Influence of Membrane Pore Size to Performance and Efficiency throughout Ultrafiltration MBR Systems

Membrane pore size is a critical parameter influencing 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 modifying the separation process. A smaller pore size usually results in greater removal efficiency for dissolved solids and microorganisms, but may also lead to reduced permeate flux due to increased resistance to flow. Conversely, larger pores permit a higher flux rate but may compromise the removal of smaller contaminants. Optimizing membrane pore size is a crucial role in achieving a balance between filtration efficiency and operational performance within MBR systems.
