Summary With an increase in use of nanoparticles (NPs) in day to day products, these particles eventually enter the wastewater treatment plant and get removed from the effluent while getting accumulated in the sludge at ever increasing concentrations. These NPs have a potential for causing inhibition in sludge digestion processes. Therefore, this research focused on the effects of cerium (IV) oxide (CeO2) and zinc oxide (ZnO) NPs on biogas production from sludge. The inhibition effects were investigated by studying toxicity of the said NPs on Escherichia coli. The results showed that CeO2 and ZnO NPs showed some degree of inhibition in biogas production with 65.3% biogas reduction at ZnO NPs at 1000 mg/L concentration. Conversely, CeO2 at low concentration of 10 mg/L lead to an increase biogas generation by 11%. The tolerable exposure concentrations for ZnO were determined to be 100 and 500 mg/L, where the system could overcome the inhibition effect after 14 days of incubation. The bacterial toxicity test showed that both nanoparticles were toxic for bacteria leading to biogas reduction.
