Membrane fouling is one of the major obstacles that hampers the application of membrane for conventional palm oil mill effluent (POME), agro-industrial wastewater treatment. Active fouling mitigation by introducing electricity across conductive membrane can suppress membrane fouling by enhancing the repulsive force between negative charge organic foulants and the membrane surface. This book discussed two carbon nanomaterials-graphene oxide (GO) and multi-walled carbon nanotubes (MWCNTs) as nanofillers in polymer to produce conductive membrane via the in-situ colloidal precipitation and direct blending methods. The presence of nanomaterials in GO/OMWCNTs membrane matrix had reduced the membrane surface roughness and formed a negative charge repulsive boundary which eventually enhanced the membrane's passive antifouling properties. Blending GO to MWCNTs membrane produced membrane with optimal conductivity which was suitable for active fouling mitigation. Generally, permeate flux decline was lessened with the application of electricity across the synthesised GO/MWCNTs membranes. This book supported that application of GO/MWCNTs membrane for active fouling mitigation was promising for POME treatment.
