The textile industry segment has been continuously expanding and it is reported that the global market was US$1000 billion in 2020. Aside from the fact that textile industry could be profitable and offers several advantages for human life, this industry produces wastewater containing many harmful substances in the form of organic and inorganic moieties. Textile wastewater can lead to serious environmental problems if discharged without treatment. In this first volume of the application of biological mechanisms, processes and units are reviewed in terms of dye degradation and removal. The role of biodegradation, bioaccumulation and biosorption in bio-decolorization are discussed. The book starts with highlighting the fundamentals of aerobic and anaerobic mechanisms having different configurations. The moving bed bioreactor (MBBR), up-flow anaerobic sludge blanket reactors, sequential aerobic/anaerobic batch reactors, membrane bioreactor, etc are also covered in this edition.

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.

Textile industry wastewater contains toxic dyes as well as heavy metals and many other persistent organic compounds which are difficult to biodegrade using conventional biological methods. Advanced Oxidation Processes (AOPs) are one of the best alternatives for the effective degradation of such compounds. This Volume 2 starts with homogeneous and heterogeneous Fenton processes and reviews the application and variables that affect the process. It then discusses plasma technology- an emerging method in terms of its chemistry, treatment set-up, limitations, etc. The positive performance of carbon tetrachloride in process intensification of dye degradation is presented. The other chapters include topics such as sonoenzymatic treatment processes, electroflocculation versus textile wastewater, combination of photocatalysis and membrane Separation, and enhancement of anaerobic digestion and photodegradation through adsorption.
