Iodine disinfection dispenser

A device for providing a disinfectant carried by a supply of water flowing through a conduit, comprising:

• a sealed container having a reservoir and a chamber below the reservoir in intercommunication therewith, the reservoir holding a quantity of iodine crystals lying in a bed in the bottom portion of the reservoir and being of a predetermined size sufficient to hold a quantity of water proportional to the maximum flow rate attainable through the conduit and such that a maximum concentration of 120 parts per million (milligrams per liter) is obtainable as an outflow from the container when the supply of water is at least above freezing, the chamber below the reservoir containing a bed of filter material;
• inlet means for the connection with the water supply and opening into the chamber, and outlet means opening from the reservoir above the iodine crystals, the inlet means comprising a first tube having an outlet portion opening into the chamber and the outlet means comprising a second tube opening into the reservoir above the bed of iodine crystals said second tube projecting into the reservoir and closed at the end thereof, and carrying a plurality of slots adjacent the closed end for the passage of water, the slots being of a size to prevent the passage of crystalline iodine therethrough, whereby all said water portion passes through the filter material and between the iodine crystals.
