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.
