METHOD OF REMOVING BORON IN SEAWATER ADOPTING CRYSTALLIZATION PROCESS

摘要

PURPOSE: A method for eliminating boron from seawater is provided to cost-effectively implement boron using a reverse osmosis process without an expensive ion-exchanging resin. CONSTITUTION: A reverse osmosis process is implemented with respect to seawater using a front reverse osmosis film(1). The pH of concentrated water, which does not permeate through the front osmosis film, is adjusted in order to implement a pre-crystallization process and a filtering process. In the filtering process, a reverse osmosis process is implemented with respect to filtering water under the filtering process using a rear reverse osmosis film(2). Permeated water through the front and the rear reverse osmosis films is collected.
