A
simple, clay filter incorporating the microbiological inhibiting
properties of colloidal silver is providing clean drinking water to
families throughout the developing world. Called a Filtrón, the
device can be made by enterprising local potters and sold
inexpensively
to people in rural areas to eliminate the microorganisms often present
in water used for drinking. The Filtrón is a ceramic filter shaped
like a flowerpot that is saturated with an industrial concentration of
colloidal silver. The filters can be press-molded, formed by hand, or
turned on a potter's wheel before being fired in a brick kiln. Made
from a mix of clay and sawdust, the filters block the larger
water-borne particles while the colloidal silver inactivates bacteria
small enough to get through the filter's tiny holes. The device has
been proven 98 to 100% effective in the laboratory in
eliminating bacteria and bacterial indicators, though education and
proper use are vital to replicating these results in household use.
