Ms Tang’s research focused on improving cleaning strategies for removing biofilms from membranes used in the dairy industry. Biofilms on membranes result in membrane blockage and probable contamination of the final products. The species in the biofilm and their characteristics were investigated. The most significant contribution was to develop sanitising methods capable of removing almost all culturable cells from the biofilms formed on membranes. This removal will help extend the operating time of the dairy membrane plants, reducing production costs. Appropriate cleaning methods may also extend the operating life of the membrane modules.
