The Development of a Fluorine Removal Agent Using Incinerated Ash (II)

Abstract

The compounds of aluminum phosphate are used to remove the fluorine compounds from wastewater. The fluorine removal agent using the ash of sewage sludge and the municipal waste in addition to sulfuric acid were investigated. The removal agent showed high removal performance, and the fluorine concentration of the treated water reached below 0.1 mg/L, and the noticeable elution of the harmful metals from the ashes were not found in this experiment.
