Fluoride is added to water in three practical delivery forms used in water treatment: a dry chemical, a liquid solution, or a slurry. The dry form means feeding a powdered fluoride compound directly into the treatment stream, which can be convenient for certain feed systems and storage setups. The solution form uses fluoride dissolved in water as a liquid feed, often chosen for ease of metering and consistent dosing. The slurry form is a suspension of solid fluoride in water, used when a stable, pre-mixed dose is advantageous. Each method has different handling and equipment needs, but all serve the same purpose of achieving the target fluoride level in the finished water. Gaseous fluoride isn’t used for public water fluoridation, and paste, gel, foam, or tablets are tied to dental applications rather than plant dosing.
