Abstract: |
The ceramic membrane separation technique is one of the most advanced separation technologies, and it is widely used in biological fermentation and other industrial processes. Such industrial processes usually involve mixing that will produce foam, but the foam have an adverse effect on production. Using antifoam to reduce foam is necessary. The purpose of this article is to study the fouling effect of various antifoams on ceramic membranes, and cleaning of the antifoam contaminated membranes.The results showed that PPG-4000 and Dow Corning 1410 cause the worst contamination. The ceramic membranes were cleaned with 0.5% D3-Ultra® 10 and 0.2% D3-Ultra® 75 specialty chemicals, and flux was restored. |
