| titleOfInvention | Treatment of toxicant-impregnated filter cake |
| abstract | A filter cake formed of a glass precursor material and impregnated with a normally leachable toxicant can be heated, preferably with at least one other glass precursor material, at a sufficiently high temperature to form a molten composition which solidifies, upon cooling, to form a glass. The normally leachable toxicant becomes fixed within the glass rendering it substantially more non-leachable for a more environmentally sound means for disposal, e.g., by landfill techniques. The process can be used to treat the arsenic sulfide-impregnated filter cake derived from the manufacture of food grade phosphoric acid. |
