Abstract

© 2021 MPRL. All rights reserved.Membrane bioreactor (MBRs) technology is a crucial treatment process having enhanced solid/liquid separation in the way of biological wastewater treatment. However, clogging problem in MBRs is a critical drawback. Dynamic membrane (DM) technology has recently taking more attention to eliminate the clogging problem. DM is known as a self-forming cake layer on a support layer determining the rejection properties of the system. Recently, there is a great concern and more research need to understand and model the complex structure of DM and find proper support material. This study focused on the development of an efficient DM system with different textile fabric support materials in order to treat domestic wastewater. The applicability of two textile fabrics as cotton textile fabric (TF) and metal braided one (MBTF) as support layers with ultrafiltration membrane (UF) were investigated based on the chemical oxygen demand (COD), suspended solids (SS), specific resistance to filtration (SRF), and cake depth parameters. COD and SS removal efficiencies showed that TF support layer provided better reductions.
