Abstract
A process is described for the solidification of concentrated boric acid waste solutions. The waste solution must have a boric acid concentration greater than 30% by weight. Sodium metasilicate is added to the boric acid waste solution and is mixed; a dry, hard product is formed. The process is not hindered by the presence of up to 40% dewatered bead resins.
