Project Overview

To search constantly for new solutions to increase the internal reuse of process waters is the renewed commitment requested by the WaVE project from all thermal plants with a view to reducing their water requirements. The Santa Barbara Plant (392 MW) in Italy uses water mainly from the operation of evaporative cooling towers. The availability of water is, however, reduced, depending on the level of the overlying basin of the San Cipriano dam, and the restitution of water to …

To search constantly for new solutions to increase the internal reuse of process waters is the renewed commitment requested by the WaVE project from all thermal plants with a view to reducing their water requirements. The Santa Barbara Plant (392 MW) in Italy uses water mainly from the operation of evaporative cooling towers. The availability of water is, however, reduced, depending on the level of the overlying basin of the San Cipriano dam, and the restitution of water to the valley water body is often limited by the need to contain its thermal rise, especially in periods of low flow. The plant has managed to change the functioning of the cooling towers by means of new treatment of the evaporative cycle water and an advanced system of checking and regulation capable of monitoring and controlling the chemical-physical parameters of the recirculated water in real time. These interventions have facilitated an increase in the number of concentration cycles of the evaporative towers, leading to a 15% reduction of make-up water, as well as the flowrate of the water discharged. Similar initiatives are planned for the Pietrafitta (Italy) and Ventanilla (Peru) plants. The Mah_n plant operates on the island of Minorca, in the Balearic Islands, an area classified as of high water stress due to the scarce availability of the natural resource, together with high demographic pressure. The recent installation on the plant of nitrogen oxide (NOx) abatement systems, requiring water to operate, could have increased the impact. The solution adopted, therefore, was that of utilizing the wastewater coming from the nearby municipal wastewater treatment plant to feed the emission abatement system, in this way avoiding withdrawal from scarce water sources and recovering wastewater that would otherwise have been discharged into the sea.
