Community Slow Sand Filter¶
BioSand & Media Filters • Est. CapEx: Low-cost / Locally fabricated
Technical Overview¶
A community-scale water treatment system using sand and biological processes to produce high-quality drinking water. Used in both developed and developing countries with simple operation and minimal maintenance.
Key Specifications & Engineering Parameters¶
| Parameter | Specification |
|---|---|
| Category | BioSand & Media Filters |
| Capital Cost | Low-cost / Locally fabricated |
| Primary Mechanism | Water passes slowly through a bed of sand where a biological layer (schmutzdecke) forms, trapping particulates and digesting pathogens. Cleaning is done by scraping the top layer of sand rather than backwashing. |
| Target Scale | Household / Village Cluster |
| Standard Lifespan | 10 - 20 Years |
