Abstract
Disinfection and elimination of pathogenic
microorganisms from liquid can be achieved
by filtration process using antibacterial filter media.
The advent of nanotechnology has facilitated the
introduction of membranes consisting of nano-fiber in
filtration operations. The melt electro-spun fibers due
to their extremely small diameters are used in the
production of this particular filtration medium. In this
work, antibacterial polypropylene filter medium containing
clay particles and nano-TiO2 were made using
melt electro-spun technology. Antibacterial performance
of polypropylene nano-filters was evaluated
using E. coli bacteria. Additionally, filtration efficiency
of the samples in terms fiber diameter, filter
porosity, and fiber distribution using image processing
technique was determined. Air permeability and dust
aerosol tests were conducted to establish the suitability
of the samples as a filter medium. It was concluded
that as far as antibacterial property is concerned, nanofibers
filter media containing clay particles are preferential
to similar media containing TiO2
nanoparticles.
