The effective removal of dyes from aqueous waste is an important issue for many industrialized countries. The traditional treatment methods used to remove dyes from wastewater have certain disadvantages such as incomplete dye removal, high reagent and energy requirements, and the generation of toxic sludge or other waste products that require disposal. The search for alternative and innovative treatment techniques has focused attention on the use of biological materials for dye removal and recovery technologies. This brief summarizes the latest developments in this important field.

Biogas Production covers the most cutting-edge pretreatment processes being used and studied today for the production of biogas. As an increasingly important piece of the "energy pie," biogas and other biofuels are being used more and more around the world in every conceivable area of industry and could be a partial answer to the energy problem and the elimination of global warming. This book will highlight the recent advances in the pretreatment and value addition of lignocellulosic wastes (LCW) with the main focus on domestic and agro-industrial residues. Mechanical, physical, and biological treatment systems are brought into perspective. The main value-added products from lignocellulosic wastes are summarized in a manner that pinpoints the most recent trends and the future directions. Physico-chemical and biological treatment systems seem to be the most favored options while biofuels, biodegradable composites, and biosorbents production paint a bright picture of the current and future bio-based products. Engineered microbes seem to tackle the problem of bioconversion of substrates that are otherwise nonconvertible by conventional wild strains. Although the main challenge facing LCW utilization is the high costs involved in treatment and production processes, some recent affordable processes with promising results have been proposed. Future trends are being directed to nanobiotechnology and genetic engineering for improved processes and products.

In this brief, Mary Virginia Orna details the history of color from the chemical point of view. Beginning with the first recorded uses of color and ending in the development of our modern chemical industry, this rich, yet concise exposition shows us how color pervades every aspect of our lives. Our consciousness, our perceptions, our useful appliances and tools, our playthings, our entertainment, our health, and our diagnostic apparatus – all involve color and are based in no small part on chemistry.

This book addresses a complex issue – water sustainability – that requires a combined approach to manage both water and energy. It highlights several technologies that have been introduced to study the water–energy linkage. It also discusses the need to develop effective laws for water management. In turn, the book assesses hybrid biological systems and demonstrates why they are better for the wastewater treatment process. Lastly, it reviews wastewater quality requirements, which have been the primary driver of industrial wastewater treatment programs in India. Gathering selected, high-quality research papers presented at the IconSWM 2018 conference, the book offers a valuable asset, not only for researchers and academics, but also for industrial practitioners and policymakers.

Municipal and industrial wastewaters contain a wide spectrum of pollutants. Their effective removal presents a challenge for water treatment technology. Biosorption of nutrients and pollutants has been used in sewage treatment since the discovery of the activated sludge process. It is a passive uptake process by which pollutants are adsorbed on the surface of cell walls and/or dissolved in structures of microorganism cells that are present in sludge. Sorbed pollutants remain in the sludge and can be potentially released back into the environment depending on their condition and the reversibility of the pollutant-sludge interaction. An overview of typical biosorption applications for the removal of nutrients, organic pollutants, and metals in wastewater treatment is provided in different areas of their use for the protection of aquatic ecosystems and human health. This book will be of interest to operators of wastewater treatment plants and sludge treatment and disposal facilities as well as to researchers and university students in the field of environmental engineering.
