| Summary: | Membrane fouling is still a great challenge in filtration process for wastewater treatment which limits its
technical and economic performance. To prevent and control on fouling it is important to understand the filtration behaviour
and fouling mechanism. In this study, a new graphene oxide-polyethersulfone nanocomposite (GPN) membrane is
fabricated and later the performance and rejection of heavy metals removal were studied using a dead-end filtration system.
The performance of the fabricated GPN membrane was measured by evaluating pure water flux, salt and heavy metals
removal. Fouling mechanisms are investigated for lead-containing wastewater using pore blocking models. From the
results, cake filtration was found to dominate all other filtration mechanisms with the highest R2
at all the applied
transmembrane pressure. Furthermore, the experimental results confirmed that adding GO to the membrane improved pure
water flux, and heavy metals removal, and can be used as a novel method for preparing high performance membranes in
wastewater treatment. |
