Ferric Salt Phosphorus Removal Agent
Ferric chloride or ferric sulfate solution dosed for chemical phosphorus precipitation in municipal and industrial wastewater treatment. Iron(III) ions react with orthophosphate to form insoluble ferric phosphate (FePO4) precipitate, achieving effluent total phosphorus levels below 0.5 mg/L. Used in pre-precipitation, simultaneous precipitation, or post-precipitation configurations.
