Biochar-Zeolite Composite Gravity Filter¶
BioSand & Media Filters • Est. CapEx: $10 USD • Lifespan: 7–15 Years
Technical Overview¶
An enhanced appropriate-technology filter combining biochar and zeolite to target chemical contaminants, heavy metals, and ammonia that basic sand-and-charcoal systems miss. Intended for homesteaders and practitioners with access to natural mineral and biomass resources.
