Abstract
There are various ions in seawater. In order to use seawater as the drinking water, some elements are to be concentrated and other elements are to be removed. To obtain these characteristics using seawater, it is necessary to adjust seawater quality. Because calcium and magnesium are especially healthful to human bodies, it is required to concentrate these elements. In this study, the technology to obtain the hard water from seawater by electerodialysis was investigated. After concentrated water was produced using nanofiltration membranes, sodium chloride was eliminated from the concentrated water by electrodialysis. The hard water production from seawater was successfully achieved using electrodialysis in this study.
