This is the first of two volumes that together provide a comprehensive overview of the current sustainable and low-cost wastewater treatment technologies applied in communities that lack the financial and technical resources needed for an environmental, disease prevention and health nexus.This book reviews natural wastewater treatment technologies and traces the current challenges in wastewater management and sustainability. Divided into 4 themed parts, the chapters from expert contributors cover topics such as simplified and low-energy natural treatment facilities, bioremediation and biotechnology for green future, environmental impact assessment of wastewater reuse, wastewater management and sustainability for irrigation, high-performance and cost-effective biosorbents for heavy metals removal, and eco-friendly nanomaterials for wastewater environmental management. The readers will discover essential recommendations for improving natural treatment systems to withstand emerging contaminants, namely, endocrine disruption chemicals, surfactants, personal care products, pesticides, and pharmaceuticals. Readers will also find valuable guidelines to ensure sustainable and innovative solutions for wastewater treatment in the light of climate change, resource, demand, and funding challenges.Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.

This is the second of two volumes that together provide a comprehensive overview of the current sustainable and low-cost wastewater treatment technologies applied in communities that lack the financial and technical resources needed for an environmental, disease prevention and health nexus. This book reviews engineered wastewater treatment technologies and discusses their application in regard to greenhouse gas emissions, natural resource utilization, land-use, and energy and water savings. The chapters from expert contributors cover topics such as aerobic and anaerobic biological treatments, chemical treatments and precipitation, and disinfection. Readers will also learn about simplified and low-energy wastewater treatment plants, strategies for wastewater reuse, and nanotechnologies for wastewater environmental management. The feasibility regarding time and cost of implementing such technologies is also discussed in this book, and particular attention is given to the removal of conventional and emerging pollutants, toxicants, and heavy metals. Given the breadth and depth of its coverage, the book offers an invaluable source of information for researchers, students and environmental managers alike.
