Anaerobic Digestion: Sustainable Biosolids Management

Biosolids management in Australia is now changing, and a wide range of pressures are determining that we reuse the resources in biosolids, while avoiding negative environmental or social impacts. Anaerobic digestion has emerged as one of the leading methods for biosolids conditioning, as it produces a better quality product, has relatively low cost components, and is well established. As a process, it is well understood, and simple. However, much of this knowledge has not been widely taught, and there is still a perception that anaerobic digestion is a difficult process. In this course, we dispel this, as well as other myths, and show that anaerobic digestion is a simple, robust process, that is easy to design, operate, and control for a high quality gas and solid product.

The 12hr course will use spreadsheeting extensively, and participants should bring a laptop computer (with Microsoft Excel installed). Macros should be enabled.

Issues addressed


  • Biosolids – what are they?
  • Guidelines, regulations, quality measures, and the case for beneficial application
  • Introduction to biosolids treatment technologies
  • Anaerobic digestion: background, design and application
  • Enhancing anaerobic systems: use of mechanical and temperature conditioning for better digestion. Economic, technical, and environmental analysis
  • Workshop 1: Spreadsheet based analysis of an AD case-study


  • Troubleshooting: what goes wrong with digesters? What impact does it have on quality measure?
  • Digester chemistry, including mini workshop
  • Overall system design: nutrient, solids, energy and transport management
  • Workshop 2: Spreadsheet based analysis of an integrated system

What do you get

Access to an internationally recognised leading researcher and practitioner in Anaerobic Digestion
