This is a course about how to set up, analyze and run a wastewater treatment plant, whether it is municipal or industrial. It is complete review and teaches analysis and the use of models where appropriate to help analyze operations.

Course Objectives

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

  • Apply an advanced knowledge on sewage treatment and plant operation
  • Analyze, Operate, and Troubleshoot wastewater treatment plants.
  • Learn theory of operations as well as analysis tools and how and where models will be helpful.
  • Learn to analyze poorly performing wastewater treatment works and make recommendations to correct and improve operations, including maintenance.
  • Learn proper techniques for sludge digestion, alternatives to digestion, and sludge disposal.
