Evaluation of different cleaning agents for the removal of membrane biofilms

About this report:
Dairy concentration membranes are prone to biofouling, which leads to their reduced performance and also poses quality and food safety issues. This research looked into inhibiting and controlling biofilms on whey reverse osmosis (RO) membranes.

Conclusions:
The studies conducted so far established the resistance of bacterial isolates in both planktonic and embedded state.

Project Outcomes:
Enzyme β- galactosidase showed promise by degrading the biofilm matrix of Bacillus biofilms to a higher extent. It may be able to replace the enzyme step of the existing protocol for better cleaning efficiency.
