This book summarizes the advanced sustainable trends in removing toxic pollutants by environmental and biotechnological processes from both industrial wastewater and sewage wastewater. The book also provides an assessment of the potential application of several existing wastewater bioremediation techniques and introduces new cutting-edge technologies. Among other valuable information covered, here are the methods, procedures, materials (especially low-cost materials originating from industrial and agricultural waste), management of wastewater containing toxic pollutants, and valorization possibilities of waste resulting from the removal of toxic pollutants from wastewater.
Tonnes of hazardous waste pollutants released by industries are a challenge worldwide. With the ever-growing population and shrinking landfill areas, managing the disposal of pollutants is a matter of severe concern. Industrial wastewater treatment, recycling, and reuse are serious issues in today’s context, not just to protect the environment from pollution, but also to conserve water resources so that water stress is reduced.This book is designed for engineers, scientists, and other professionals and serves as a good summary of the current state-of-the-art and innovative research challenges to control pollution for coming generations.
