Water treatment systems
Among the research activities of Proambiente, particular attention is addressed to the development and application of new techniques and methods for the purification / treatment of wastewater, in particular with ionizing and non-ionizing energies. The techniques defined A.R.P. (Advanced Remediation Processes) use different power energies (depending on the flows and volumes of wastewater to be treated) to obtain a high degradation capability of organic compounds from wastewater.
The use of equipment such as Electron Beam and Gamma Cell available at ISOF-CNR institute (partner of the Consortium) has been fundamental to increase the know-how of their use in the purification of water coming from civil waste and from agriculture, in order to favour their possible reuse.
In particular, the researchers of Proambiente Consortium test and develop innovative tools through the irradiation of aqueous solutions with different energy sources:
- accelerated electrons,
- gamma rays,
- UV rays.,
that determine the production of OH radicals, which are the basic promoters of the degradation of polluting compounds present in wastewater. It involves mechanisms of fragmentation and oxidation that lead to the formation of CO2, thus reducing the amount of organic carbon.
These technologies are used by Proambiente researchers to detoxify the organic substances present in the waters and in particular the emerging organic pollutants (crop protection products, drugs, UV filters).
The continuous improvement of the techniques and their evolution in different fields has given Proambiente the stimulus to start the design and construction of a first operational prototype for the degradation of agricultural crop protection products, used in agriculture by means of spray machines, which remain on the bottom of the tanks at the end of the process.
