ABSTRACT:
A method and apparatus for the purification of water in emergency situations is provided, comprising a manually operated pump having a discharge port connected to a plurality of series-connected treatment filters. Each filter is chosen for its ability to perform a desired purification function in a preferred sequence which enhances the performance of the subsequent filter in the series. The filters are designed to accept water from a contaminated source, thereafter removing particulate matter, organic impurities and inorganic impurities, and finally physically filtering out bacteria and other organisms larger than 0.20 microns in size to deliver potable water from the outlet port of the final filter. Preferably, all components are mounted in a suitable portable enclosure for ease of storing and for transporting the unit to a water source in an emergency situation.
