Treatment of Secondary Effluents Using Fly-Ash Based Microfiltration Membrane
Abstract: Fly-ash based microfiltration membrane is a new kind of low cost ceramic membrane. It was used to treat the secondary effluents. The effects of transmembrane pressure and cross flow velocity on the permeation flux were inves-tigated. The membrane fouling mechanism was analyzed based on the pore blocking model. The product water met the requirements of Miscellaneous Domestic Water Quality Standard. It was found that the membrane fouling originated from cake filtration.
