TRAINING.

Overview

After participating in this course, you will be able to:

• Characterize water and identify water types
• Recognize the types of water contaminants and identify the treatment processes and methods for their removal
• Remove suspended solids and colloids, dissolved and particulate organic matter, metals and contaminating inorganic substances from water by conventional and advanced treatment processes
• Recognize the operation principles of conventional and advanced drinking water treatment systems
• Apply your knowledge to select and design appropriate treatment processes for the production of high-quality drinking water

Description
This course discusses the principles and practices of water treatment for the removal of organic and inorganic contaminants, leading to the production of drinking water. It addresses the types of contaminants in water as well as the operation principles and applications of conventional and advanced drinking water treatment processes.

These processes include coagulation-flocculation, sedimentation and clarification, filtration, precipitation, ion-exchange, adsorption, disinfection and membrane processes. Examples of conventional and modern drinking water treatment plants will be presented.

Who Should Attend
Facility/Utility Engineers, Consulting Engineers, Technicians and Technologists, Municipal Planners, Plant Managers, Plant Operating personnel, and anyone interested in learning about drinking water chemistry and treatment approaches
