The aim of this course is to provide an overview of both, the theoretical and practical aspects of conventional & advanced water technology for surface water treatment.

Learning objectives

On completion of the short course participants should be able to:

understand the basic principles of coagulation, flocculation and disinfection processes, and select appropriate processes depending on the nature of impurities to be removed and the intended use of the treated water.
comprehend the basic principles of membrane processes and the capabilities/constraints of using membrane processes in water treatment applications, and have practical knowledge on the design and operation of these processes.
select an appropriate membrane process for a specific application, and be able to identify appropriate pre-treatment and post treatment schemes, and cleaning protocols for these processes.

Target group

The module specifically targets professionals in water treatment companies, consulting agencies, ministries and equipment suppliers.

Additional information

Didactics:

The module includes lectures, laboratory sessions, design exercises/workshops, and a visit to a modern water treatment plant. The lectures and workshops include computer presentation, and are of an interactive nature. During the design exercise, a computer aided design of a brackish and seawater reverse osmosis system is made using the program Rodesign 7.4 (Hydranautics), and an overview of other computer programs is given. A visit to the world’s largest integrated membrane plant is also included.

Subjects:

Water Quality of Lakes & Rivers
Coagulation & Flocculation Processes
Chlorination & Advanced Disinfection (Ozone & UV)
Desalination & Membrane Related Technologies
Ion Exchange Technology
Water Softening Technology
