Principles of Wastewater Microbiology
This course is available at these future events:
Gold Coast 2010

The aim of this course is to teach the microbiological principles that underpin biological wastewater treatment processes. Learn how carbon, nutrients (N&P) and pathogens are removed in biological wastewater treatment systems. Who is responsible ? How do they do it ? How do we control them ? Who are the troublemakers ? Problems such as bulking and foaming will be discussed, and practical control strategies presented.
This is a practical course, and includes a one-day laboratory experience, where everyone will work with wastewater samples and use a variety of microscopy techniques.
ISSUES ADDRESSED
Day 1 Introduction to Wastewater Microbiology
- What is microbiology and which organisms are microbes ?
- What roles do microorganisms play in wastewater treatment ?
- How do they obtain energy and grow ?
- What is the cell genome and what does it do ?
- Which organisms are found in activated sludge plants ?
- How do we study activated sludge microbiology ?
- Case Studies 1 – Troubleshooting activated sludge problems using microbiology
Day 2 Nutrients, pathogens, bulking & foaming
- The microbiology of nitrogen reduction

- What role do microbes play in P removal ?
- Problems that microbes cause in activated sludge
- Which microbes cause bulking and how are they controlled ?
- Which microbes cause foaming and how are they controlled ?
- Pathogens in wastewater
- What pathogens survive the activated sludge process and do we need to worry ?
- Is recycling possible ?
- Can microbiologists and engineers get it together ?!
- Case Studies 2 - Bulking and foaming problems.
Day 3 In the laboratory
- Introduction – why look down the microscope at your mixed liquor or foam ?
- Video of what to expect when microscopically observing mixed liquor
- Preparation of slides
- How to use the microscope
- Observing wet mounts – which are the protozoa?
- Microscopy of mixed liquors
- Identifying filamentous bacteria and poly-phosphate accumulating bacteria
- Summing up – what did it all mean ? How can I use this information ?
WHAT DO YOU GET ?
- Course notes and CD
- Access to two world-leading wastewater microbiologists and one leading wastewater process designer
- The course will be led by Helen Stratton and Bob Seviour, with Peter Griffiths illustrating how core microbiological understanding can help with process design and operation
- Core microbiological skills and understanding to take back to your workplace, which will enable you to analyse and trouble-shoot your wastewater problem
- One day laboratory experience at Griffith University Gold Coast campus
- Understanding of the organisms that make your wastewater treatment process work
WHO SHOULD ATTEND ?
Engineers, consultants, scientists, operators and managers with an interest to know how their biological wastewater treatment plant works. No prior knowledge of microbiology is assumed.
