Harvesting Potable and Storable Water With Moringa Seeds and Sand

We propose to design and implement a point-of-use process for water purification and storage in developing nations. Our research innovates on an existing technique for purifying water with seeds from the Moringa oleifera (Moringa) tree. Mixing water with crushed Moringa seeds clarifies and disinfects water; however, a critical challenge exists: Crushed Moringa seed leaves proteins and organics in water that bacteria use for food, and so the purified water cannot be stored. Therefore, the purification must be done daily, which is difficult and often not done.
