Water Supply Operations: Coagulation, Flocculation and Sedimentation

The most common method of removing turbidity from source water during drinking water treatment is a combination of coagulation, flocculation, and sedimentation, followed by filtration.

This DVD explains and demonstrates coagulation, flocculation, and sedimentation processes to treatment operators and students. It defines the three treatment processes, gives a step-by-step guide for what to expect at each stage of treatment, and explains how to optimize each process for maximum effectiveness and minimum cost.

The AWWA Water Supply Operations video series provides a practical and cost-effective method for teaching students and new utility employees about municipal water utility operations.
