Nano-Ag has good potential for application in POU treatment.
It can improve water quality for high-end use, or provide
another barrier against waterborne pathogens for
vulnerable population. Commercial devices utilizing nano-Ag
are already available, e.g., MARATHON and Aquapure systems.
Nano-Ag has also been incorporated into ceramic
microfilters as a barrier for pathogens, which can be employed
in remote areas in developing countries
