Enhanced performance of graphene-oxide polyethersulfone nanocomposite membrane wastewater and its fouling mechanism
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-poly...

| 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 and heavy metals removal. Fouling mechanisms are investigated for lead-containing wastewater using pore blocking models. According to the findings, cake filtration outperformed all other filtration mechanisms, with the highest R2 at all transmembrane pressures applied. Furthermore, the experimental results confirmed that adding GO to the membrane enhanced pure water flux and heavy metals removal and can be applied as a novel method for preparing high performance membranes in wastewater treatment. |
