Membrane Technologies for Wastewater TreatmentW. Gilbert O’Neal, Ph.D., P.E.


Membrane Biological Reactors (MBr)

  • Membrane Filtration of Activated Sludge Mixed Liquor

  • Eliminates clarifiers

  • Removes solids and turbidity from effluent

  • Reduced footprint

  • Tolerates

    • High SRT, MLSS

    • Filamentous Bacteria

Zero Liquid Discharge (ZLD)

  • Water Reuse (90-95%)

  • “Dry” Residual Disposal

  • System Components

    • Biological Treatment

    • Chemical Treatment

    • Macro Filtration

    • Membrane Filtration (UF and RO)

    • Evaporation (MEE)


Application

  • Regulatory Restrictions

    • India

  • Resource Limitations

  • Discharge Limitations

  • Sustainability Goals
