Boron removal from chrome plating effluent

I would like to know the cost effective methods for the removal of boron from chrome plating bath, boron conc is 25mg/L , it should be reduced to 2mg/L. could you suggest the suitable resins for the removal using ion-exchanger, I also would like to know that whether any co-precipitation method is available for boron removal of this concentration.if any other alternative cost effective method is available please mention.......

Thanking u

The electrolytic catalytic precipitation will help you to solve the problem. This works by oxidizing the metal by overdosing it with oxygen in the electrolytic chamber.
