Advanced Coagulation and Particle Removal

3.0 Credits


This course is a continuation of Water Treatment 2 where coagulation in general terms was introduced. This course takes an in-depth look at coagulation and particle removal. Topics discussed include the advanced principles of coagulation, emerging technologies, jar testing, and clarification methods and equipment. The course aims to provide operators with information that will improve their ability to assess conditions in the water treatment plant and make decisions to ensure the smooth operation of their treatment process.
