Using a natural filtering principle called phyto-purification, commonly used in ecological purification systems, Jun Yasumoto’s Phyto-Purification Bathroom becomes a mini eco-system by recycling and regenerating the wastewater.
During its filtering process, the water goes through different steps :
- The rushes are planted in sand which filters larger particles. The root system of the rushes contain various bacterias which break down these particles for absorption by the plant.
- The reeds are planted next to the rushes as they have the ability to filter the heavy metals from the water.
- The floating water hyacinths draw through their roots some of the water borne particles which are still present in the water.
- The lemnas, which are also aquatic plants, bind to the remaining aquatic micro-organisms to complete the filtering process.
- Finally, a carbon filter stops the remaining micro-particles.
