How does it work

Behind this word lies a natural individual purification solution. Phyto-purification (see definition) takes indeed advantage of the purifying power of plants and of the aerobic bacteria (which need oxygen and do not emit bad odors). This bacteria eats the organic matter and transform it into mineral matter that can be assimilated by plants. These plant species are able to absorb pollutants such as phosphates. The most commonly used plants are bamboos and reeds.

Wastewater is rated in several stages:

  • A first treatment through the gravel and the roots of the plants retain the coarse particles on the surface.
  • Treatment of chemical compounds through several basins made up of substrate and plants that absorb nitrates and phosphates.
  • Biological treatment because bacteria transform deposits into plant nutrients.

Phyto-purification reduces pollution of surface and groundwater.

As a reminder, black water is the water that comes from the toilets. Grey water comes from household waste.
