About this course
Course Snapshot
This course is aimed at people responsible for AS/BNR systems operation, assessment, control and optimisation. Completion of the course will provide participants with a working knowledge of the process and how to best optimise their system. The course is unique in that it provides fundamental knowledge of the interaction between biochemical, microbiological and engineering design aspects of the process.
TEXT TO BE ADDED
This course is relevant to you if you are:
- Involved with the management or operation of an activated sludge or BNR plant
- Upgrading your AS plant to BNR
- A scientist working in a laboratory analysing wastewater or researching the AS/BNR process
- Studying environmental engineering or wastewater subjects
- Completing your Certificate III or IV in water operations

Associate Professor Helen Stratton: Course Creator, Lead Facilitator
Helen is a microbiologist with over 27 years-experience in activated sludge microbiology. After completing a PhD studying the microbiology of foaming bacteria in activated sludge she has continued to research biological systems and has published over 90 refereed articles, book chapters and research reports. With this knowledge and experience Helen has continued to be called on to investigate and troubleshoot microbiological problems encountered in biological wastewater treatment processes. She is an Associate Professor at Griffith University and has over 30 years-experience in course design, management and teaching to undergraduates, post graduates and industry personnel.
Peter Griffiths: pH Water Consultant
Over a career expanding more than 40 years, Peter has gained an extensive and somewhat unique understanding of the microbiology and biochemistry of wastewater treatment systems. Coupled with his chemical engineering process skills and his extensive construction, commissioning and operations experience, he continues to develop and improve wastewater treatment technology, particularly biological phosphorus and nitrogen removal to provide reliable and sustainable treatment facilities that are simple to operate and maintain. Peter has been instrumental in the design and delivery of this course and has been training operators, engineers and scientists for over 30 years.
Melody Christie: Course Support Officer
Melody has worked as a research assistant in the water microbiology laboratory, Griffith University for nearly two decades. She is our filament ID guru, undertaking microbiological assessment of wastewater including examination of wet mounts, staining techniques, identification of filamentous and phosphorous accumulating bacteria and compilation of reports. Her expertise in activated sludge microbiology has been an essential in the successful commissioning and optimisation of several activated sludge plants. Mel is currently leading our team in building expertise in molecular techniques for community analysis and targeted analysis for understanding the structure and function of activated sludge microbial communities.
