Article Synopsis
  • The study evaluates the performance of a membrane bioreactor (MBR) in treating petroleum refinery effluent, focusing on organic matter removal, membrane fouling, and membrane lifespan.
  • The MBR effectively reduced harmful substances like COD, NH-N, and phenol to meet water reuse standards, with organic matter removal attributed to biological processes and adsorption.
  • Findings indicate that membrane fouling primarily stems from a soluble fraction of mixed liquor, and the expected membrane lifetime is around 7 years based on permeability decline.

In this article, the long-term use of cationic polyelectrolyte to improve the sludge filterability and to control membrane fouling in bioreactor membrane while treating refinery effluents have been evaluated in pilot scale. Corrective and preventive cationic polyelectrolyte dosages have been added to the membrane bioreactor (MBR) to evaluate the membrane fouling mitigation in both strategies. The results have confirmed that the use of the Membrane performance enhancer (MPE) increased the sludge filterability and reduced the membrane fouling.
