Phyto-purification basin: an environmentally friendly solution for your home
All too often, our wastewater has a harmful impact on nature, without us realising it. This becomes particularly problematic in rural areas without mains drainage. Phyto-purification basins exploit the filtering power of certain plants to effectively clean up wastewater. Focus on the Aquatiris phyto-purification basin.
How does a phyto-purification basin treat wastewater?
Phyto-purification is an individual wastewater treatment system that uses the bacteria present in the root systems of filtering plants (plant filters) to treat wastewater from kitchens and toilets. A phyto-purification system works on the basis of a simple process, similar to that of a traditional wastewater treatment system. The plant consists of two strategically positioned basins.
The pre-treatment of wastewater is the first stage of the phyto-purification basin process. It can take place in a septic tank or in a vertical bed with persistent phyto-plants (reeds). In this phase, the liquid matter is separated from the solid substances.
The large particles are thus trapped on the surface by the root network of the plants, and then, over time, they turn into compost. The polluting effluents infiltrate in order to be absorbed by the root system of the purifying plants.
This phase plays a key role in the elimination of nitrates and phosphates. At the same time, a biological phenomenon occurs: the sludge at the base of the plant roots decomposes thanks to the action of bacteria. This sludge is transformed into nutrients that can be assimilated by the plants which in turn provide the oxygen essential for the survival of the bacteria.
Ultimately, the water filtered by this ecological solution is clean, free of unwanted odours and ready to be reused for watering the garden. In addition, the compost recovered from the surface of the first phyto-purification basin can be used to fertilise the soil in flowerbeds and around ornamental plants.

What are the advantages of a phyto-purification tank?
More and more households not connected to the collective sanitation network are choosing phyto-purification because of its many advantages.
Ecological individual sanitation solution
This natural sanitation basin differs from the traditional septic tank which relies mainly on chemicals. The phyto-purification basin therefore presents no risk of contamination or pollution for the environment (water and soil). It is also an autonomous sanitation station that operates without fossil energy.

Phyto-purification stations can be easily integrated into the home
Phyto-purification basins are individual systems that do not generate any unpleasant odours. Thanks to the complete breakdown of materials in contact with oxygen, the process produces water vapour and humus, making the result odourless. The risk of disturbing your neighbours is therefore virtually non-existent.
What’s more, a well-maintained phyto-purification basin has the advantage of enhancing your outdoor space (garden) thanks to the purifying plants that will act as ornaments. There is also no need to replant the plants throughout the lifespan of the basin. This makes the management of your ecological basin very practical, allowing you to integrate it perfectly into your garden.
Economical sanitation system
The installation of a natural purification basin is an affordable investment compared to other individual purification options. Aquatiris offers you the possibility of installing a phyto-purification system at a competitive price of between 11,000 and 16,000 euros. The initial investment may seem substantial. However, it remains an economically profitable investment in the long term.
Once in place, our ecological solution saves you the expensive emptying and maintenance costs associated with traditional sanitation tanks. Contact us now to receive a free quote and adopt the ecological and sustainable approach to sanitation.
How do you install a phyto-purification basin in your home?
Would you like to install an ecological solution in the outdoor area of your house? Several criteria must be taken into consideration. You must already have at least 2m² per population equivalent to install your phyto-purification basin. You must also take into account the number of people living in your house. This is called the population equivalent (PE). It is very simple to calculate. A 7m² room is equivalent to one PE.
A study of the soil will then be carried out to set up this sanitation system. It will help determine which filtering plant will be integrated into the basin. A visit will also be made to determine the installation of the ecological solution.
When setting up the phyto-purification basin, a lift pump will be necessary if the slope of the land is insufficient. It will be used to send a sufficient quantity of wastewater so that it is distributed evenly over the vertical filter where it will drain away.
If you want to install these phyto-plants in your garden, trust in the expertise of Aquatiris. We can offer you an environmentally friendly solution that will help you respect the environment.
