Описание: Municipalities face important water supply challenges. One response has been to render utilities independent from municipal government through alternative service delivery (ASD). For its proponents, ASD provides needed autonomy from municipal government; for its detractors, it is privatization under another name. Using Ontario as a case study, Kathryn Furlong paints a complex picture of both ASD and municipal government. Examining organizational models for water supply and how they are affected by shifting governance and institutional environments, she reveals water management and municipal governance to be deeply interdependent and contends that both must be strengthened to meet contemporary water supply needs.
Описание: In the modern world, industries and factories are rising exponentially. This has led to the mass cultivation of non-biodegradable products, like heavy metals, that have polluted the environment and become a major threat to plant growth, crop yield, and human health. Conventional remediation technologies are expensive and may not remove contaminates effectively. Therefore, it is important to develop economically practical and more effective methods to decontaminate soils. Nano-Phytoremediation Technologies for Groundwater Contaminates: Emerging Research and Opportunities is a collection of innovative research on the methods and applications of the use of plants for remediating metal-contaminated soil and water. While highlighting topics including molecular mechanisms, nutrient interference, and fluoride accumulation, this book is ideally designed for environmental scientists, environmental engineers, agriculturalists, farmers, policymakers, government officials, research scholars, professors, and students studying in the fields of environmental engineering, biotechnology, nano-technology, bioscience, and environmental science.

The exploration of new-family desalination techniques has become increasingly important in recent decades. Capacitive deionization (CDI) has attracted multidisciplinary interest as a promising alternative to the conventional desalination techniques of reverse osmosis and electro-osmosis, due to several attractive features such as low energy consumption, environmental friendliness, and high water utilization efficiency. CDI desalts saline water through storing ions in electrical double layers of porous carbons or by redox reactions with faradic materials.
This is the first book to specialise in CDI and aims to showcase the fundamentals and progressive achievements of the research. Chapters cover the timeline of CDI technologies, the expansion of new-family electrode materials, exploitation of new-concept CDI devices, and applications of CDI in other new areas. In addition, the book provides new insights into future directions for the development of CDI and other emerging nanotechnologies for addressing the energy-water nexus.
Edited by a founder of the field, the book will be of interest to those researching water desalination and purification across chemistry, materials science and environmental science.

The deterioration of water quality and unavailability of drinkable water are pressing challenges worldwide. The removal of toxic organic and inorganic pollutants from water is vital for a clean environment, as a response to water scarcity. Adsorption-based water technologies are among the most widely used because of their high efficiency and low cost, without relying on a complex infrastructure. In recent years, carbon nanomaterials (CNMs), such as graphene and derivatives, carbon nanotubes, carbon nanofibers, nanoporous carbon, fullerenes, graphitic carbon nitride, and nanodiamonds have been extensively exploited as adsorbents due to their extraordinary surface properties, ease of modification, large surface area, controlled structural varieties, high chemical stability, porosity, low density, ease of regeneration, and reusability.
This book provides a thorough overview of the state of the art in carbon nanomaterials as they are used for adsorption applications in water purifications, as well as addressing their toxicological challenges. This volume primarily explores the fundamentals of adsorption, its mechanical aspects, synthesis and properties of CNMs, and adsorption performances of CNMs and their nanocomposites with organic and inorganic materials. Structural engineering and activation processes produce materials with enhanced adsorptive properties and separation efficiencies. Furthermore, the formation of CNMs with 2D and 3D macro-and microstructures and high porosities is a potential approach to improve adsorption performances and extend CNM use at the industrial level. The book also addresses important issues regarding these adsorbents that potentially affect future research and industrial applications of carbon-based nanoadsorbents in water security.

A newcomer to the scene, aerobic granulation is on its way to becoming the hot new technology for high-efficiency wastewater treatment. Thus far, intensive research has been conducted with regard to the understanding of the mechanism of aerobic granulation in sequencing batch reactors (SBR) and its application in treating a wide variety of municipal and industrial wastewater. This basic research has promoted the technology from laboratory-study all the way to the present pilot- and full-scale application. The time is right for a reference that discusses the technology and its application in wastewater purification.
Wastewater Purification: Aerobic Granulation in Sequencing Batch Reactors discusses state-of-the-art research and application of this environmental biotechnology tailored to enhanced wastewater purification. The seventeen chapters provide a systematic and comprehensive understanding of aerobic granulation in SBR by incorporating fundamental principles of aerobic granulation with the basis of process operation under various conditions. The book clearly explains what aerobic granules are and how they form. It elucidates key factors that influence aerobic granulation and addresses common problems encountered and their solutions.
This is the first book-length exploration of aerobic granulation. Other books that cover it are smaller, less comprehensive, less in depth, and less up to date. This book provides first-hand information derived from the authors' research and presents a newly-developed theory for aerobic granulation that offers a deep understanding into the essence of current aerobic granulation technology. Using this book as a platform, the technology can be developed further and quickly applied in the wastewater treatment industry.
