Understanding The Patented KDF®55 Redox Media
The
KDF®55 redox media is a patented, high purity alloy of copper and zinc. It
eliminates contaminants from water by utilizing the principle of
electrochemical oxidation-reduction, known as redox potential. Redox is
simply the principle of opposites at work. Some substances are positively
charged and are attracted to the negative charge of the zinc. Others are
negatively charged and attracted to the positive charge of the copper.
KDF®55 media uses the redox principle in the presence of dissolved oxygen to
effectively remove chlorine, chlorinated hydrocarbons, hydrogen sulfide,
iron, and metals like lead, arsenic, aluminum, mercury, and cadmium from
water.
As water
containing dissolved substances enters a bed of high purity copper-zinc
granules, copper becomes a cathode and zinc an anode. The tiny space between
each granule becomes an electrolytic cell, with the water and its contents
acting as the electrolyte.
As
contaminants and oxygen pass through, some minerals (like heavy metals)
plate out on the surface of the granules. Other contaminants react causing
zinc oxides, sulfates, hydroxides and copper hydroxides to form in
controlled amounts. These compounds are carried into the filtered water and
along with ozone created in the process, provide hostile conditions for
viruses, algae, fungi and bacteria.
The
copper and zinc chelates produced by the system are not only harmless in the
amounts produced, they are actually healthful nutrients to the human body
and one of the reasons the manufacturer of our
shower filters
and water
purifiers, has chosen to use KDF filters.
KDF
Process Media are generally used in place of, or in conjunction with,
granular activated carbon (GAC) water filters. KDF Process Media extend the
life of GAC while protecting the carbon bed against fouling by bacterial
growth.
INDEPENDENT LABS CONFIRM SUPERIOR PERFORMANCE
Independent laboratory tests confirm that KDF®55 is one of the best tools
for improving drinking and bathing water naturally and economically.
Compared to carbon-only units, KDF®55 lasts far longer, doesn't permit
bacterial growth and removes a much wider range of inorganic matter (e.g.
heavy metals). Compared to reverse-osmosis, KDF®55 is less expensive, wastes
no water, does not require membrane replacement, works at most water
temperatures and pressures and removes chlorine. Compared to ultraviolet
lights, KDF®55 works in cloudy water, doesn't require bulb replacement or
electricity and removes inorganics. Compared to ozone, KDF®55 provides a
residual effect to keep bacteria from growing in water, does not require
electricity and costs less.
