AI Article Synopsis
- The Membrane BioReactor (MBR) is a popular wastewater treatment technology, but it faces issues with membrane fouling, which can hinder performance.
- A new alternative, the Self Forming Dynamic Membrane BioReactor (SFD MBR), employs a biological filter layer that forms on an inert material, potentially reducing costs.
- In lab tests with different nylon mesh sizes and air scouring rates, the SFD MBR demonstrated effective treatment of municipal wastewater, showing better effluent quality with smaller mesh sizes and lower air flow rates.
Article Abstract
The Membrane BioReactor (MBR) is a well-established filtration-based technology for wastewater treatment. Despite the high quality of the effluent produced, one of the main drawbacks of the MBR is membrane fouling. In this context, a possible evolution towards systems having potentially lower installation and operating costs is the Self Forming Dynamic Membrane BioReactor (SFD MBR). Key of this technology is the self-formation of a biological filtering layer on a support of inert material. In this work, a lab-scale aerobic SFD MBR equipped with a nylon mesh was operated at approximately 95Lmh. Two mesh pore sizes (20 and 50μm) and three air scouring flow rates (150, 250, and 500mLmin) were tested at steady state. Under all the tested conditions, the SFD MBR effectively treated real municipal wastewater. The quality of the produced effluent increased for lower mesh size and lower air scouring intensity.
