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