ABSTRACT:
An imparter to impart silver to a water system wherein air is drawn into a receiver container when water is withdrawn from the receiver container into a storage container. The water is withdrawn from the receiver container through an opening that is disposed below the level of water in the receiver container and its lower end is beneath a maximum water elevation in the storage container and above some lower elevation therein. The imparter is placed in the opening. It has a dimension of thickness defined by a pair of end walls which partially define a cavity in the imparter body. There are perforations in both of the end walls to permit water to flow through the cavity and thereby through a bed of silver imparting material inside the cavity. This material has the inherent property of transferring silver into the water as a consequence of contact therewith. Air vent means extends from end wall to end wall of the body to admit air to the receiver container along an entry path separate from a discharge path that goes through the cavity. The air vent means is so proportioned, disposed and arranged that air enters the receiver container via the air entry path in preference to the discharge path and water exits from the receiver container via the discharge path in preference to the entry path.
