A water treatment device for purifying small quantities of non-potable water for drinking purposes. The device includes: a primary container, a secondary product container, and a cylindrical filter cartridge. The primary container is filled with untreated water, and brought into contact with a disinfecting agent. The filter cartridge is then attached to the primary container and the secondary container is attached to an outlet port of the filter cartridge, the entire arrangement is then inverted to allow water to flow from the primary container into the inlet port of the filter cartridge. A physicochemical time switch is installed near the inlet port of the filter cartridge and blocks the flow of water from the primary container into the filtering elements until an appropriate amount of time has lapsed for the disinfecting agent to effectively disinfect the water. The physicochemical time switch is either a water dissolvable barrier or an expandable compartment filled with hydrophilic polymeric crystals. The filter cartridge includes anion exchange resins, filtering media for removing suspended impurities, and activated carbon for removing organic impurities and chlorine residue.

[ What I claim is:] [1.]1. An emergency water treatment device, comprising:a) a primary container for receiving untreated water, and a disinfecting agent contained therein,b) a secondary container for receiving treated and filtered water,c) a filter cartridge with a filter element contained therein with the cartridge positioned between the primary and secondary container which filters the water flowing from the primary container to the secondary container,d) a physicochemical time switch which blocks the flow of water from the primary container to the filter element for a period of time which coincides with a disinfecting period wherein the disinfecting period is a time period for disinfecting the untreated water within the primary container with the disinfecting agent.
