Removal of Borates from Waste water

Hi... I see that the subject has been brought up already. We use a compound consisting mainly of potassium fluoroborate and other borates as soldering flux. The MSDS of this products says that the product should be treated with lime before letting off into water bodies. To my knowledge.. this will precipitate calcium fluoride but what about the borates?. Will it precipitate fluoroborate as well? If not.. how can I get rid of the borates in my waste water

Hi, Mark. Yes, this is a popular subject. In fact we have many threads on Boron in Wastewater listed on our FAQ page. Good luck.
