- •
Aggregation and adsorptive removal of CuO NPs in wastewater system were studied.
- •
Possible impacts of CuO NPs on biofilm were determined by assessing O2 penetration.
- •
50 mg/L CuO NPs inhibited the microbial activities only in biofilm outmost layer.
- •
Protective mechanisms of the EPS matrix were discussed.
