This study investigated how well Moringa oleifera seed extracts clarify turbid water and wastewater — and which part of the seed does the work.
It compared mature and immature seed extracts, tested the soluble versus insoluble fractions, and even applied the extract to textile dye solutions.
Key findings
- Mature seed powder at 50 mg/20 ml reduced turbidity by 95% within two hours, and was more effective than immature seed.
- The soluble (aqueous) protein fraction — not the insoluble part — did the clarifying, with a positive link between protein content and purifying ability.
- The extract also clarified four textile dye solutions (Terasil Blue, Navy, Red and Yellow).
Caveat: a laboratory clarification study; dye and turbidity results depend on water and dye type.
