DISCUSSION ON COMPREHENSIVE UTILIZATION OF CONCENTRATED BRINE FROM SEAWATER DESALINATION
Seawater desalination is one of the most important ways to settle the problem of water resources shortage in China. The direct drain of concentrated brine produced in the desalination would destruct the eco-environments to some degree. Furthermore it makes the comprehensive utilization of chemical resource more effective because of the high and stable concentration of the concentrated seawater. The comprehensive utilization processes of concentrated seawater including the process based on the traditional brine pond, the method of salt production by electrodialysis, the technology of synthetically extracting the chemicals from the brine and the RO-electrodialysis integrated membrane process are introduced. The advantages and disadvantages as well as the feasibility of those technologies application in China are discussed in detail. Some proposals about the development of concentrated seawater utilization in China also are put forward.
