Described is a chemical feeder (E;) having a housing (10) with a base member (12) and upwardly extending side walls (14) that define a cavity (8) for containing solid chemical material, e.g., calcium hypochlorite. A hollow chamber (20) is located within the cavity and seated on the base member (12). An annular collection zone (48) is created by the side walls (18) of the chamber (20) spaced apart from the side walls (14) of the housing (10). There is an inlet (40) for supplying dissolving liquid into the hollow chamber (20) and up through a grid (22) and an outlet (34) for removing a liquid solution of the dissolved chemical material from the collection zone (4).

Une chambre (20) placée dans la cavité repose sur la base (12) et ses parois latérales (18), distantes de celles (14) de l'enceinte (10), délimitent une zone collectrice annulaire (4). Une amenée (40) introduit dans la chambre (20) le solvant liquide qui monte à travers une grille (22) puis ressort par un orifice (34) pour permettre de soutirer de la zone collectrice (4) une solution liquide du produit chimique dissous.
