A new steelmaking facility will be built in a desert region for the production of 1.500.000 t/y of steel billets. Severe problems of water scarcity greatly affect the cooling water auxiliary plant. Following the traditional sizing criteria the need of more than 650 m3/h of raw water consumption was estimated, as peak hourly value. To meet the target of maximum 250 m3/h of available water in site, a not-conventional approach was necessary. Cooling equipment with low water consumption and internal recycle of treated water drains has been adopted. Conversely high investment cost and electrical energy consumption will be suffered. The solution finally results also economically interesting, especially thanks to the water chemical conditioning saving and could be applicable in other industrial realities. An overview is provided.
