Influence of Membrane Pore Size for Performance and Efficiency in Ultrafiltration MBR Systems
Membrane pore size is a critical parameter affecting the performance and efficiency of ultrafiltration membrane bioreactor (MBR) systems. The pore size directly impacts the magnitude of particles that can traverse through the membrane, thus modifying the separation process. A smaller pore size typically results in increased removal efficiency for colloidal solids and microorganisms, but may also lead to lower permeate flux due to increased resistance to flow. Conversely, larger pores allow a higher flux rate but may compromise the removal of smaller contaminants. Optimizing membrane pore size plays a crucial role in achieving a balance between filtration efficiency and operational performance in MBR systems.
