Hazardous waste is a waste with properties that make it dangerous or potentially harmful to human health or the environment. Hazardous waste generally exhibits one or more of these characteristics: ignitability, corrosivity, reactivity or toxicity. The universe of hazardous wastes is large and diverse. Hazardous wastes can be liquids, solids, contained gases, or sludges. They can be the by-products of manufacturing processes or simply discarded commercial products, like cleaning fluids or pesticides. One major type is radioactive waste. This book brings together the latest research in this diverse field.
Among various water and wastewater treatment technologies, the adsorption process is considered better because of lower cost, simple design and easy operation. Activated carbon (a universal adsorbent) is generally used for the removal of diverse types of pollutants from water and wastewater. Research is now being directed towards the modification of carbon surfaces to enhance its adsorption potential towards specific pollutants. However, widespread use of commercial activated carbon is sometimes restricted especially in developing or poor countries due to its higher costs. Attempts are therefore being made to develop inexpensive adsorbents utilizing abundant natural materials, agricultural a...
Wastewater Treatment: Recycling, Management, and Valorization of Industrial Solid Wastes bridges the gap between the theory and applications of wastewater treatments, principles of diffusion, and the mechanism of biological and industrial treatment processes. It presents the practical applications that illustrate the treatment of several types of data, providing an overview of the characterization and treatment of wastewaters, and then examining the different biomaterials and methods for the evaluation of the treatment of biological wastewaters. Further, it considers the various types of industrial wastewater treatment, separation, and characterization of industrial wastewater. The book serves as a valuable resource for practicing engineers and students who are interested in the field of wastewater treatment. Features: Presents the latest technologies in water treatment, including nanomaterials for industrial wastewater Covers different treatments for various industrial wastewaters, including chemical and pharmaceutical waste Includes forward-thinking analysis including conclusions and recommendations for water reuse programs
Traditional institutions in the Khasi-Jaintia society are “living organisms” which have existed for centuries and internally evolved from one phase to another. Despite having come into contact with newer and more modern forms of administration, they continue to exist, backed by local public opinion that has called for their continuity amidst diminishing responsibility and utility. This collection of papers explores the landscapes of traditional institutions that exist in the present Khasi and Jaintia Hills in Meghalaya, India. The chapters blend oral tradition with historical records and available sources from secondary literature. They examine the interplay of power and functions between the constitutional authorities, such as the state government, and the Autonomous District Councils and traditional authorities represented by the traditional institutions.
ÔThis book provides a clear analysis of the multi-level impacts of the existing international law regime related to genetic resources on developing countries. It does so through a cogent exposition of the different areas of the law pertaining to genetic resources that are relevant and impact on people's rights and livelihoods. Its focus on equity is a welcome addition to the literature.Õ Ð Philippe Cullet, University of London, UK ÔCamena GuneratneÕs thought-provoking book critically evaluates the clash between the private property approach to genetic resources embedded in international intellectual property conventions, and the competing values embedded in a variety of other convention...
