Plain Sedimentation and Settling Tank Design for GATE CE

To excel in environmental engineering exams, a deep, conceptual understanding of water treatment unit operations is essential. Plain sedimentation is a cornerstone topic that requires both theoretical clarity and precise mathematical application. This text-only course guides you through the foundational physics of particle settling, tank design equations, and the practical calculations needed for competitive exams. You will learn to approach complex design problems methodically through clear, step-by-step written explanations and solved practice problems. What you'll learn: Understand the fundamental principles of plain sedimentation and its role in water purification; Analyze Type 1 settling (discrete settling) using Stokes' Law and Newton's Law; Calculate settling velocity, detention time, overflow rate, and weir loading rates; Design horizontal flow and vertical flow sedimentation tanks using standard engineering formulas; Apply modern design criteria and safety factors to optimize suspended solids removal; Solve exam-style numerical problems with step-by-step written derivations. The course starts with essential terminology and the physical laws governing particle motion in water. From there, you will progress to the structural and hydraulic design of sedimentation basins, concluding with comprehensive practice problems designed to reinforce your analytical skills. This course is designed for civil engineering students, GATE aspirants, and beginners in environmental engineering. No advanced prior knowledge of water treatment is required, though a basic understanding of fluid mechanics is helpful.
