A new method to restore the water quality level through the use of electric boats

In recent years, sustainability has become a focal point in the city development policies leading to the definition of smart city paradigm. A smart city paradigm was conceived with the aim to integrate technology development with different functions/component like sustainable mobility, energy management and water quality. In this paper we propose a novel water sanitization method based on the combination of the classical bioremediation approach with the use of electric boat. The proposed boat must be equipped with echo sounding, G.P.S. sensor and suitable injector. Furthermore it is provided of medium size energy storage systems and power generation from renewable source in order to ensure a completely environmentally friendly mode of operation. The use of this vessel allows to reduce the operating cost of sanitization procedure and permit to integrate a technique for the improvement of the quality of the water in the contest of the Smart City. In fact the proposed boat can interact with the energy management strategy of the city and can participate to vehicle grid policies. A preliminary implementation of the proposed sanitization procedure have been realized at the Rome EUR pond sited in the south area of city. Suitable microorganisms were distributed on three equally spaced points of the basin by meas of a prototype electric boat. The same points were used to monitor the some parameters used to validate the proposed strategy. Obtained results show that the quality of water has been restored to the optimal value after the treatment of bioremediation.
