energy efficiency is a challenge for the 21st century. Geothermal energy is heat energy generated and stored in the Earth, accumulated in hydrothermal systems or in dry rocks within the Earth’s crust, in amounts which constitute the energy resources. The sustainable management of geothermal energy resources should be geared towards optimization of energy recovery, but also towards rational management of water resources since geothermal water serves both as energy carrier and also as valuable raw material. Geothermal waters, depending on their hydrogeothermal characteristics, the lithology of the rocks involved, the depth at which the resources occur and the sources of water supply, may be characterized by very diverse physicochemical parameters. This factor largely determines the technology to be used in their exploitation and the way the geothermal water can be used. This book is focused on the effective use of geothermal water and renewable energy for future needs in order to promote modern, sustainable and effective management of water resources. The research field includes crucial new areas of study: • an improvement in the management of freshwater resources through the use of residual geothermal water; • a review of the technologies available in the field of geothermal water treatment for its (re)use for energetic purposes and freshwater production, and • the development of balneotherapy. The book is aimed at professionals, academics and decision makers worldwide, water sector representatives and administrators, business enterprises specializing in renewable energy management and water treatment, working in the areas of geothermal energy usage, water resources, water supply and energy planning. This book has the potential to become a standard text used by educational institutions and research & development establishments involved in the geothermal water management.

Book Description :

The growing concern over environmental pollution in recent decades has placed increasing focus on research into the development of sustainable processes associated with the removal of contaminants in waters. Water is scarcer than three decades ago, and there is still no satisfactory solution for the removal of pollutants. One element that has gained worldwide prominence is boron. Although it is a nutrient needed in small amounts for human and plant metabolism, higher levels are toxic to most plants and are associated with reproductive problems in humans. The World Health Organization (WHO) suggests a maximum concentration in drinking water of 2.4 mg/L, but many countries have not yet adopted this recommendation in their water treatment controls. At present, there is no general method for boron removal; several techniques can be used, such as electrodialysis, precipitation, chemical coagulation and electrocoagulation, complexation/nanofiltration, phytoremediation, ion exchange, reverse osmosis and adsorption with different materials. The selection of a particular treatment technology should be made not only on the basis of its efficiency but also with consideration of the associated environmental and financial costs. Biopolymers are a potential solution that has received little attention in the literature. Biopolymers and their derivatives are diverse and abundant in nature; they exhibit fascinating properties and are increasingly important in many applications thanks to their environmentally-friendly characteristics. A small number of publications report the possibility of using tannin gel (Morisada et al., 2011), cellulose cotton (Liu et al., 2007) or chitosan modified with N-methy-D-glucamine (Sabarudin et al., 2005), sugars (Morisada et al., 2011) and diols (Oishi and Maehata, 2013; Fortuny et al., 2014). Biosorption is an effective, simple and cost-beneficial method for the removal of contaminants from waters. This thesis focuses on the development of a sorption-based separation process, using biopolymers and composites for boron removal. The work has been carried out at the Department of Chemical Engineering of the Universitat Politècnica de Catalunya (UPC) in the framework of two research projects (Ref.: CTQ2008PPQ-00417/PPQ and CTQ2011PPQ-22412/PPQ) and the FPI fellowship (BES 2009-026847) financed by the Spanish Ministry of Science and Innovation (MICINN). This work is a continuation of research that has been underway at the Department of Chemical Engineering (UPC) for many years, on the development of advanced separation processes for the removal of valuable compounds or contaminants from aqueous solutions. It contributes to the state of the art on boron separation technologies (examples of which include the development of new composites based on the encapsulation of metal hydroxides in biopolymers). Alginate and chitosan were effectively used as sorbents for boron recovery in the current research. Immobilization techniques were implemented using the technology described by Guibal et al., 2010; active materials are trapped in situ and distributed throughout the polymer support, creating a more stable adsorbent than those obtained by the traditional impregnation method, in which the active material is released partially from the pores of the polymer support while successive adsorption-desorption cycles are performed. Three composite materials have been synthesized in order to improve the sorption capacity, the selectivity towards boron species, and the mechanical properties of the raw sorbents: calcium alginate/alumina (C15l), which improves the sorption capacity of alginate in neutral medium; chitosan/nickel(II) hydroxide [chiNi(III)] and chitosan/Iron(III) hydroxide [chiFer(III)], which increase the sorption uptake of chitosan and improve the handling of hydroxides in the adsorption process, and are stable enough to be used in aggressive environments such as seawater without affecting sorption uptake.

Book Description :

Mass transfer along with separation processes is an area that is often quite challenging to master, as most volumes currently available complicate the learning by teaching mass transfer linked with heat transfer, rather than focusing on more relevant techniques. With this thoroughly updated second edition, Mass Transfer and Separation Processes: Principles and Applications presents a highly thoughtful and instructive introduction to this sophisticated material by teaching mass transfer and separation processes as unique though related entities. In an ever increasing effort to demystify the subject, with this edition, the author— Avoids more complex separation processes Places a greater emphasis on the art of simplifying assumptions Conveys a greater sense of scale with the inclusion of numerous photos of actual installations Makes the math only as complicated as necessary while reviewing fundamental principles that may have been forgotten The book explores essential principles and reinforces the concepts with classical and contemporary illustrations drawn from the engineering, environmental, and biological sciences. The theories of heat conduction and transfer are utilized not so much to draw analogies but rather to make fruitful use of existing solutions not seen in other texts on the subject. Both an introductory resource and a reference, this important text serves environmental, biomedical, and engineering professionals, as well as anyone wishing to gain a grasp on this subject and its increasing relevance across a number of fields. It fills a void in traditional chemical engineering literature by providing access to the principles and working practices that allow mass transfer theory to be applied to separation processes.
