Everything you can imagine, nature has already created it
We have chosen this phrase by A. Einstein, because it synthesizes the main path of our daily action, that is to observe and study nature, the answers and solutions are already there and as science and technology advances, we realize that in nature all this already exists and works.
This preamble to introduce the Phytopurification, is the effective purification system and at the lowest cost, always present in nature also performs several other functions on which for brevity of space we do not dwell on ... but we are always available to talk to you.
Water Nursery, has always been attentive to technological developments related to greenery. For this reason, for example in the field of Phytopurification, through studies and experience gained over the years, in addition to supplying plants for civil and industrial plants, has developed the necessary know-how to best advise (if required), our customers.
Water Nursery, has always available large quantities of plants for Phytopurification.
Phytopurification means the purification of water with plants (phito = plant).
In reality, plants act after the bacterial flora that has formed, has broken down and/or modified the pollutants making them assimilable by the plants.
The Phytopurification plants (constructed wetlands), can be used as secondary treatment, i.e. as a real purification process downstream of the primary treatment, or as tertiary treatment downstream of a traditional purification plant whose effluents do not reach the limits imposed by the regulations.
Phytopurification techniques can be classified according to the type of plants used (algae, microphytes, macrophytes), or more simply according to whether the flow is horizontal, vertical or mixed.
free water surface systems (FWS - Free Water Surface)
sub-surface or submerged flow systems (SFS: Subsurface Flow Sistem)
in turn divided into horizontal submerged flow systems (SFS-h or HF: Subsurface Flow System - horizontal)
and vertical submerged flow system (SFS-v or VF: Subsurface Flow System - vertical)
The most used Phytopurification system is the one with emerging rooted macrophytes with submerged flow. This system is the one that normally has the most advantages, such as a greater contact surface for the microorganisms responsible for the processes. The most commonly used Phytopurification systems for the treatment of domestic wastewater are those with emerging rooted macrophytes and among them those with submerged flow are those that have had the greatest development. The medium represents the support on which emerging rooted macrophytes take root and bacterial biofilms that trigger basic biological and chemical transformations proliferate.
The most used plants in this type of systems are those called aquatic macrophytes(higher plants).
The most used essence in the whole Europe is the Phragmites australis,or marsh straw, for its role of oxygen pump; in fact, this is an elophyte that has the characteristic of carrying the atmospheric oxygen deep into the filling medium thanks to its long rhizomes, creating oxidized microzones that are colonized by aerobic bacteria; this activity is very important in submerged flow systems.
In surface flow systems, all species of aquatic macrophytes that tolerate high levels of trophy and pollution can be used (Carex spp., Scirpus spp., Shoenoplectus spp., Caltha palustris, Alisma plantago-aquatica, Lythrum salicaria, Ceratophyllum demersum, Myriophyllum spicatum, ecc.)
