PROJECT PROGRESS

ACTION B1 COMPLETED
Design, construction and refinement of LESSDRONE prototype
The design and assembly of the equipment making up the LESSDRONE were completed. The automatic positioning of the hull and the analysis instrumentation are connected through a specific software that manages the different sampling phases. The position of the drone is managed by a Global Positioning System (GPS) that allows to identify the points to be monitored directly on the map.
The hull consists in 6 independent inflatable sections that allow the floatation of the frame on which the control boxes and monitoring equipment are anchored. Under the frame and within the area delimited by the inflatable sections, the collection hood of the offgas was placed for the measurement of the incoming flow.

ACTION B2 COMPLETED
Testing of LESSDRONE
The drone has been tested under different operating conditions. The first tests were carried out in the laboratory to verify the functionality of the instrumentation and sensors, while at the same time floating tests and tests on the engines were carried out in a pool specially set up outside the laboratory. Subsequently, the tests were carried out inside the oxidation tanks of the CUOIODEPUR WRRF, in order to verify the reliability and the response of the system, both for the instrumentation part dedicated to sampling and for the positioning one.
After completing the design and assembly phase of the LESSDRONE, the drone testing tests were carried out to verify the functionality of the remote movement and of the measurement instrumentation. The control tests have given positive results, so far the project is proceeding without problems, according to the scheduled time.
ACTION B3 STARTED
Procedure development for off-gas monitoring with LESSDRONE
Action B3 has just started, in which the work program for the tests to be carried out with LESSDRONE at CUOIODEPUR WRRF has been defined. In particular, the duration of the tests, the sampling frequency, the operating conditions and the procedures for measuring the efficiency of oxygen transfer and the emissions of greenhouse gases were identified. The objective is to evaluate the dynamics that influence the parameters analyzed in order to optimize the aeration process. In the next 15 months, 6 weekly measurement campaigns are scheduled, distributed throughout the year to cover the different environmental and load conditions at the entrance to the plant.
DISSEMINATION AND NETWORKING ACTIONS
The project dissemination and networking actions continue. On November 7, 2018, the third didactic visit with the students of the Environmental Microbiology course at the University of Pisa took place at the CUOIODEPUR WRRF. During the visit, the functioning of the plant and the development of the LESSWATT project were illustrated with particular reference to the B2 action and the floating tests of the LESSDRONE.



A new permanent collaboration agreement has been signed - the fifth - with the LIFE project MCUBO (Modeling, Measurement and Improvement of the water management environmental impact in the food industry - LIFE15 ENV/ES/000379) whose aim is to reduce the environmental impact associated with water management in the three sub-sectors that consume more water in the food industry (meat, canned vegetables and juices).
