Water Pollution

In the context of climate change and fossil fuel pollution, solar energy appears as a cheap and sustainable fuel for many environmental applications, yet the efficiency of techniques has to be improved. This book reviews recent methods and applications of photocatalysis for the treatment of wastewater containing bacteria, heavy metals, organic pollutants, dyes and tannery effluents. Basics of water pollution, polluted river ecosystems and membranes are also detailed.

Pollution of waters by toxic metals is accelerating worldwide due to industrial and population growth, notably in countries having poor environmental laws, resulting in many diseases such as cancer. Classical remediation techniques are limited. This books reviews new, advanced or improved techniques for metal removal, such as hybrid treatments, nanotechnologies and unconventional adsorbents, e.g. metal-organic frameworks. Contaminants include rare earth elements, arsenic, lead, cadmium, chromium, copper and effluents from the electronic, textile, agricultural and pharmaceutical industries.

Sub-Saharan Africa grapples with many public health issues such as food insecurity, increased prevalence of infectious diseases, limited access to clean water supply, poor nutrition and lack of improved health services for its populace (IMF, 2021). Of all these challenges, the inaccessibility of clean water supply for both the rural and urban populace is the most pressing challenge, which has been exacerbated by extensive pollution and climate change crises. The issue of water access and supply affects both rural and urban populations. At rural areas water is accessed in yard taps and in arid regions through water kiosks managed by private owners. Among the urban poor, water access is compromised by poor supply infrastructure especially among informal settlers and risks such as contamination during the supply chain are imminent
This book therefore seeks to close this knowledge gap by 1) generating a water resources inventory for Sub-Saharan Africa region, 2) exploring the water crises in both its urban and rural settings, 3) understanding the causatives of the crises and 4) suggesting viable solutions to manage the water challenges using named case studies. The aim is to improve understanding on the region’s water problems and advise scholars and policymakers on priority research areas and action plans to better water management for sustainable development.

This book details the experiences gained by the Catalan Water Agency (ACA) in a Mediterranean watershed – the Catalan River Basin District – following the launch of the EU Water Framework Directive (WFD) in the year 2000. Experts in rivers, reservoirs, lakes, wetlands and estuaries present 13 chapters defining tools for water-status assessment specially adapted to Mediterranean conditions.

This book compiles 15 chapters about the synthesis, characterizations, and application of many kinds of magnetic adsorbents for water treatment. It is devoted to the scientific community that works with adsorption technologies for water treatment and remediation. Specifically, for professors and Ph.D. students. It is expected that this book serves as an interesting background for researchers in the field of magnetic adsorbents for water treatment.

This book, the second volume in the series, continues to raise contextual issues and presents perspectives regarding multifaceted challenges in management and governance of water in India. This volume attempts to broad base and expand the dialogue started in the first volume and would touch upon issues that need immediate discussion but have been left unattended like politics and management of groundwater, efficient utilization of water in agriculture (irrigation) and improving water use efficiency and building resilience. As in the first volume, this book presents a set of suggestions and recommendations in each chapter that can help frame policy guidelines in the country.

This book presents a picture of the advances in the research of theoretical and practical frameworks of wastewater problems and solutions. The book deals with a basic concept and principles of modern biological, chemical and technical approaches to remediate various hazardous pollutants from wastewater. The latest empirical research findings in wastewater treatment are comprehensively discussed. Examples of low-cost technologies are also included.
