Abstract
In resource-starved Japan, sea water resources have attracted attention until now. However, there is no utilization example technology except for a salt and water. It is apprehensive about resource reservation becoming difficult in the near future. Then, it is required to investigate the integrated utilization technology of sea water and brine-concentrate resources in detail. In this report, the following five contents were mainly investigated. (1) Evaluation of concentrated brine produced by desalination process. (2) Re-consideration of the resources which dissolved in sea water. (3) Reappraisal of the production economy of the resources which dissolved in sea water and brine-concentrate and investigation of the high-value-added technology of the chemical compounds originating in the resources which dissolved in sea water. (4) Combination with salt and bitten treatment processes. (5) Proposal of integrated utilization process for sea water and brine-concentrate resources.
