ABSTRACT:
In the electric arc furnace production of elemental phosphorus, cold phossy water is segregated from hot phossy water. The cold phossy water is discharged to a lined pond wherein solids settle to form a clarified cold water which is recycled for cooling and washing purposes. The hot phossy water is passed through a lamellar settler wherein phosphorus and solids are separated as a sludge to form a clarified hot water. The clarified hot water, without requiring additional heat, is recycled for process use. Phosphorus is recovered from the sludge to reduce to a minimum the amount of phosphorus discharged with dirt from the hot phossy water to the pond.
