Water is the most crucial material for human survival, after air. Without water, life would not be possible. It is important to know how much water is available to us and how much water is polluted. We need to monitor pollutants vigorously, both at point and nonpoint sources, using advanced analytical techniques that can monitor ultra-trace amounts of contaminants. Water reclamation is an absolute necessity today because we have contaminated our surface water, andeven groundwater in some cases, to a point that it is not clean enough for drinking or cooking. Most importantly, water must be used judiciously, and equal treatment must be paid to the reclamation and treatment of contaminated water.This book provides information on various global water challenges and solutions. We face many water challenges in terms of availability, quality, and sustainability (Chapter 1). There is an urgent need to find ways to make water more sustainable. To achieve this objective, we will have to address scientific, technical, economic, and social issues.

Provides a comprehensive overview of key methods for treating water tainted by cyanobacteria and cyanotoxins Toxigenic cyanobacteria are one of the main health risks associated with water resources. Consequently, the analysis, control, and removal of cyanobacteria and cyanotoxins from water supplies is a high priority research area. This book presents a comprehensive review of the state-of-the-art research on water treatment methods for the removal of cyanobacteria, taste and odor compounds, and cyanotoxins. Starting with an introduction to the subject, Water Treatment for Purification from Cyanobacteria and Cyanotoxins offers chapters on cyanotoxins and human health, conventional physical-chemical treatment for the removal of cyanobacteria/cyanotoxins, removal of cyanobacteria and cyanotoxins by membrane processes, biological treatment for the destruction of cyanotoxins, and conventional disinfection and/or oxidation processes. Other chapters look at advanced oxidation processes, removal/destruction of taste and odour compounds, transformation products of cyanobacterial metabolites during treatment and integrated drinking water processes. Provides a comprehensive overview of key methods for treating water tainted by cyanobacteria and cyanotoxinsBridges the gap between basic knowledge of cyanobacteria/cyanotoxins and practical management guidelinesIncludes integrated processes case studies and real-life examplesDeveloped within the frame of the European Cooperation in Science and Technology (COST)–funded CYANOCOSTA must-have resource for every water treatment plant, Water Treatment for Purification from Cyanobacteria and Cyanotoxins is a valuable resource for all researchers in water chemistry and engineering, environmental chemistry as well as water companies and authorities, water resource engineers and managers, environmental and public health protection organizations.

Combining the basic concepts of photocatalysis with the synthesis of new catalysts, reactor and reaction engineering, this book provides a comprehensive resource on the topic. The book introduces the fundamental aspects of photocatalysis including the role of surface chemistry and understanding the chemistry of photocatalytic processes before exploring the theory and experimental studies of charge carrier dynamics. Specific chapters then cover new materials for the degradation of organics; water splitting and CO2 reduction; as well as reactor and reaction engineering. Researchers new to this discipline can learn the first principles, whilst experienced researchers can gain further information about aspects in photocatalysis beyond their area of expertise. Together with Photocatalysis: Applications, these volumes provide a complete overview to photocatalysis.

Furthermore, the volume discusses water reuse issues and standards, the status of membrane bioreactors applications, and the treatment of reverse osmosis concentrate for enhancedwater recovery during wastewater treatment. Finally, it presents recent developments in potable water reuse and addresses various important issues in this framework, like the proper protection of public health, reliability and monitoring. This volume is of interest to experts, scientists and practitioners from various fields of research, including analytical and environmental chemistry, toxicology and environmental and sanitary engineering, as well as treatment plant operators and policymakers.

This volume discusses the current challenges related to the reuse of wastewater. It reviews the analytical methodologies for evaluating emerging contaminants and their transformation products, the sensitivity of various bioassays for assessing the biological effects of treated wastewater, and the bioavailability and uptake of organic contaminants during crop irrigation. It describes in detail the physicochemical and microbiological alterations in soil resulting from irrigation with treated urban wastewater, and discusses our current understanding of antibiotic resistance in wastewater treatment plants and in downstream environments. The book also includes an analysis of the effect of wastewater entering drinking water sources and production, and provides updated information on wastewater reuse for irrigation in North Africa. It presents an important integration tool for water recovery, known as water pinch analysis, and finally showcases two other examples of reuse – one in the paper industry and one in landfill management. It is of interest to experts from various fields of research, including analytical and environmental chemistry, toxicology and environmental and sanitary engineering.
