METHOD FOR REMOVING BORON FROM SEAWATER USING REVERSE-OSMOSIS MEMBRANES

摘要

The present invention relates to a method for removing boron from seawater by using reverse-osmosis membranes, which is characterized in that it comprises: adding, to the seawater, a composition that comprises at least one metal with at least one anti-fouling/dispersant agent, and a second stage in which an alkalinizing agent is added in order to achieve a pH of between 8-9.5. There may also be a third stage in which the seawater fluoride content is increased after the second stage, or a third stage in which an alcohol of high molecular weight is added to the water.
