What are the benefits of a phytodepuration plant?

After having understood what phytodepuration is and having discovered all the phases of the project (phases 1-2-3 and phases 4-5-6-7), we can now conclude our in-depth study by analyzing the advantages that this plant entails.

In this article we will also talk about the required maintenance and you will finally be able to download the complete project in pdf!

Ordinary maintenance

i.e. cleaning of the site with annual mowing of the terrestrial biomass (marsh straw) and algae and transport of the same to the company biogas plant where present.

Extraordinary maintenance and plant life

The plant is extremely simple: it consists mainly of a sheet, sand, gravel and plants.

The parts that may need extraordinary maintenance are:

  • Sheet: this is the type of sheet normally used for landfills and ponds to contain wastewater, with a minimum lifespan of 30-50 years.
  • Substrate: composed of sand, gravel, and stones. The solid separation and settling phases ensure that only the liquid parts reach the tanks, thus avoiding clogging.

If a tank were to clog, there would be no problem in intervening, because it would be enough to close the line to be controlled and work on that one.

Having 12 separate lines, we have the possibility of carrying out maintenance without compromising in any way the purification of the plant.

The benefits

FOR AGRICULTURE AND LIVESTOCK

Development of a technology that will allow many livestock farms to reduce their slurry management and therefore production costs. Onerous land dedication for slurry disposal will no longer be necessary. A farm will be able to sell land that was not part of its core business and invest it in animal husbandry. There should be no more costs for renting or selling land above its true value (again because of the need for sewage disposal).

FOR THE ENVIRONMENT

The advantages for the environment are enormous!

The idea of transforming a degraded and polluting area into the opposite is at the heart of the design effort. Thousands of above-ground concrete ponds will be replaced by hectares of reeds and lakes with O² development instead of greenhouse gases (mainly CH4), with wetlands where frogs and waterfowl will find outlets and small oases instead of degraded areas.

Another advantage for the environment is the safety of these plants. The law on sewage disposal stipulates a nitrogen load per hectare of land, but this is all on paper; in practice, sewage is spread more on land adjacent to farms than far away, causing groundwater pollution.

With phytodepuration we have a residence time that allows us to compensate for weeks of continuous rain and cold months that extend beyond the season. Of all the existing purification plants, phyto-purification is a 100% natural process. There is no human intervention or addition of chemical solutions. The plant works slowly and naturally on its own, which means greater safety!

Once the system has been installed, the only thing you must do is check for blockages (in which case you can simply bypass the faulty line and act). Compared to traditional technologies such as mechanical oxygenation, biodiscs or activated sludge, this purification system cannot shut down, so the plant always works even in the absence of electricity. In addition, it can absorb hydraulic and organic overloads because they would be averaged over the next 6 months.

This pilot project is the beginning of a path that leads man to work with nature for nature’s sake and not against it, as has been the case up to now (purifying sewage with cement/electricity and throwing ammonia/methane into the atmosphere are both polluting and uneconomic).

The natural continuation of the project will be to purify the sewage of cities and towns, creating areas where it will be possible to use them for recreation-parking. In fact, one of its goals is to purify on site through nature and the soil without eutrophicating our streams, rivers, and sea etc.

FOR FARMERS

In the face of the inconvenience of construction work, the farmer will find himself with a “natural” plant that will allow him to considerably reduce the costs of wastewater disposal.
