Self-forming dynamic membrane: a review

This paper presents self-forming dynamic membrane (SFDM) process as a promising alternative to membrane technology. A stable dynamic membrane (DM) is mainly composed of gel layer and cake layer which are responsible for filtration and biodegradation. An understanding of the formation mechanism and impact of operating conditions, support mesh, sludge properties and configuration on the formation, and characteristics of the dynamic membrane is essential to optimize the efficiency and reduce fouling propensity of this technology. The paper thus aims to promote its applicability on wastewater treatment. Review of the influence of mesh support properties, different operating conditions and sludge properties on SFDM performance, and cost comparison between MBR and SFDMBR technologies.
