Abstract
The Bureau of Mines, as part of its mission to effect pollution abatement, conducted research to develop a technique for dewatering phosphate clay waste from disposal ponds. Phosphate clay waste was dewatered from 11.8 pct to greater than 20 pct solids using 0.53 Lb of polyethylene oxide (peo) per ton of dry solids. Dewatering was accomplished by mixing the clay waste with peo and treating the resulting flocs on a static screen followed by further treatment on a rotating trommel screen. Discharge from the trommel screen, when placed in a column 23 inches in diameter and 11 feet in height, continued to dewater to greater than 28 pct solids in 90 days.
