Workpackages - Liaison Groups

In order to achieve topical coordination within the projects of the cluster, 6 liaison groups (LG) have been formed on priority issues. Regular exchanges and meetings are organised by the liaison group leaders in order to ensure sound cooperation between the projects. Public events will be also programmed to enhance the communication with external experts.

Fouling

Better fundamental understanding of membrane fouling in MBR
Identification of design and optimal operation conditions to reduce fouling
Fouling control through dosing of chemical additives
On-line monitoring of fouling substances or sludge fouling propency

LG-Leader: C. Cabassud (INSA)

Cleaning

Identify optimal mechanical or chemical cleaning conditions depending on module and membrane type
Investigation on membrane alteration and ageing through cleaning
Alternatives cleaning strategies and protocols
