| Abstract: | Seawater desalination, in rapid development, is an effective measure to alleviate the freshwater scarcity crisis in China. However, there is a significant concern about the water quality and cost of the desalination systems, but little attention has been paid to the quantitative evaluation of water resource efficiency. Based on the ISO water footprint principle, this work delineated the system boundary of sea water desalination, performed the inventory analysis of the production phase of seawater desalination systems, and proposed a method for water footprint quantification and evaluation of typical seawater desalination systems. Evaluation results revealed that the scarcity footprint of the multi-effect distillation(MED) technology was 3~4 times higher than that of the reverse osmosis(RO) technology, and the power consumption was the determining factor for the water footprint of all the technologies. The degradation water footprint of RO technology was much lower than that of MED. Overall, the RO technology showed more excellent water resource efficiency than the MED among the studied cases. This work revealed the consumption and pollution of water resources in seawater desalination production via the water footprint analysis. It may help develop the sea water desalination improve water resource efficiency, reduce energy consumption and eliminate water pollution, and provide support for scientific development and utilization of seawater. |
