Sustainable Resource Recovery from Wastewater

Wastewater is no longer just waste to be treated and discarded; it is a vital source of energy, nutrients, and reusable water. Understanding how to extract these valuable resources is essential for modern environmental management and circular economy initiatives. This course guides you through the fundamental principles and practical applications of resource recovery from used water. You will begin by mastering foundational concepts, key terminology, and the environmental science of wastewater composition. From there, you will explore the chemical, biological, and physical processes used to capture energy, reclaim clean water, and extract essential nutrients like phosphorus and nitrogen. The text-only format allows you to focus deeply on the underlying science, engineering calculations, and system designs at your own pace. What you'll learn: - Understand the core principles of circular economy and resource recovery in wastewater management - Analyze the biological and chemical processes used to extract nitrogen and phosphorus - Evaluate modern technologies for energy recovery, including biogas generation and thermal extraction - Design basic water reclamation workflows for industrial and municipal reuse - Apply sustainability metrics to assess the environmental and economic impact of recovery systems - Explore emerging trends in decentralized treatment and smart monitoring systems This course is structured to build your knowledge from the ground up, starting with basic definitions and historical contexts before moving into technical recovery pathways and real-world system designs. You will read detailed explanations, analyze process flows, and complete conceptual exercises to solidify your understanding. This course is designed for beginners, environmental science students, municipal planners, and sustainability advocates who want a solid foundation in modern wastewater engineering. No prior engineering degree is required. Start reading today to help build a circular, water-secure future.
