Silver Ag ions is known as the material to sterilize about 650 kinds of harmful bacteria and microbes, by repressing their smooth metabolism function Nano as very small particle size means 10-9 (1nm)
Processed as small as nano particle size with normal Ag to have antibacterial and sterilizing function by using the technology to form and synthesize a nano particle in various solvents
Ultra Membranes with a pore size of 0.01 micron perform micro filtration. Microfiltration membranes remove all bacteria. Only part of the viral contamination is caught up in the process, even though viruses are smaller than the pores of a micro filtration membrane.
This is because viruses can attach themselves to bacterial biofilm.
Micro filtration can be implemented in many different water treatment processes when particles with a diameter greater than 0.1 mm need to be removed from a liquid.
