Boron removal 

+

We are interested in cost effective removal of boron from water at levels of around 5 ppm. Does anyone have any advice or information?

Boron removal can be achieved by commercially available ion exchange resins with the N-Methylglucamine functional group. Couple of products I know of Amberlite XE-243 (May have a new name now) and Purolite S-108. Though a weak base anion backbone, resin is regenerated with sulfuric acid, and boric acid is recovered as a by product by crystallization. Hope this helps.
