Boron removal from wastewater?
Anyone out there have a process (or an idea!) for removing boron from wastewater generated from Alodine process? The boron from sodium fluorborate which is present in our chemistry. Our local limit for discharge is 5 ppm and the concentrations in our raw wastewater are around 20 to 30 ppm.

There are boron-selective ion exchange resins. I don't have the technical information readily available as I write this but I will get it together for anyone who needs to know more.
You can also put in a total recycle deionization system (non-selective cation and anion resins) and return the water back to the process. The fluoborates will be removed along with all the other ions in the process. Canister rental and off-site regeneration is preferred to on-site regeneration when you have a discharge limitation. You get rid of the discharge problem by letting someone else do the regeneration. Unfortunately this also costs more.

Will a method work to remove levels of boron from 1.2 mg/L to <0.2 mg/L (our discharge criteria)?Jamie K [last name deleted for privacy by Editor]
We have up to 35 ppm in our waste water. Shall like to know more about a system. flow rate is 6m3/hr.

I am interested in boron removal from water, in particular from produced water. I am studying the feasibility of this by a electrochemical means.G Pieruz
