Introduction to Wastewater Analysis and Biological Treatment

Understanding wastewater composition and the natural processes used to clean it is essential for modern environmental management and public health. This course introduces you to the core science behind water quality metrics and the biological systems that safeguard our water resources. By completing this course, you will transition from having no prior background to confidently interpreting water quality reports and explaining how different biological treatment systems function. You will learn to: Understand key wastewater indicators including BOD, COD, pH, and suspended solids; Identify the differences between aerobic, anaerobic, and anoxic biological treatment processes; Explore the mechanics of activated sludge systems and trickling filters; Analyze modern nutrient removal techniques for nitrogen and phosphorus; Evaluate current environmental compliance standards and sustainability practices in water treatment. You will start with foundational definitions and chemical indicators before exploring the design and operation of biological reactors through clear, written explanations and practical scenario-based exercises. This introductory text-only course is designed for environmental students, facility operators, and anyone interested in ecological sustainability, requiring no prior chemistry or engineering background.
