An energy-efficient method for mitigating membrane fouling : a novel embodiment of the inverse fluidized bed

A novel inverse fluidized bed (IFB) was developed to improve membrane fouling mitigation vis-à-vis the conventional aeration method. The fluidized media, whose density was less than water and oleophilic, were more effective than bubbles for both feeds containing oil and particulates due to their gre...
