Monitor the purified wastewater battery charger in real time to verify the suitability of the water for irrigation.
The innovative system was installed by Enea, in collaboration with the Hera Group, at the Cesena urban wastewater treatment plant.
The system, we read in the online periodical Enainform@, also allows you to verify the nutrients supplied to the field through irrigation and, consequently, to adapt fertilization plans, reducing the use of synthetic fertilizers.
Presented a few days before World Water Day which is celebrated every year on March 22, "the new monitoring system was created as part of the Pnrr projects benefiting the agricultural sector for the production of nutritional elements and fertilizers deriving from agri-food waste and sewage sludge".
In addition to the identification of bacteria such as Escherichia coli via enzyma in less than two hours, compared to the 24 hours required by official procedures, the system allows the manager a greater frequency of monitoring, the real-time evaluation of the appropriate intended use and the opportunity to rapid intervention, in line with the new European regulation on minimizing associated risks.
"The irrigation reuse of purified waste water represents a practice to be pursued with a view to closing the water resource cycle as a measure to counteract the reduction in water availability, especially in correspondence with the increasingly frequent periods of drought", highlighted Luigi Sciubba of the Enea Laboratory of Peruso Technologies and efficient management of water and wastewater.
