Chemical Phosphorus Removal
Metal-Salt Precipitation with High-Rate Clarification
Chemical phosphorus removal uses iron or aluminum salts to precipitate phosphorus, followed by plate settler clarification for reliable low-phosphorus effluent.
Chemical Phosphorus Removal
Chemical phosphorus removal is the most widely used method for meeting phosphorus limits. Dosing ferric chloride, alum, or similar coagulants converts soluble phosphorus into insoluble metal-phosphate precipitates.
The success of the process depends on efficient separation of these precipitates. Plate settlers excel here, capturing the light flocs at high loading rates and returning them as a thickened chemical sludge.
Compared with expanding conventional clarifiers, adding a plate settler stage allows plants to implement or intensify chemical phosphorus removal without major civil works.
