Influence in Membrane Pore Size on Performance and Efficiency at 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 permeate through the membrane, thus controlling 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 enable 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.
