Biosolids Treatment and Management

The aim of this 12hr 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. Case studies and real-life examples are used to illustrate approaches and outcomes.

Issues addressed


  • Biosolids management overview – how liquid processing, technologies and treatment, end use and regulations fit together.
  • Regulatory framework – how to classify biosolids in accordance with state biosolids guidelines, stabilisation requirements, grading and selection of end use
  • End use – types and value of end use, maximising the value of biosolids, agricultural beneficial use, avoiding common problems
  • Dewatering – design and performance, gravity drainage deck, belt presses and centrifuges, solar dryers, thermal dryers
  • Transport, storage and odour
  • Workshop – triple bottom line analysis and regulatory compliance


  • Stabilisation – technologies, performance, selecting technologies suitable for your application, basic design parameters, real life examples, managing common problems
  • Integration with liquid processing stream
  • Emerging issues – changing regulations, emerging contaminants such as PFAS and microplastics,
  • Workshop – community engagement
