Biosolids Treatment and Management

The aim of this course is to teach the fundamentals underpinning biosolids treatment and management.  Learn how to analyse and classify biosolids, how to select and design key treatment technologies, how the biosolids guidelines are used, and how to analyse biosolids operating problems. Biosolids handling is a major component of wastewater treatment operation and often accounts for half the total operating cost of sewage treatment. Optimising biosolids management and properly integrating it with the rest of the plant is frequently the best way to cut costs, reduce the environmental footprint, and at the same time, generate valuable, renewable resources.

This is a practical course, focusing on both management and technology, and several Australian case studies are used to illustrate approaches and outcomes.

Due to the COVID-19 pandemic restrictions the course will be delivered online. There may be some changes to the way it has been traditionally delivered but the key learning objectives remain the same and will still be delivered with the full complement of CPD hours.

Issues addressed


  • Biosolids management overview -how technology, end use, liquid stream and other factors fit together
  • Biosolids end use – current regulatory framework, how to classify biosolids in accordance with the biosolids guidelines, stabilisation requirements, end use storage and application operations
  • Biosolids destruction vs beneficial use
  • Biosolids management – practical examples of treatment and end use problems, impact of upstream operation, integrated assessment of the pre-treatment, stabilisation, and dewatering train
  • Examples of treatment train failures
  • Workshop – The whole biosolids management picture: A case study


  • Design of biological and chemical stabilisation technologies – Anaerobic and aerobic digestion, composting, enhanced treatment, thermal hydrolysis and pyrolysis
  • Dewatering technologies – Design and analysis of dewatering systems such as gravity belts, presses and centrifuges, solar dryers and thermal dryers
  • Integrated system analysis – Impact of upstream properties on stabilisation, dewatering, and eventual disposal options
  • Workshop – Triple bottom line analysis of treatment options in larger systems
  • Emerging issues in biosolids treatment and management including PFAS in biosolids

What do you get

  • Access to two world leading practitioners in biosolids treatment
  • Course notes and USB
