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.

Membrane-Based Hybrid Processes for Wastewater Treatment analyzes and discusses the potential of membrane-based hybrid processes for the treatment of complex industrial wastewater, the recovery of valuable compounds, and water reutilization. In addition, recent and future trends in membrane technology are highlighted. Industrial wastewater contains a large variety of compounds, such as heavy metals, salts and nutrients, which makes its treatment challenging. Thus, the use of conventional water treatment methods is not always effective. Membrane-based hybrid processes have emerged as a promising technology to treat complex industrial wastewater. - Discusses the properties, mechanisms, advantages, limitations and promising solutions of different types of membrane technologies - Addresses the optimization of process parameters - Describes the performance of different membranes - Presents the potential of Nanotechnology to improve the treatment efficiency of wastewater treatment plants (WWTPs) - Covers the application of membrane and membrane-based hybrid treatment technologies for wastewater treatment - Includes forward osmosis, electrodialysis, and diffusion dialysis - Considers hybrid membrane systems expanded to cover zero liquid discharge, salt recovery, and removal of trace contaminants

This Volume 2 contains essential contributions highlighting the use of biotechnology in dye removal. It begins with an overview of activated sludge process for dye removal along with its limitation is carried out and describes the fundamental concepts of dye-containing textile wastewater treatments, particularly microbial and enzymatic approaches, including the most usual textile wastewater treatments and their trends. It discusses the role microbial biofilms play when employed in the integrated treatment system for effective detoxification, degradation and complete mineralization of pollutants in dye waste effluents. It assesses the most recent advances in the biotransformation of synthetic dyes from wastewater, especially anthraquinone-typed dyes. Phycoremediation as an emerging and efficient technology in dye removal, remediation strategies used by microalgae, and the role of fungi in the dye removal are presented.

Among various industries releasing wastewater into the environment, printing, dyeing and textile industries are of great importance as they frequently contain high amounts of colorful compounds having high chemical and biological oxygen demands. Health related effects of colorants are extensively reported; which necessitates the seriousness of dye removal from water and wastewater. The utilization of advanced oxidation processes (AOPs) in dye degradation has gained considerable attention recently due to the release of high energetic radicals as oxidants that are capable of removing dye compounds. This Volume 1 presents versatile applications of AOPs in dye removal. Accordingly, processes such as Ozone-based AOPs, UV irradiation, catalytic AOPs, etc are discussed with the aim of dye removal under different operational parameters. The role of different nanoparticles is also investigated. By presenting the fundamentals of AOPs as well as recent advances, this book is useful for environmental engineers and chemists who are concerned with wastewater pollution and treatment.

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​

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.
