Overview

Low-cost, solar-powered water purification system using TiO₂ nanoparticles for photocatalytic treatment in rural communities.

Environmental Remediation / Water Purification

Waterborne diseases (cholera, typhoid, dysentery)

Experimental Conditions

Solar irradiation: 6-8 hours/day. Flow rate: 5 L/hour. Batch size: 200 L per reactor. Ambient temperature.

Results & Findings

95% removal of organic contaminants, 99%+ bacterial reduction, 80% heavy metal removal. Treatment capacity: 50,000 L/day. Cost: $0.02 per liter.
Organic Pollutant Removal: 95% Bacterial Reduction: 99%+ Heavy Metal Removal: 80% (Pb, As, Cd) Treatment Capacity: 50,000 L/day Cost per Liter: $0.02 System Lifespan: 5+ years Communities Served: 15 villages (~7,500 people)

WHO water quality standards met in >95% of samples (n=450 tests). Cost-benefit analysis: 87% savings vs conventional treatment.

Successful

Insights

Seasonal variation in solar irradiation. Community training and maintenance. Catalyst replacement logistics in remote areas.
Integration with UV-LED for night operation. Mobile unit development. Exploring nitrogen-doped TiO₂ for visible light activity.

Safety Considerations

No nanoparticle leaching detected in treated water. TiO₂ is GRAS-certified. Regular water quality monitoring confirms safety.
