Influence of Membrane Pore Size on Performance and Efficiency at 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 size of particles that can traverse through the membrane, thus regulating the separation process. A smaller pore size usually results in higher 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 holds a crucial role in achieving a balance between filtration efficiency and operational performance for MBR systems.
