Gas sparging

Advances in material science promise the development of a new generation of ultrapermeable membranes (UPMs) for reverse osmosis (RO) desalination and water reclamation, which will lead to reduced footprint and lower capital costs. However, due to the attendant increased concentration-polarization (C

Gas sparging and back-flushing treatments were compared as a means to tackle the problem of fouling in yeast microfiltration. Based on the feed and membrane characteristics, it was shown that either of these techniques could be superior to the other in order to overcome the problem. At more concentr

We assessed the potentiality of reducing concentration polarization and enhancing ultrafiltration of macromolecules via gas sparging (gas bubbles supplied to the UF system with the feed solution). Consideration was given to the problem of how the quantity of the gas sparged and the duration of the p
