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

Membrane pore size is a critical parameter determining the performance and efficiency of ultrafiltration membrane bioreactor (MBR) systems. The pore size directly impacts the magnitude of particles that can pass 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 decreased 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 plays a crucial role in achieving a balance between filtration efficiency and operational performance within MBR systems.
