Pathogen Removal in Moringa oleifera Modified Sand Columns

Ziyuhan Wang
Developing a drinking water treatment device with Moringa oleifera seeds enables a locally-sourced and less expensive alternative to traditional water purification methods. Moringa oleifera seeds contain an antimicrobial cationic peptide that kills bacteria by fusing cell membranes. Moringa sand column experiments suggests the particle removal and column lifetime can be predicted using the Clean Bed Filtration theory. This f-sand filter demonstrated  >8 log removal of Escherichia coli compared to <0.1 log removal for bare sand.
