Demonstrates effective water purification technology in Kogi State, suggesting a sustainable solution for clean water access.

The study aims to develop a cost-effective water purification technology using Moringa oleifera and agricultural waste.
Combined protein-based coagulation from Moringa oleifera seeds with activated carbon filtration.
Employed microwave-assisted activation with M. oleifera leaf extract as an activator.
Utilized salt and water extraction methods to obtain coagulant proteins.
Tested the purification system with River Niger water samples.
Achieved 97.3% turbidity reduction with salt extraction of coagulant.
Activated carbons had surface areas of 847 to 1,164 m²/g.
Reduced turbidity from 287 NTU to below 5 NTU in tested water samples.
Eliminated E. coli and total coliforms in the treated water.
Estimated treatment cost was $0.076 per litre, significantly lower than commercial options.
