Sustainable Eco Technologies For Water And Wastewater Treatment

One of the major challenges in the world is to provide clean water and sanitation for all. With 3% fresh water reserves in the earth, there are more than 1 billion people who still lack access to clean drinking water. The declining water quality has not only reduced the life expectancy of humans, but it has also contributed to the deleterious negative impacts on aquatic/marine life, flora, fauna and the ecosystem. However, with rapid technological advancements and the availability of advanced scientific instruments, there has been substantial improvement in the design and operation of water and wastewater treatment systems. Recently, these sustainable eco-technologies have been designed and operated to offer the following advantages: (i) a smaller footprint, (ii) less maintenance, (iii) >99% removal of contaminants, (iv) provides the option for resource recovery, (v) less energy consumption, (vi) minimal use of chemicals, and (vii) less investment and operational costs. This book highlights the technologies used for the removal of pollutants such as dyes, uranium, cyanotoxins, faecal contamination and P/N compounds from water environments, and shows that ecotechnologies are becoming more and more important and playing critical role in removing a wide variety of organic and inorganic pollutants from water. In Focus – a book series that showcases the latest accomplishments in water research. Each book focuses on a specialist area with papers from top experts in the field. It aims to be a vehicle for in-depth understanding and inspire further conversations in the sector.

As we know, rapid industrialization is a serious concern in the context of a healthy environment and public health due to the generation of huge volumes of toxic wastewater. Although various physico-chemical and biological approaches are available for the treatment of this wastewater, many of them are not effective. Now, there a number of emerging ecofriendly, cost-effective approaches utilizing microorganisms (bacterial/fungi/algae), green plants or their enzymes, and constructed wetland treatment systems in the treatment of wastewaters containing pollutants such as endocrine disrupting chemicals, toxic metals, pesticides, dyes, petroleum hydrocarbons and phenolic compounds. This book provides a much-needed, comprehensive overview of the various types of wastewater and their ecotoxicological effects on the environment, humans, animals and plants as well as various emerging and eco-friendly approaches for their treatment. It provides insights into the ecological problems and challenges in the treatment and management of wastewaters generated by various sources.

Sustainable Water and Wastewater Processing covers the 12 most current topics in the field of sustainable water processing, with emphasis given to water as a resource (quality, supply, distribution, and aquifer recharge). Topics covered include emerging sustainable technologies for potable and wastewater treatment, water reuse and recycling, advanced membrane processes, desalination technologies, integrated and hybrid technologies, process modeling, advanced oxidative and catalytic processes, environmentally, economically and socially sustainable technology for water treatment, industrial water treatment, reuse and recovery of materials, and emerging nanotechnology and biotechnology for water processing. Responding to the goals of sustainability requires the maximum utilization of all water resources, water processing with restricted energy costs and reduced greenhouse gas production. Following these trends, this book covers all the important aspects of sustainable water processing and support. Covers cutting-edge topics of water process engineering, sustainability and energy efficiency Fills the transfer knowledge gap between academia and industry by analyzing the associated environmental, economic and sustainability challenges of water processing Includes theoretical and applied research and technological and industrial solutions for sustainable, economic and large scale water treatment, recycling and reutilization Analyzes potentiality and economic feasibility of already commercialized processes

WASTEWATER TREATMENT TECHNOLOGIES Globally, the practice of wastewater treatment before discharge is inconsistent. The United Nations World Water Development Report (2017) estimated that, globally, over 80% of all wastewater is discharged without treatment. The discharge of untreated or inadequately treated wastewater into the environment results in the pollution of surface water, soil and groundwater. According to the WHO, water-related diseases kill around 2.2 million people globally each year, mostly children in developing countries. We need to understand that wastewater is not merely a water management issue – it affects the environment, all living beings, and can have direct impacts on economies. The establishment of UN Sustainable Development Goal 6 (Clean Water and Sanitation), which aims to ensure availability and sustainable management of water and sanitation for all, reflects the increased attention on water and wastewater treatment issues in the global political agenda. Water reuse is one of the most efficient, cost effective and eco-friendly ways to ensure water resilience. Embedding sustainability into wastewater treatment is the best opportunity for industries to drive smarter innovation and efficient wastewater treatment. The modern concept of industrial wastewater treatment is moving away from conventional design. Wastewater treatment technology is moving towards extreme modular design using smart and sustainable technology. This book is intended as a reference book for all wastewater treatment professionals and operational personnel. It may also be used as a textbook on graduate and postgraduate courses in the field of wastewater treatment and management. The book takes a holistic view of the practical problems faced by industry and provides multiple needs-based solutions to tackle wastewater treatment and management issues. It elaborates on selection of technology and their design criteria for different types of wastewater. This will enable engineering students and professionals to expand their horizons in the fields of wastewater treatment and management.
