Influence of Membrane Pore Size to Performance and Efficiency at 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 permeate through the membrane, thus controlling the separation process. A smaller pore size typically results in greater removal efficiency for dissolved solids and microorganisms, but may also lead to lower 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 holds a crucial role in achieving a balance between filtration efficiency and operational performance within MBR systems.
