Fluoride Dosing Calculator

Calculate fluoride chemical feed rate based on target level, current level, flow rate, and chemical type/purity.

CDC/PHS recommended optimal: 0.7 mg/L for community water systems.
mg/L
Natural fluoride level in source water before treatment.
mg/L
Treatment plant flow rate.
MGD
