Making Biochar Water Filters

Biochar Water Filter Workshop

Image: Kearns et al, 2023

Learn to build decentralized water filtration systems using biochar - a carbon material that can be produced locally from agricultural waste. These filters use adsorption to remove contaminants, offering a sustainable alternative to commercial activated carbon filters.

What You'll Learn

• How biochar filtration works through adsorption
• Producing biochar from biomass using simple equipment
• Assembling multi-stage filtration systems
• Sizing filters for household or community use

Workshop Details

Ideal for anyone interested in water resilience, off-grid living, or community preparedness. Biochar filters can process 300-2000+ liters daily depending on design, using materials that can be sourced and produced locally.
