The Big Picture

Understand the importance of Activated Sludge in the wider context of Wastewater Treatment and its contributing benefits to energy-from-waste, climate change and economic impacts in relation to carbon tax.

Course Delivery and Context

This course has been designed for live on-line e-classroom delivery via Zoom, for interactive learning, in order to increase the learner’s awareness in specialist subject matter areas. It is part of the wider training Programme for Water Professionals facilitated by Isle.


Activated Sludge is part of the Secondary Treatment process of Wastewater Treatment and is a biological process using aeration and a biological floc composed of bacteria and protozoa.

Although over 100 years old, the course explores the maturation and various arrangements of Activated Sludge Plants that have emerged in response to stringent environmental and water quality guidelines.

Treatment process are directly compared in terms of the carbon and energy requirements alongside spatial footprints, in aid delegates in choosing the best technology on a site by site basis. The delegates are introduced to biological selectors and indicators which support nutrient removal, and their various advantages and disadvantages.

Troubleshooting and preventing common issues such as bulking and foaming are also explored along with virtual guidance on sampling and testing to ensure smooth operation of an Activated Sludge Plant.
