About the course

This course is about rehabilitation of water treatment plants. The course covers three types of treatment plants: conventional, thermal desalination; and membrane desalination. Many of the elements in each type of plant are similar.

Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Obtain and apply knowledge on optimization and rehabilitation of water treatment plants
  • Analyze and understand the workings of each type of treatment plant, and plan for the elements for rehabilitation of each type of plant
