    Ceramic membranes are increasingly used in water/wastewater treatment due to their excellent filtration/separation performance, mechanical, thermal and long-term stability. In this study, ceramic clay membranes coated with cobalt nanoparticles (Co NP) were produced to increase the antibacterial properties of ceramic membranes produced using clay, a natural and cost-effective material. The morphological structure of Co NP ceramic clay membranes was determined by SEM analysis and the surface of the ceramic clay membrane coated with Co NP gained a smooth surface feature close to homogeneity. The antioxidant activity of CoNPs was 69.26 % at 100 mg/L. Plasmid DNA was entirely degraded at 50 mg/L nanoparticle concentrations. At a concentration of 100 mg/L, α-amylase inhibition of 86.39 % was exhibited by the CoNPs solution. CoNPs exhibited significant antimicrobial activities against L. pneumophila subsp. pneumophila, E. hirae, and E. faecalis (Minimum Inhibition concentration (MIC):16 mg/L). The cell viability inhibitory effect of the NPs was 98.27 % at 20 mg/L concentration against E. coli. The antibiofilm activities of the CoNPs were determined 82.13 % and 71.67 % against S. aureus and P. aeruginosa, respectively. Furthermore, the E. coli elimination performance of CoNP coated on the solid surface of the ceramic membrane was obtained as 94.64 %. In line with all these results, it has been clearly proven that Co NP ceramic clay membranes can be used in water and wastewater treatment due to their convenient, cheap, and effective antibacterial properties. © 2024 Elsevier Ltd and Techna Group S.r.l.
