SODIS (Solar Water Disinfection)¶
Membranes & Advanced Filtration • Est. CapEx: Low-cost / Locally fabricated
Technical Overview¶
SODIS is a simple, low-cost household water treatment method that uses solar energy to disinfect microbially contaminated drinking water. It is recommended by the WHO and suitable for low-income communities and emergency settings.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | Membranes & Advanced Filtration |
| Capital Cost | Low-cost / Locally fabricated |
| Primary Mechanism | Microbially contaminated water is filled into transparent PET bottles and exposed to full sunlight for at least 6 hours. Solar UV-A radiation damages pathogen DNA, while increased water temperature creates synergistic disinfection effects, inactivating bacteria, viruses, and some parasites. |
| Target Scale | Household / Village Cluster |
| Standard Lifespan | 10 - 20 Years |
