Influence in Membrane Pore Size to Performance and Efficiency throughout 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 permeate through the membrane, thus modifying the separation process. A smaller pore size typically results in increased removal efficiency for dissolved solids and microorganisms, but may also lead to reduced 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 in MBR systems.
