Stormwater Biochar Filtration Socks¶
Rainwater & Storage • Est. CapEx: $112.50 USD • Lifespan: 7–15 Years
Technical Overview¶
Engineered tubular geotextile socks filled with high-performance, stormwater-grade wood biochar designed for passive filtration of urban and industrial runoff. Deployed in municipal stormwater infrastructure, swales, and drain inlets, the system removes dissolved heavy metals and sediment without chemical additives.

| Primary Mechanism | As stormwater flows through the vascular pore network of the wood biochar media, dissolved priority metals (copper, zinc) and organic pollutants adsorb onto carbon surfaces via surface complexation and ion exchange. Iron-doped variants add redox chemistry to target specific organic pollutants and dyes, increasing removal efficiency per unit volume over conventional sand/compost blends. |
