A new and useful approach to cleaning raw water or other raw liquid is provided.
A metered amount of stabilized hydrogen peroxide is added to the raw water or other
liquid, to clean the raw water or other liquid. In one particularly useful embodiment
of the present invention, a portable drinking device is designed so that a metered
amount of stabilized hydrogen peroxide can be added to a portable container of
liquid, to clean raw water or other liquid in the portable container. Thus, a hiker,
military person, or other person who may have to depend on his/her environment
for sustenance, and who may not have an available water source other than raw water,
has a simple and efficient way of using virtually any available body of raw water
as a source, and cleaning the raw water, to provide the person with a portable
source of clean water.
