Corrosion and Odour Management in Sewers

From 12/07/17 to 14/07/17

The aim of this course is firstly to teach the key science and engineering principles under-pinning sewer processes, and secondly to use this knowledge to understand and manage key issues like corrosion, odour and greenhouse gas emissions. 

The course presents; outcomes from a $20 million ARC Linkage Project on odour and corrosion, the SCORe Project; and other essential information and proven technologies for the cost-effective management of sewer odour and corrosion. Both liquid and vapor phase technologies will be covered. The effectiveness and limitations of each technology will be assessed through the use of case studies and fundamental knowledge of the in-sewer biotransformation processes.

This is a practical course, and includes several real case studies of successful sewer management approaches.


Day 1: The drivers and under-pinning science

  • In-sewer physical, chemical and biological processes
