Performance of ceramic filter coated with silver nanoparticles in removal of Escherichia Coli from drinking water

Nanotechnology is a field of applied knowledge. The use of nanotechnology and silver nanoparticles has been studied in recent years to control bacterial diseases. This study aimed to investigate the antibacterial effect of ceramic filter pads containing silver nanoparticles in the control of E. coli.

The present work was an experimental study. Silver nanoparticles were synthesized by dissolving silver nitrate (AgNO3) in ethanol and reducing silver in an alcoholic medium. Characteristics of filters were evaluated using BET, SEM, XRF, and XRD tests. Ethical considerations were observed in all stages of the study.

The results showed that the removal efficiency of E. coliwas 36.2-66.7% by conventional filters and reached up 99-100% by ceramic filters coated with silver nanoparticles

The results of this study showed that ceramic filter media containing silver nanoparticles have considerable antimicrobial effects. By generalizing the results of this study, these ceramicfilter media can be used in the treatment and filtration of unsafe water and thus control of pathogens in drinking water.
