Effectiveness of silver and copper infused ceramic drinking water filters in reducing microbiological contaminants

A series of bench-scale experiments were conducted on ceramic filters with various amounts of silver and/or copper nanoparticles fired-in during the manufacturing process. The experiments were designed to determine the efficacy of the filters on the removal of pathogens from drinking water. Escherichia coli and MS2 were employed as non-pathogenic surrogates for pathogenic organisms. Experiments were run on 23 ceramic filters – 10 replicates, …
