Pine Resin-Silver Lined Ceramic Filter¶

Ceramic Filtration • Est. CapEx: Low-cost / Locally fabricated

Technical Overview¶

A culturally adapted ceramic filtration device developed for the Navajo Nation, lining traditional clay pots with locally harvested pine tree resin and silver particles to disinfect drinking water while mitigating chemical interference common in regional groundwater.

Key Specifications & Engineering Parameters¶

Parameter	Specification
Category	Ceramic Filtration
Capital Cost	Low-cost / Locally fabricated
Primary Mechanism	Silver nanoparticles are incorporated into a pine tree resin lining applied to handmade clay pottery. As water is poured through the pot, the silver particles inactivate bacteria. The pine resin coating was specifically engineered to prevent silver from reacting with waterborne chloride and sulfide compounds, which otherwise form a 'poison layer' that reduces silver disinfection efficacy. The materials and construction process cost less than $10 per unit.
Target Scale	Household / Village Cluster
Standard Lifespan	10 - 20 Years
