Living Filtration System is a biomimetic agricultural drainage solution by Team Penthouse Protozoa from the University of Oregon. It prevents nutrient runoff by mimicking soil microbial ecosystems, keeping fertilizers in fields to reduce pollution while maintaining crop yields.
Natural Inspiration
Inspired by earthworm burrows and protozoan filtration in healthy soils, the system uses helical channels lined with biofilm habitats. These promote denitrification and phosphorus uptake, trapping 80-95% of excess nutrients before they reach waterways.
Design Elements
Installed in tile drains, spiral modules create low-flow zones for microbial action. Native plants and aggregates enhance bioremediation. It retrofits existing infrastructure affordably.
| Module | Biomimicry | Function |
|---|---|---|
| Helices | Worm Burrows | Slow flow, boost microbes |
| Biofilm Layers | Protozoa Habitats | Nutrient capture |
| Plant Roots | Soil Ecosystems | Final polishing |
Adoption Potential
Finalist in the Biomimicry Global Design Challenge, it catalyzes regenerative farming by cutting eutrophication without yield loss.
