Assessing Wastewater Management In India

This book highlights the institutional, legal, and policy measures to manage water pollution in India, and discusses how effective they have been in improving the overall quality of the country’s surface and groundwater resources. It also reviews the status of wastewater generation, collection and treatment in urban areas to provide insights into the gaps in wastewater treatment. Further, it offers a detailed analysis of the wastewater treatment systems available and examines the human health impacts of water pollution in the country, as well as the future trajectory of investment in wastewater treatment systems and potential sectors for reuse and recycling of wastewater, briefly assessing the market demand for treated wastewater. Lastly, it investigates the factors influencing the environmental sustainability and economic viability of wastewater treatment as well as future areas of research in the field.

This book contains up-to-date information and findings in research on the evaluation, treatment, reusability, and development of wastewater in India. The book covers the assessment for drinking water, including membrane filtration, supervision, and evaluation of wastewater, environmental pollution control, wastewater treatment and recycling, advanced bioremediation techniques and wastewater's impact on India. With this wide range of treatment and technologies of wastewater, this book is a source of invaluable information to guide Indian policy planners and makers to move forward to achieve the Sustainable Development Goal 6.

Microbial technology using live, naturally occurring microorganisms in industrial wastewater treatment, is the most effective and innovative method to degrade environmental pollutants such as heavy metals, radionuclides, xenobiotic compounds, organic waste, and pesticides, or to prevent their contamination of the environment. The technology includes several techniques such as biostimulation, biogeneration, bioaccumulation, and biosorption. This book describes the limitations and challenges associated with some generally accepted bioremediation strategies and evaluates the possible applications of these corrective strategies to eliminate toxic pollutants from the environment. The environmental contamination by both natural and anthropogenic sources is, nowadays, an international concern. To decontaminate soils, sediments, and water polluted by anthropogenic activities, scientists and technologists have developed various technologies over the years; however, not only do we have to pay a high cost for physical and chemical environmental technologies but also they sometimes are not ecological or safe. Therefore, we have realized the necessity to develop viable technologies that use microbes and plants to avoid these issues. This book is designed for engineers, scientists, and other professionals who are seeking introductory and advanced knowledge of the principles of nanotechnology, and those who work or are interested in the environmental microbiology or bioremediation field.

This book presents up-to-date information on the status of water resources in India. It presents an assessment of the surface water and groundwater condition to help stakeholders take the necessary actions to control pollution and make the country’s water resources sustainable. The book addresses various topics, including forest-water interactions for governing water quality at catchment scales, water quality status, rainwater harvesting methods, acid-mine drainage, water pollution, management strategies, drinking water quality, and treatment of industrial wastewater. Given its scope, the book offers a valuable tool for policy planners who wish to improve the current situation and move toward sustainable water resources in India.

More than 1 million hectares of urban land in India could be irrigated for crops if wastewater was made safe for use. Lack of systematic data collection by municipalities makes it difficult to accurately assess the wastewater generation or estimate the total amount of urban area under wastewater irrigation, so the potential of urban and peri-urban farming could be even greater. This study attempted to analyze the current status of wastewater generation, its uses and livelihood benefits especially in agriculture, based on national data and case studies from Ahmedabad, New Delhi, Hyderabad, Kanpur and Kolkata.

Life Cycle Assessment of Wastewater Treatment addresses in detail the required in-depth life cycle assessment of wastewater treatment. This is to meet the special demands placed upon wastewater treatment processes, due to both the limited quantity and often low quality of water supplies. Wastewater management clearly plays a central role in achieving future water security in a world where water stress is expected to increase. Life cycle assessment (LCA) can be used as a tool to evaluate the environmental impacts associated with wastewater treatment and potential improvement options. This unique volume will focus on the analysis of wastewater treatment plants (WWTPs), using a life cycle assessment (LCA) approach. Key Features: Focuses on the analysis of wastewater treatment plants using a life cycle assessment (LCA) approach Discusses unconventional water sources such as recycled wastewater, brackish groundwater and desalinated seawater Explains life cycle assessment in detail, which has become one of the reference methods used to assess the environmental performance of processes over their complete life cycle, from raw material extraction, infrastructure construction and operation to final dismantling Explores a technique (LCA) that is becoming increasingly popular amongst researchers in the water treatment field nowadays because of its holistic approach Based on the real life experiences, the subject of wastewater is presented in simple terms and made accessible to anyone willing to learn and experiment

This book documents the various impacts of urbanization on hydrological systems and water resources. The first half of the book is focused on urbanization and surface waters, starting with the status of hydrological systems in the urban areas, i.e. the catchment characteristics and changes in rainfall dynamics. The most pronounced hydrological problems in cities are changes in runoff due to precipitation. Recently, rain events have been less frequent but more intense, sometimes leading to flash floods. Though the substantial increase in runoff causes floods in the urbanized area, it may be attributed to the reduction of infiltration due to construction of roads. This, in turn, results in groundwater decline and depletion. The second half of the book covers the impact of urbanization on groundwater, which starts with hindered or significantly reduced recharge taking place due to altered urban surfaces. The limited groundwater resources are over-exploited by the urban population, leading to water scarcity and depletion. Groundwater gets polluted due to solid waste dumping sites or by wastewaters discharged by industries. The book will be useful for researchers, educators, municipal/city authorities, government officials, and NGOs.

Sewage management refers to the process of collecting, treating, and disposing of the millions of gallons of wastewater produced daily by households, industries, and commercial establishments. It is vital to treat and dispose of this wastewater appropriately to safeguard public health and the environment. The objective of sewage management is to decrease the number of pollutants in wastewater before it is discharged into water bodies or reused for other purposes. Sewage management is a crucial element of modern society, yet it is frequently disregarded or taken for granted. This book offers a comprehensive overview of the various aspects of sewage management, covering the basics of wastewater treatment and disposal, and the various technologies and processes involved in sewage treatment. Additionally, the book provides case studies of successful sewage management practices from around the world, highlighting best practices and innovative solutions. It is hoped that this e-book will serve as a valuable resource for anyone seeking to better understand this critical aspect of modern society.
