Japanese born, Paris based designer Jun Yasumoto developed this “phyto purification bathroom” together with Alban le Henry, Olivier Pigasse and Vincent Vandenbrouck.
Phyto purification bathroom.
The diagram illustrates how the bathroom become s a mini-eco-system using this natural filtering principle by recycling and regenerating the wastewater.
Phyto-purification is a natural water-recycling process which is commonly used in ecological purification systems. 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 bacteria 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.
