摘要： A fluoridation apparatus is disclosed that is adapted to be attached to a water faucet for introducing minute concentrations of fluoride into the drinking water. The fluoridation apparatus comprises a main chamber and an adjacent reservoir chamber. The main chamber has an inlet in its upper portion for coupling to a water faucet and an outlet in its lowermost portion. By-pass and return conduits are provided for by-passing a portion of the water flowing through the main chamber into the reservoir chamber. The by-pass conduit includes a restriction formed therein, the flow through which is laminar. A quantity of fluoride compound is disposed within the reservoir of the adjacent chamber to saturate the water in the reservoir with fluoride ions. A proportionalizer is positioned within the main chamber forming a barrier between the inlet and outlet with the barrier having a plurality of relatively small conduits extending therethrough. The plurality of conduits divide the total flow into many separate flows to create a laminar flow condition in the proportionalizer. During operation (when the faucet water is turned on), a portion of the water passing through the main chamber is by-passed through the reservoir chamber to be saturated with fluoride particles. As the water flow continues, the fluoride saturated water is returned to the main chamber for mixing with the main stream of water passing through the proportionalizer.
