Point-Of-Use
Drinking Water
Filtration Systems
The below explanation refers only to how solid carbon block filtration
systems work.
 Do
not confuse carbon with charcoal, as they are so completely
different that there is no comparison.
Point-Of-Use Drinking Water Filtration Systems are
designed to provide the consumer the utmost in performance, safety, and
convenience.
A replaceable triple-action carbon filter was
formulated of materials approved by the U. S. Food and Drug Administration,
which has been found to provide the highest quality drinking water without
removing the healthful minerals.
The material contained in these filters combine
mechanical filtration, electrokinetic adsorption, and physical adsorption to
provide the most efficient contaminant removal possible.
-
Water enters the filter through a graded density
pre-filter, made from a special blend of refined cotton, which acquires a
positive molecular charge in a moving stream of water.
Since most colloidal and bacterial contaminants exhibit a negative charge
in solution, the media fibers electrokinetically adsorb charged colloidal
particles too small for removal by mechanical straining.
The media combines the technology of mechanical straining, for the removal
and retention of solid and semi-solid contaminants that can cause
premature clogging, and electrokinetic adsorption for the reduction of
colloidal contaminants down to the sub-micron range.
-
Then the water passes through the highly compacted
solid carbon block filter media which is a blend of selected activated
carbons and polyethylenes.
The compacted solid carbon block filter media is designed to mechanically
filter particles down to sub-micron size, including microscopic organisms,
asbestos, turbidity, and particulate matter.
By micro-straining the water, the consumer is assured that only the
cleanest, clearest water is delivered to the point-of-use.
The components of the carbon block section of the filter are insoluble,
and while themselves chemically inactive, some of the material exert a
catalytic effect, inducing molecular changes in the many chemicals
contained within the water.
It is through this chemical reaction and physical adsorption that
chlorine, certain pesticides, volatile organic chemicals, and dissolved
lead are removed.
The solid carbon block filters are exceptionally uniform and do not
channel or bypass as conventional granular activated carbon (GAC) filters
are known to do.
Conventional GAC filters become incubators of bacteria, encouraging
growth; however, the densely compacted filters eliminate this problem
because there is no room for growth in the tightly compacted carbon.
-
Finally, the water passes through a pharmaceutical
grade post-filter which provides integral strength to the carbon block
section and prevents material degradation of the filter.
The threaded polypropylene end caps seal the carbon block and assure the
integrity of the seal between the filter and the housing.
This unique formulation of solid carbon block water filters not only remove
substances that cause water to taste and/or smell bad, they also reduce a
wide range of unhealthy contaminants such as...
- Asbestos
- Cysts
- Lead
- Certain Pesticides
- Trihalomethanes
- V olatile Organic Compounds
The length of use of these solid carbon block filters
varies in proportion to the amount of water used, and the type and level of
impurities in the water being processed.
As a general guideline the filter should be replaced when the one of the
following occurs...
-
The recommended unit's rated capacity is reached - Each
model is different.
-
Once per year - For standard use, this is most common.
-
The water flow rate diminishes - This means the filter
is saturated.
- Unpleasant tastes and odors - This means the filter is saturated.
