Management of Treatment Sludge Impacted by Cyanobacteria
Abstract
The objective of this project was to provide operational guidance for the management of cyanobacterial sludge to ensure compliance with the regulations for cyanotoxins and to safeguard water quality. To achieve this aim, it will be necessary to understand and model the dominant processes occurring in the sludge and supernatant and to apply effective treatment strategies to mitigate risks to water quality. An Executive Summary is posted below. The main deliverables of this project are two peer-reviewed journal articles:
