Abstract: Water is passed through a cartridge containing a bactericide 38, e.g. iodine crystals and then after sufficient delay in diffusers 46 and spring chamber 44 for the treatment to be completed through an agent 40, e.g. active carbon which will be sufficient to remove the bactericide. The neutralizing effect of the agent is designed to be exhausted before the bactericide so that a visual olefactory or taste indication that the cartridge needs attention is given. The water may be filtered by material 10 or pretreated with chemicals. Arrangements of cartridges are given in figures not shown, including valve means to prevent leakage of bactericide.
