A. Hi,

For boron removal there are some methods.

E.g., there are selective ion exchange resins (such as Purolite S-108 or Amberlite IRA 743).

Ion exchange is the method of choice, when you don't have to remove other components. Otherwise membrane processes like Nanofiltration or reverse osmosis might be helpful, too.

Q. Hi, Wolfgang Neubrand.

May I know the effectiveness of using Nanofiltration? Will Nanofiltration at 0.2 micron nominal size work for boron removal? How good is it?

Thank you

A. Boron removal can be achieved by commercially available ion exchange resins with the N-Methylglucamine functional group (a couple of products I know of Amberlite XE-243 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.

A. Seplite LSC800 resin can remove the boron.
