Domestic wastewater pollutes rivers and harms aquatic life and people. This study explored an unusual pairing — a magnetic field and Moringa oleifera seed powder — to treat domestic wastewater from a university hostel, testing each method alone and in combination.
Published in the open-access Journal of Applied Sciences and Environmental Management, the team passed wastewater through a 100 mT magnetic field and dosed it with 100, 150 and 200 mg/L of moringa seed powder, then measured physical, chemical and bacteriological properties.
Key findings
- Moringa seed powder reduced turbidity and improved the physical, chemical and bacteriological quality of the water.
- Combining the magnetic field with moringa enhanced treatment compared with either alone.
- Higher moringa doses generally improved clarification within the tested range.
Caveat: a small-scale study on hostel wastewater; specific reduction percentages depend on dose and contact conditions.
