Isabella Reboli

I am a student at the State Institute of Higher Education in Agriculture, Agri-food and Agro-industrial “Giovanni Raineri” in Piacenza, Italy. I was inspired by my desire to help others, particularly communities in developing countries. Through this project, I developed a water filter that purifies contaminated water using the seeds of the Moringa oleifera tree, offering a low-cost and sustainable solution for access to safe drinking water.

Moringa: The filter That Nature Gives Us

The project stems from the desire to realise a fundamental right of every individual: access to clean water. The results obtained indicate that the answer to this global challenge lies in the integration of natural resources and sustainable technology. Precise data has emerged from the experiments carried out: • laboratory analysis: tests on standardised samples recorded a 99% reduction in bacterial load and an 82% reduction in PFAS (PFOA, PFOS, HFBA). These results demonstrate the effectiveness of Moringa oleifera not only as a coagulant, but also as a bio-adsorbent for complex chemical pollutants; • field trial: the prototype, assembled using reused components, demonstrated a bacterial load reduction capacity comparable to that of the laboratory tests, proving suitable for meeting the…
