Tertiary filtration is often used to meet low level phosphorus effluent requirements. Chemicals may also be added during this tertiary step to precipitate soluble phosphorus and improve the removal of total phosphorus.
Read how the City of Barnesville, Georgia, was able to achieve an 85% reduction in TP and produce an effluent quality of < 0.3 mg/L of phosphorus, 50% below the allowable limit, using the Forty-X Disc Filter from Evoqua (part of Xylem) and a additional chemical phosphorus removal stage.
