This book highlights novel materials for dye-containing wastewater treatment and presents an up-to-date information on dye degradation/adsorption using new promising materials such as nanocomposites. Development of various industrial sectors, including textile, food, paper, leather, rubber, cosmetic and printing has led to generation of wastewater which contain dye molecules as well as other inorganic and organic compounds. Considering serious health hazards and environmental damage associated with dyes in the environment, researchers and professionals have been attempting to find the most effective methods of treatment. Of late, various composites have received wide attention due to their outstanding properties in wastewater treatment, that are presented in this book.

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.

Advanced Functional Materials and Methods for Photodegradation of Toxic Pollutants addresses the potential role of visible active photocatalytic methods for the removal of various emerging and persistent organic pollutants (POPs.) Describing the classification, sources and potential risks of emerging organics in water bodies and the environment, the book covers the different synthesis methods of visible active structured photocatalysts and structure related properties to their applications in photocatalytic processes for the removal of antibiotics, pharma and heavy metal pollutants. This book provides an invaluable reference to academics, researchers and technicians in chemical engineering, chemistry and environmental science. In addition, the mechanistic insights associated with the interaction of advanced functional materials and water pollutants along with the possible reaction pathway occurring during the visible light induced photocatalytic processes together with toxicity are discussed in detail along with the reutilization of catalysts, supporting the inherent reaction conditions performed with natural conditions. Covers the recent progress in nano photocatalytic materials Explores the mechanism of photocatalytic degradation of pollutants Includes the controlled synthesis of nanostructured photocatalysts and their modifications for targeted pollutants

The textile industry is among the most significant polluters of water owing to the existence of various types of pollution streams generated by printing processes and textile dyeing. The book begins by documenting various types of Poly (vinyl alcohol) PVA-derived adsorbents (gels, fibers, films, composite particles), membranes, and photocatalysts in combination with conventional adsorbents, polymers, carbonaceous and metallic materials and their use in elimination of dyes from contaminated water. It follows by discussing different properties of nanocomposite membranes such as hydrogels, xerogels and aerogels used in this purpose. Also, different polymer – based adsorbents such as ceramic adsorbent, clay, hydrogels, starch, cellulose, chitosan, alginates, etc are presented in this book.

In arid and semi-arid regions, where water demand exceeds water availability, water security is becoming a significant concern not only related to water availability but also to rigorous and costly requirements to remove conventional and emerging contaminants from effluents discharging into drinking water sources or as water reuse becomes an alternate water supply for communities in these regions. Water and wastewater treatment demands a great amount of energy and resources, highlighting the need for novel applications of the circular economy concept. Circular Economy Applications for Water Security examines knowledge gaps, avenues of future research, and challenges related to the potential of enhanced underutilized/waste materials as a transition to circular economy applications for ensuring the proper quality of water. This book includes fundamental information and practical examples that helps to better understand the concepts included. The circular economy concept is helpful to incept sustainability in the water treatment processes. Every chapter includes the identification of knowledge gaps, avenues for further research, and challenges that guide readers towards real state-of-the-art analysis. Contributors are experts in their areas and will commit to explaining concepts in a user-friendly way without missing scientific rigor.
