Advances In Dye Removal Technologies

This book describes the various advanced treatment methods for removal of multiple types of dyes from effluent stream. It pays particular attention to the economic aspects of treatment of textile waste-water. The different technologies illustrated in the book include adsorption, nanofiltration, advanced oxidation, micellar enhanced ultrafiltration, cloud-point extraction, and electrocoagulation. The book presents in-depth analyses of the removal mechanisms and performance optimization of the processes involved therein. This book will be useful to chemists, chemical engineers, environmental engineers, and health and pollution control professionals. The contents have been presented in a manner that they can be easily understood and applied by a wide variety of readers including researchers, students, and practicing engineers.

The book presents a sequential approach for the treatment of dye wastewater, presenting state-of-the-art techniques based on recent findings. The release of these dyes into the environment is a major threat due to their toxicity, mutagenicity and carcinogenicity and their biotransformation products. It has been at least two decades since researchers have been trying to find interactions between dye molecules and water media, and find new purification methods. This book plays an important role in this field by highlighting the cutting edge results in dye removal and remediation, and discusses in detail the application of various physical, chemical, and biological techniques for the removal of pollutants from water.

As society has become increasingly concerned with the protection and preservation of the environment, many industries have been pushed to comply with new policies and social demands for more environmentally-friendly and sustainable practices and products. However, the textile dyeing industry remains a significant source of complex environmental issues with legislative requirements that often vary in detail and severity concerning the exposure and hazards of potentially harmful chemicals and other associated materials. It is vital that the industry sector involved in the application of dyes continues to be sensitive to potential adverse effects on the environment in its widest sense and respond accordingly. Impact of Textile Dyes on Public Health and the Environment is an essential reference source that focuses on the environmental impact and social responsibility of the dyeing industry. While highlighting topics such as toxicology, bleaching, and greenhouse gases, this publication is ideally designed for chemists, industrialists, non-governmental organization members, environmentalists, fashion designers, clothes manufacturers, scientists, academicians, researchers, students, and practitioners seeking current research on dyeing’s potentially adverse effects on the environment and strategic, effective responses.

This series provides information on the nature of dyes, their harmful effects, and dye degrading techniques. The first volume of this series presents a fundamental concept of dye degradation.

Chapters present referenced information and highlight novel breakthroughs in the industry. Key topics: Foundations of Dye Knowledge: Evaluating Toxicity Nanotechnology Electrochemistry Catalytic Materials and Photocatalysis Microbial Biodegradation This book serves as a foundational resource for researchers and students in chemistry and chemical engineering courses. It also serves as a reference for industry professionals who work with chemical dyes (for example in textile and plastic industries) and are engaged in the critical field of environmental remediation. Readership Scholars in chemistry and chemical engineering; professionals in manufacturing industries and environmental sustainability. Series Intro This series provides information on the nature of dyes, their harmful effects, and dye degrading techniques. Each volume will bring a collection of edited topics on dye degradation. The goal of the series is to provide readers with detailed knowledge about dye degradation. The editors also aim to give a broad perspective on the role of dye remediation technologies in creating a sustainable environment.

An enormous amount of synthetic dyes is used annually in the textile, leather, plastics, paper, and dye industries due to their coloring properties. Although dyes give color to materials, they are prone to increase the level of pollution in the environment. The colored wastewater produced in industrial sectors is released into water bodies, posing threats to the ecosystem. To reduce the adverse effects of dyes in the environment, it is necessary to implement feasible and cost-effective strategies. '"Dye Biodegradation Mechanisms and Techniques - Recent Advances'' provides fundamental principles and pathways of bio-based mechanisms in dye removal. This edition firstly discusses dye classification and pollution, then concentrates on the application of fungi, mesophilic bacteria, microflora, and enzymes in dye degradation. This book also highlights the performance of sequential batch reactor systems, moving bed biofilm reactors, and hybrid bioreactors for dye biodegradation​

This book highlights recent findings of membrane - based dye removal methods along with the application of photocatalytic, nanofiltration and ultrafiltration membrane including membrane – based fibers, metal-organic frameworks, polyethersulfone, ceramic, etc. Among water and wastewater pollutants, dyes have been normally observed and detected in various aquatic solutions, including rivers and lakes. Aesthetic pollution, toxicity, persistent, and carcinogenicity are some of the adverse effects of dyes entering the ecosystem. Although dyes have brought a colourful world, their presence in the environment are responsible for adverse effects on the planet. Diverse physical, chemical and biological methods are available to treat dye contaminated water. This book presents membrane separation technology that has been developed in the past decade to treat different wastewaters, and owning to its effective performance, has garnered the attention of academia and industry alike.

The use of synthetic chemical dyes in various industrialprocesses, including paper and pulp manufacturing, plastics, dyeingof cloth, leather treatment and printing, has increasedconsiderably over the last few years, resulting in the release ofdye-containing industrial effluents into the soil and aquatic ecosystems. The textile industry generates high-pollutingwastewaters and their treatment is a very serious problem due tohigh total dissolved solids (TDS), presence of toxic heavy metals,and the non-biodegradable nature of the dyestuffs in theeffluent. The chapters in this book provide an overview of the problem andits solution from different angles. These problems and solutionsare presented in a genuinely holistic way by world-renownedresearchers. Discussed are various promising techniques to removedyes, including the use of nanotechnology, ultrasound, microwave,catalysts, biosorption, enzymatic treatments, advanced oxidationprocesses, etc., all of which are “green.” Green Chemistry for Dyes Removal from Wastewatercomprehensively discusses: Different types of dyes, their working and methodologies andvarious physical, chemical and biological treatment methodsemployed Application of advanced oxidation processes (AOPs) in dyeremoval whereby highly reactive hydroxyl radicals are generatedchemically, photochemically and/or by radiolytic/ sonolytic means.The potential of ultrasound as an AOP is discussed as well.
