Fluoride is fed into the water system using either a solution feed system or a(n):

Fluoride is typically fed into the water system using various methods to ensure proper dosage and distribution within the water supply. A dry feed system is one of the effective methods for introducing fluoride. In this system, the fluoride compound, usually in granular form, is added to the water through a mechanical feeder that can control the flow rate and ensure consistent dosing.

The choice of a dry feed system allows for ease of handling and dosing, especially in larger systems where precision is crucial to meet regulatory limits for fluoride content in drinking water. Moreover, this method can often be more economical than liquid systems, as it reduces the risk of spillage and contamination.

In contrast, solutions or liquid forms of fluoride may require different handling and dosing equipment, which can complicate the process. The preference for dry feed systems in many applications is linked to their effectiveness and the ability to maintain target fluoride concentrations efficiently.
