| 摘要 |
The present invention describes a chemical feeder (2) that supplies treating agents, e.g., calcium hypochlorite, to a liquid stream, e.g., an aqueous stream. The chemical feeder (2) is operated in a substantially flooded condition to provide a useful and safe pressure feeder, and optionally uses cyclonic flow to be relatively self-cleaning. One or more tablet canisters (34) are utilized within the substantially flooded interior (62) of the chemical feeder, and expose the lowermost tablets to the turbulent flow outside of the tablet canister. A substantially uniform chemical distribution rate over tablet life is provided by the chemical feeder.
