|Abstract: ||Silver has been in use since ages in India, as the ancient and Vedic Indians
have had the clear understanding on the disinfection properties of Silver.
They have used silver vessels to preserve drinking water and for offerings to
Based on the established fact above, this research is carried out using silver
at nano particle size, The advantage of using nano sized silver powder is that
it is almost equivalent to its ionic size and has a very large surface area per
unit volume. This area per volume is the key to perform disinfection action
on the disease causing bacteria. Disinfection takes place at sub nano level
and the microbe cell structure undergoes the process of lyses, during
disinfection cycle. The microscopic studies in this research have proven and
established the disinfection ability of silver beyond doubt.
The disinfection mechanism of silver at nano level is further streamlined in
an applicable format as an equipment, so that the silver disinfection system
could be readily used as a single unit. Various platforms carrying nano silver
have been developed using, ceramics, activated carbon, fabric, polymer and
cotton and synthetic fibers.
Each of the equipment developed is studied for its performance of
disinfection against time and flow along with study of leaching of silver in
treated water. Finally the results are analyzed and a conclusion is presented
at the end of the study with the future scope for further research.|
