New Resins for Ion Exchange Applications and a Process for Their Sustainable Regeneration

Abstract

The report is concerned with the design and synthesis of a mixed bead resin for high salt level desalination. The resin allows for the simultaneous exchange of both anions and cations, within the same polymer. This improves the efficiency of desalination at seawater levels. A novel process for sustainable and low energy desalination for brackish water has already been achieved via ion exchange resins as explained below. The advance in resin technology improves a novel membrane process with closed–cycle regeneration of the resin. It is a superior alternative to reverse osmosis.
