Course Overview

Many of the Process Controllers who are involved in wastewater treatment are quite proficient in their understanding of the processes being applied during treatment, but need some assistance when it comes to the calculations required to optimise these processes.  This course focuses on those calculations as they apply to the Secondary Treatment Processes, especially Activated Sludge. The course is intended to be an interactive training event where the calculations will be unpacked, practiced and then interpreted in practical on-site situations.

Who should attend?

  • Process Controllers
  • Superintendents
  • Plant Technicians
  • Plant Managers
  • Water sector professionals
  • Officials involved in the treatment of wastewater treatment

Course Outline

Day 1:

  • F:M –ratio

  • Oxygen Requirements
  • COD:TKN -ratio
  • Sludge Volume Index

Day 2:

  • Clarifier Up flow Velocities
  • Clarifier Solids Loading Rate
  • Secondary Process Troubleshooting
  • Practical Exercises & Open Book Test

There will be an open book examination on Day 2 of the course as well as an assignment to be handed in after the course in order for learners to be awarded respective CPD points.

Course Outcomes

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