METHODS FOR REDUCING BORON CONCENTRATION IN HIGH SALINITY LIQUID USING COMBINED REVERSE OSMOSIS AND ION EXCHANGE

摘要

Methods are provided for increasing the recovery rate in systems (Fig.2) for treating high salinity boron-containing liquids, such as seawater, to reduce salinity and boron concentration. The methods involve applying multi-pass reverse osmosis (1, 2), combined with partial ion exchange processing utilizing a boron specific resin, for reducing the capital and operating costs of desalination systems.
