Toxic cyanobacteria (blue green algae) have now been reported in 27 countries and are found on all continents including Antarctica. Drinking water authorities world-wide are faced with the challenge of treating contaminated water or the possibility of a toxic bloom occurring sometime in the future. This tailored collaboration project was to provide the international drinking water industry with information to facilitate the confident application of viable treatment techniques for cyanotoxins. Assessment included toxicity of the ozonated solutions, assessment of the protein phosphate inhibition assay technique and the possibility of seeding an activated carbon filter with select bacteria for removal of microcystin-LR. This report offers valuable guidance to the water supplier to aid in deciding upon the most appropriate treatment options for a range of dissolved blue-green algal toxins.

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 cyanotoxins Bridges the gap between basic knowledge of cyanobacteria/cyanotoxins and practical management guidelines Includes integrated processes case studies and real-life examples Developed within the frame of the European Cooperation in Science and Technology (COST)–funded CYANOCOST A 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.

Harmful algal blooms (HABs) occurring in freshwater, and the associated toxins they produce, are dangerous to animals and humans. Mitigating the increasing presence of HABs presents a major challenge to water managers and drinking water utilities across the world. This book explores the current research on removal of HABs and toxins from drinking water. It provides the necessary tools so that treatment plant operators, engineers, and water managers can understand the vulnerability of drinking water treatment plants to HABs and develop treatment processes to minimize the impact of these contaminants. Although conventional treatment processes can be effective for the removal of HAB cells and some HAB toxins under optimal conditions, the potential exists for significant breakthrough of toxins during normal operation. As a result, there is a recognized need for more advanced techniques. Possible advanced processes for removing HAB toxins include granular activated carbon (GAC), powdered activated carbon (PAC), or oxidative processes. This book reviews both conventional and advanced treatment processes and presents clear and easy-to-understand procedures for the design of systems for optimal cell or toxin removal.

Cyanobacterial toxins are among the hazardous substances most widely found in water. They occur naturally, but concentrations hazardous to human health are usually due to human activity. Therefore, to protect human health, managing lakes, reservoirs and rivers to prevent cyanobacterial blooms is critical. This second edition of Toxic Cyanobacteria in Water presents the current state of knowledge on the occurrence of cyanobacteria and cyanotoxins as well as their impacts on health through water-related exposure pathways, chiefly drinking-water and recreational activity. It provides scientific and technical background information to support hazard identification, assessment and prioritisation of the risks posed by cyanotoxins, and it outlines approaches for their management at each step of the water-use system. It sets out key practical considerations for developing management strategies, implementing efficient measures and designing monitoring programmes. This enables stakeholders to evaluate whether there is a health risk from toxic cyanobacteria and to mitigate it with appropriate measures. This book is intended for those working on toxic cyanobacteria with a specific focus on public health protection. It intends to empower professionals from different disciplines to communicate and cooperate for sustainable management of toxic cyanobacteria, including public health workers, ecologists, academics, and catchment and waterbody managers. Ingrid Chorus headed the department for Drinking-Water and Swimming-Pool Hygiene at the German Environment Agency. Martin Welker is a limnologist and microbiologist, currently with bioMérieux in Lyon, France.

Adsorption by Carbons covers the most significant aspects of adsorption by carbons, attempting to fill the existing gap between the fields of adsorption and carbonaceous materials. Both basic and applied aspects are presented. The first section of the book introduces physical adsorption and carbonaceous materials, and is followed by a section concerning the fundamentals of adsorption by carbons. This leads to development of a series of theoretical concepts that serve as an introduction to the following section in which adsorption is mainly envisaged as a tool to characterize the porous texture and surface chemistry of carbons. Particular attention is paid to some novel nanocarbons, and the electrochemistry of adsorption by carbons is also addressed. Finally, several important technological applications of gas and liquid adsorption by carbons in areas such as environmental protection and energy storage constitute the last section of the book. - The first book to address the interplay between carbonaceous materials and adsorption - Includes important environmental applications, such as the removal of volatile organic compounds from polluted atmospheres - Covers both gas-solid and liquid-solid adsorption
