The Berkey® Secret
Have you ever wondered how Berkey® purification systems remove pathogenic bacteria, cysts
and parasites while extracting chemicals including herbicides, pesticides, organic solvents, VOCs, detergents, cloudiness,
silt, sediment, foul tastes and odors? Or, how Berkey® systems are able to reduce heavy
metals such as cadmium, chromium, copper, lead, mercury, aluminum and other dangerous heavy metals without removing the healthful
and beneficial minerals that your body needs?
And finally, how is this system is able to remove red food coloring
from water without removing the beneficial minerals your body needs?
The unique Berkey®
design combines the age-old process of micro-porous filtration coupled with modern state-of-the-art technology and the highest
quality materials to bring you the finest water purification system available anywhere. The micro-pores within the self-sterilizing
and re-cleanable Black Berkey® purification elements are so small that pathogenic bacteria
are simply not able to pass through them.
The media within the
elements remove contaminants by a surface phenomenon known as “adsorption” which results from the molecular attraction
of substances to the surface of the media. The exclusive purification elements are also impregnated with proprietary “absorbing”
media that promote IONIC “absorption” of pollutants within the micro-porous elements.
Another reason Berkey® systems are so effective in removing contaminants from water
is the extremely long “contact period”. Other filtration systems rely on water pressure that forces water
molecules through the filter elements at 60-90 PSI. These water molecules come into contact with the filter media for
a mere fraction of a second. By comparison water molecules, passing through the “Tortuous Path” structure
of the Black Berkey® purification elements, are drawn gently by gravity and stay in contact
with the media for a long period of time. This allows the filter media to be more efficient in capturing contaminates.
For example, if you were to hurl 100 steel ball bearings at a large magnet, some would stick but most would bounce off.
However, if you were to walk over and gently place the ball bearings on the magnet most, if not all, would adhere to the magnet.
Berkey® systems fully utilize this principle.
This advanced technology was developed, refined, and proven through years of diligent, investigative research and
testing performed by water purification specialists, researchers and engineers. The flow rate or time of exposure through
the exclusive Black Berkey® purification elements has been calculated to yield the greatest volume removal
of toxic chemicals and pathogenic bacteria found in nature and caused by pollution from industry and agriculture.
