 · The boron has conventionally been added to the glass particle stream during the particle deposition step. However, when the required amount of fluorine exceeds about 0.6 wt. % (0.2% DELTA ), the fluorine cannot be incorporated into the preform during the particle deposition step since fluorine in the reactant vapor stream reacts with water in the air to form HF.

The removal of boron from wastewater has to be considered on a case‐by‐case basis because no boron compound is known to be precipitated quantitatively. Based on an industrial case, many methods were tested for the treatment of wastewater containing 50 g L −1 of sulfuric acid and 0.7 g L −1 of boron, and a well‐adapted precipitation process consisting of the neutralization of boric ...
