Boron removal from seawater using FILMTECTM high rejection SWRO membranes Original Research Article

This paper gives a quick introduction to the boron problem and its relevance in seawater desalination. It then covers the chemistry of boron in water and provides data for the pH-dependant rejection of boron with various membrane types. Field data on boron rejection from a high recovery seawater desalination plant using FILMTEC seawater reverse osmosis (SWRO) membranes is presented thereafter. Four characteristic design concepts that have been used to achieve low boron limits are discussed from an economic and technical point of view.
