ABSTRACT:
Chemical treatment device, i.e., a chlorinator for use in a swimming pool filtration and circulation system having a skimmer system with a water intake from the pool, a filter for receiving and filtering water intaken, and a pump for returning filtered water to the pool. The device has a vessel of synthetic material with a compartment for treatment chemical, and is provided with an array of break-opens at different levels for opening through from exteriorly of the vessel into the compartment. The device includes an arrangement for locating the vessel to receive flow of water entering the skimmer causing flow to be exposed to the chemical for dissolving it. Interior walls of the compartment diverge downwardly to prevent bridging of the chemical within the compartment. The compartment has a drain for discharging treated water into the skimmer system. Discharging may also take place through the break-opens.
