This edited book explores the most promising and reliable technological developments expected to impact on the next generation of desalination systems. The book includes research studies which takes the reader on a fascinating walk through the multidisciplinary world of membrane science applied to water treatment. Concerning the ultimate technological advancement, the book seeks to investigate how to bridge the gap between the laboratory scale and the applicability to industry.
Urbanization, industrialization, and unethical agricultural practices have considerably negative effects on the environment, flora, fauna, and the health and safety of humanity. Over the last decade, green chemistry research has focused on discovering and utilizing safer, more environmentally friendly processes to synthesize products like organic compounds, inorganic compounds, medicines, proteins, enzymes, and food supplements. These green processes exist in other interdisciplinary fields of science and technology, like chemistry, physics, biology, and biotechnology, Still the majority of processes in these fields use and generate toxic raw materials, resulting in techniques and byproducts ...
Using the original writings of two Egyptian Sufis, Muḥammad Wafāʼ and his son 'Alī, this book shows how the Islamic idea of sainthood developed in the medieval period. Although without a church to canonize its "saints," the Islamic tradition nevertheless debated and developed a variety of ideas concerning miracles, sanctity, saintly intermediaries, and pious role models. In the writings of the Wafāʼs, a complete mystical worldview unfolds, one with a distinct doctrine of sainthood and a novel understanding of the apocalypse. Using almost entirely unedited manuscript sources, author Richard J. A. McGregor shows in detail how Muḥammad and 'Alī Wafāʼ drew on earlier philosophical and gnostic currents to construct their own mystical theories and notes their debt to the Sufi order of the Shadhiliyya, the mystic al-Tirmidhī, and the great Sufi thinker Ibn ʿArabī. Notably, although located firmly within the Sunni tradition, the Wafāʼs felt free to draw on Shi'ite ideas for the construction of their own theory of the final great saint.
This book presents advanced techniques for wastewater treatment and the chapters review the environmental impact of water pollution, the analysis of water quality, and technologies for the preservation of water resources. Also outlined in this volume is the bioremediation of heavy metals, dyes, bisphenols, phthalates, cyanobacteria in contaminated water and wastewater. Another focus of this book is the use of natural remediation techniques such as bacterial biofilms and enzymes.
Waste-Based Zeolite: Synthesis and Environmental Applications focuses on the use of waste-based materials to fabricate zeolite and its subsequent use in environmental applications. It presents recent progress in zeolite synthesis using wastes products such as fly ash, steel slag, biomass waste, water treatment plant sludge, and municipal waste, among others. It discusses the application of waste-based zeolite for environmental applications such as biodiesel production, as well as considering techniques for recovering spent zeolite. Many industries produce substantial quantities of waste material comprising various hazardous constituents that lead to pollution and threaten the environment. Ho...

This book offers lucid treatment of fundamental concepts related to potential applications and prospects of different membranes for wastewater decontamination by removing heavy metals. Divided into four sections, it provides an overview of different sources of water contamination, their impacts on human health and the environment, and compares traditional methods used to nullify these impacts. Further, it covers different mature membrane technologies such as polymeric membranes, poly-ceramic membranes, carbon-based membranes and many more, followed by pertinent case studies. Features: Focuses on the removal of heavy metals using membrane-based technologies Discusses pertinent criteria to select suitable membranes Includes feasibility studies and applications of different mature and emerging membranes Describes heavy metals' occurrence and transport in an aqueous system with an overview of the adverse effects Reviews challenges and opportunities associated with using different membranes This book is aimed at graduate students and researchers in materials science, water engineering and wastewater treatment.
This book is the first to provide a complete overview of Islamic extremism in Kuwait. It traces the development of Islamist fundamentalist groups in Kuwait, both Shiite and Sunni, from the beginning of the twentieth century. It outlines the nature and origins of the many different groups, considers their ideology and organization, shows how their activities are intertwined with the wider economy, society and politics to the extent that they are now a strong part of society, and discusses their armed activities, including terrorist activities. Although focusing on Kuwait, it includes overage of the activities of Islamist groups in other Gulf States. It also discusses the relation between Ruling Families with Islamist political groups, thereby demonstrating that the intertwining of Islamic ideology and armed activities with politics is not a new development in the region.
