The JAMEBI Solar Water Pasteurizer is a solar-powered device designed to provide safe drinking water by eliminating harmful pathogens through the process of pasteurization. It is marketed under the brand name SunLifeWater and is intended for use in off-grid, resource-limited, and emergency contexts.[1][2]
The JAMEBI Solar Water Pasteurizer uses the heat of the sun to raise water to pasteurization temperatures, thereby killing bacteria, viruses, and protozoa without the need for electricity, fuel, or chemical additives. The device is designed for household and community-scale use, particularly in tropical and subtropical regions with high solar exposure.[3]
Technology[]
The system is a flow-through solar thermal pasteurizer. Water passes through a solar collector where it is heated to temperatures sufficient to inactivate pathogens. Unlike boiling, pasteurization requires lower temperatures (typically above 65 °C), making it more energy-efficient. The device has been independently tested and rated by the World Health Organization (WHO) as providing "Comprehensive Protection Two Star," meaning it removes over 99.99% of pathogens from drinking water.[4]
Performance[]
- Bacteria reduction: > 6 log reduction (99.9999%)
- Protozoa reduction: > 6 log reduction
- Virus reduction: > 4 log reduction (99.99%)
- Capacity: Up to 250 litres per day in full sun conditions
- Longevity: Estimated lifespan of 20 years with minimal maintenance[2]
Applications[]
The pasteurizer is intended for:
- **Household use** in sunny, off-grid regions
- **Community-scale water supply** in tropical and subtropical areas
- **Emergency and disaster relief**, where it can be deployed rapidly as a flat-pack kit
- **Long-term sustainable water supply**, with a lifetime cost estimated at less than USD $3 per 1,000 litres of water treated[3]
Advantages[]
- Operates without electricity, fuel, or chemicals
- Zero operational costs after installation
- Robust design with no fragile glass components
- Can be stored for decades and deployed quickly in emergencies
- Provides safe drinking water within hours of setup[1]
