Abstract The existing methods for seawater freezing desalination include direct crystal suspension freezing and indirect progressive contact freezing (IPCF). However, freeze desalination is rarely used because of the low rates of desalination and freshwater production along with the relatively high treatment costs. In this study, we evaluated a new freeze desalination method using supercooled water dynamic ice making. The proposed method had a theoretical energy consumption of only 58% of that needed for IPCF. With gravity filtration separation of the produced ice–water mixture for 20 min or centrifugal dehydration for 1 min, a 0.5% salt content standard for freshwater and a 60% freshwater yield were attained. In addition, the method produced ice crystals with minimal impurities, after brine attached to the surface was removed through centrifugal dehydration, a 0.05% salt content standard for drinking water was achieved.

过冷水动力制冰海水淡化实验研究

摘要 现有的海水冷冻脱盐方法包括直接晶体悬浮冷冻和间接渐进接触冷冻（IPCF）。然而，冷冻海水淡化很少使用，因为海水淡化和淡水生产率低，处理成本相对较高。在这项研究中，我们评估了一种使用过冷水动态制冰的新冷冻海水淡化方法。所提出的方法的理论能耗仅为 IPCF 所需能耗的 58%。通过对产生的冰水混合物进行重力过滤分离 20 分钟或离心脱水 1 分钟，淡水盐含量标准为 0.5%，淡水产率达到 60%。此外，该方法产生的冰晶杂质极少，
