If we have a product which contains bacteriophages which specifically kill pathogenic bacteria in contaminated water, will it work efficiently? Will people use this product for water disinfection?
I think the problem with this use could be that bacteriophages only kill a limited range of specific species of bacteria, but not all pathogenic bacteria species that could theoretically be in contaminated water.
From the water engineering side it is necessary to have a effective disinfection of all potential pathogens from water before it can be safe for drinking water.
