A dry chemical pellet dispensing apparatus particularly adaptable for treatment of well water with chlorine pellets or like water purification tablets. A downwardly open pellet container is secured to a pellet flow regulator housing, which discharges pellets onto the surface of a metering plate. The discharge housing has baffles to regulate pellet flow. The metering plate has arrays of compartments for holding individual pellets. Select compartments are open and select compartments are closed. Open compartments can each receive a pellet. The pellet is moved in the open compartment upon rotation of the metering wheel to a location over a drop opening leading to a discharge tube which drops the pellet into the well. The speed of rotation of the metering wheel and the density of open compartments determines the dosage rate of pellets administered to the well. The metering wheel is mounted in a guide plate, which has first and second positions with respect to a drive motor for imparting first and second rotational speeds to the metering wheel.
