Abstract: A water chlorinator device for use in a water recirculating conduit system having a water pump connected therein. The chlorinator device comprises a housing having a chlorine-containing chamber vented to atmosphere. A perforated support member is provided for supporting one or more solid chlorine tablets. Projections support a lower one of the tablets elevated from a top surface of said support member. The water supply compartment is provided under the support member and is fed pressurized water from the conduit system downstream of the pump. The water entering the supply compartment exits through orifices formed in the support member whereby to form a turbulent, chlorine dissolving, water cushion above a top support surface of the support member. The water cushion is formed of a plurality of pressurized water jets to dissolve the lower one of the solid chlorine tablets to form chlorine-treated water.
