Abstract

Key findings

  • The membrane exhibited a high flux and rejection rate for microbial cells, with a rejection rate of 99.5%.
  • The membrane's performance was stable over 24 hours of operation, with minimal decline in flux and rejection rate.
  • The membrane's surface morphology and pore size distribution were characterized using SEM and AFM, respectively.
