معالجة مياه الشرب الميكروبيولوجية باستخدام مرشحات البولي بروبلين غير المنسوجة المطعمة بالنانو فضة الحيوية

الملخص EN

The bio-silver nanoparticles were prepared by using Fusarium oxysporum on a liquid medium and obtained a solution containing the Bio-Nano silver particles.

⁽¹⁾ The presence of silver particles was confirmed using an (SEM).

The non-woven polypropylene filter was manufactured by the Melt blown method with a porosity of 5 microns and was grafted with Bio-Nano silver particles during manufacture by spraying and depositing the Bio-Nano silver solution on the filter during the wrapping of the filament layers in the manufacturing stage and the presence of Nano silver on the polycarbonate filter Polypropylene using (SEM, EDX).

The efficiency of the filter fed with Nano silver bio-based on microbial resistance was also evaluated and compared with the filter not inlaid with Nano silver particles at a flow rate of 3 liters / hour and after 7 hours of filtration with a bacterial load of 3¹⁰ units of bacteria (E-coli) the water was coming out of the filtration.

Contains zero of (E-coli) bacteria.

The results also showed that after the filter was in the water for 7 hours, no Nano silver particles were lost in the water leaving the filtration process.

The effect of bio-nanoparticle grafting on the size of the interspace (porosity) of the filter was also studied by analyzing 10 microscopic images (SEM).

The average pore size was calculated for the filter inlaid with Nano silver.

The results showed that grafting with Nano silver bio-silver caused an approximate decrease of three times.

The size of the pores of a polypropylene filter.
