The effect of graphene and graphene-oxide nanoparticles on the aerobic granular sludge wastewater treatment process
The responses of aerobic granular sludge (AGS) to the presence of graphene and graphene-oxide nanoparticles (G and GO NPs) at various concentrations (1, 5 and 10 mg/L) during biological wastewater treatment processes were investigated. Bioreactor performance and extracellular polymeric substance (EP...

| Summary: | The responses of aerobic granular sludge (AGS) to the presence of graphene and graphene-oxide nanoparticles (G and GO NPs) at various concentrations (1, 5 and 10 mg/L) during biological wastewater treatment processes were investigated. Bioreactor performance and extracellular polymeric substance (EPS) secretion were assessed. The results showed that the effects of G and GO NPs on bioreactor performances were dependent on the material and dose applied, especially in terms of chemical oxygen demand (COD) and phosphorus removal. Nitrite and nitrate removal rates were unchanged. The secretion of EPS, which could alleviate the toxicity of GO NPs, also changed. GO NPs were found to be more toxic than G NPs, indicating that structural changes may affect their activity. |
