The commercial operation of atmospheric water harvesting systems is still limited to few countries; this is mainly due to the low energy efficiency of the system and the inability to effectively operate throughout the various seasons of the year. Researchers have attempted to develop strategies to render the operation of atmospheric water harvesters easier and cost effective. This book covers work progress toward such direction, including among others the co-operation of these systems with renewable energy source and the adaptation of the systems to local conditions; the response of the communities around the world to such technology and how its implementation is affected by cultural believe, cost, and technological friendliness. The book is of interest to academic researchers, students, water authorities, professional in relevant industries, government regulatory bodies officers, and environmentalists.

The book elaborates on various physicochemical properties of minerals and technological developments to improve the recovery of metals while ensuring cost-effectiveness and minimal environmental impact. The mineral industry is undergoing significant cultural, organizational, and technological transformations to address some of the major limitations and challenges related to the environmental and productivity domains. As far as productivity is concerned, the decrease of high-grade ores has been one of the stumbling blocks toward the achievement of maximum recovery of metals while, on the other hand, the complexity of minerals therein makes it difficult to profitably extract metals using only conventional methods. This book presents eight specialized chapters that focus on the exploration of the complexity of minerals that are likely to negatively influence the recovery of values, as well as the development of adequate technologies capable of improving the process of mineral concentration and/or metal recovery from complex minerals in a sustainable manner. It reviews the various physicochemical properties of minerals that are likely to pose a challenge during the attempt to recover values using conventional methods. It also elaborates on the recent technological development that has been considered by researchers to improve the recovery of metals from gangue-dominated minerals while ensuring cost-effectiveness and minimal adverse environmental impact. Audience This book will be of interest to academic researchers from the fields of mineral processing, hydrometallurgy, geochemistry, environment, chemistry, engineering, and professionals including mining plant operators, environmental managers in the industries, government regulatory bodies officers, and environmentalists.

The main goal of this book is to review the principles, development, and performances of hybridized technologies that have been used for the treatment of mine effluents. Recent developments consist of the integration/hybridization of technologies to achieve the effective removal of pollutants from acid mine drainage (AMD) effluents in a stepwise manner such as to ensure that the cost of the process is minimized, and the resulting water is fit for purpose. This book presents eight specialized chapters that provide a state-of-the-art review of the different hybridized technologies that have been developed over the years for the treatment of mine effluent, including AMD. The successful implementation and challenges of these technologies are highlighted to give the reader a perspective on the management of such waste in the mining industry. In this innovative book, readers will be introduced to The limitations of passive and active treatment processes as stand-alone technologies while appraising the functioning and performances of these technologies when combined to address their challenges; The numerous approaches that have been considered over the years for effective combination of these technologies are explored taking into account their successful implementation at large scale as well as the long-term sustainability. Audience This book will be of interest to academic researchers from the fields of environment, chemistry, engineering, mineral processing, hydrometallurgy, geochemistry, and professionals including mining plant operators, environmental managers in the industries, water treatment plants managers and operators, water authorities, government regulatory bodies officers and environmentalists.

PHOTOREACTORS IN ADVANCED OXIDATION PROCESSESUnique book covering topics related to the evolving photoreactors concepts, design, and application as well as green synthesis of heterogenous photocatalysts which are the key aspects to facilitate the escalation of bench scale works toward industrial/commercial applications.In this book, the editors present the most up-to-date research on Advanced Oxidation Processes (AOPs) to make the argument that AOPs offer an eco-friendly method of wastewater treatment. In addition to an overview of the fundamentals and applications, it provides ample details of the reactive species involved in AOPs as well as reactor design concepts, thus providing readers with the necessary tools to better understand and implement these methods. Moreover, this book presents some conventional and novel photoreactors equipped with UV/vis lamps for working under solar radiation for wastewater treatment in a laboratory and on an industrial scale, which is an important focus of the book.Readers will find in this book:* In-depth coverage of the performance of sustainable eco-friendly and low-cost heterogeneous photocatalysts (biogenic photocatalysts);* A state-of-the-art fundamental review of parameters affecting photoreactor designs for the effective performance of reactive species;* Identifies, formulates, and analyzes developed processes and technologies to meet desired environmental protection needs of society and formulates solutions that are technically sound, economically feasible, and socially acceptable.AudienceThis book will be of interest to academic researchers and graduate students from the fields of environment, chemistry, and engineering, and professionals including environmental managers in industry, water treatment plants managers and operators, water authorities, government regulatory bodies, and environmentalists.
