Air Bubbling in Membrane Distillation
- 82 Downloads
Air bubbling is a common method that is used in membrane separation process to alleviate membrane fouling and improve flux. It also is a kind of membrane cleaning method. Till now, gas-liquid two phase flow has been well studied and widely used in microfiltration, ultrafiltration (Cabassud et al. 1997), membrane bioreactor (Psoch and Schiewer 2005), and other traditional membrane separation technologies.
Based on the above advantages of air bubbling, it has been introduced into membrane distillation (MD) process to alleviate membrane fouling and improve the heat and mass transfer efficiency. Researchers have introduced air bubbling into MD process and developed several new kinds of MD process.
