Fundamentals of Wastewater Treatment and Process Design

Proper wastewater management is critical for public health and environmental sustainability. Understanding how to design and evaluate treatment systems is a foundational skill for aspiring environmental engineers and utility professionals. This text-based course guides you through the entire lifecycle of wastewater purification, from initial screening to safe disposal. You will build a solid theoretical foundation and learn how to solve the core engineering design calculations that keep these systems running efficiently. What you'll learn: 1. Understand key terminology, classification systems, and foundational concepts of wastewater engineering. 2. Analyze preliminary and primary treatment stages, including screening, grit removal, and sedimentation. 3. Evaluate secondary biological treatments, such as activated sludge processes and trickling filters. 4. Solve practical engineering design problems step-by-step to calculate tank dimensions and flow rates. 5. Explore modern wastewater reclamation, reuse strategies, and sustainable decentralized treatment systems. 6. Master safe disposal methods and environmental compliance standards for treated effluent. The course begins with essential definitions and regulatory frameworks before moving systematically through physical, chemical, and biological treatment phases. Each module pairs clear theoretical explanations with written, step-by-step design problems to reinforce your technical skills. Designed for beginners, engineering students, and environmental enthusiasts, this course requires no prior background in water treatment.
