摘要: |
|
陶瓷膜分离技术是目前国际上最新型的膜分离技术之一,可应用于生物发酵等工业过程中。通常这样的工业过程中涉及到搅拌都会产生泡沫,但是泡沫的产生对生产有不利影响,需要用到消泡剂消除泡沫。本文旨在研究消泡剂是否对陶瓷膜造成污染,消泡剂对陶瓷膜的污染机理,并寻求解决膜污染的清洗方案。实验结果表明消泡剂在40℃下对陶瓷膜过滤造成了污染,聚醚消泡剂中PPG-4000污染最严重,有机硅消泡剂中道康宁1410污染最严重。使用0.5% D3-Ultra®10碱性清洗剂和0.2% D3-Ultra®75酸性清洗剂对污染后的陶瓷膜进行碱洗酸洗,能使膜通量得到很好的恢复。 |

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. |
