What
kind of filter is the Solid Carbon Block filter?
Aren't
They All The
Same?
The Solid
Carbon Block filter blended of selected activated carbons to adsorb
chlorine and filter a wide range of organic materials. Considered to be the most
effective method for removing chlorine, asbestos, cysts, turbidity, lead, TTHMs,
and many pesticides volatile organic chemicals. The carbon is compacted into a
dense structure causing every molecule of water to be forced through microscopic
pores of carbon, effectively removing these pollutants. The solid carbon block
filter is a replaceable cartridge designed so that it can be easily changed when
a certain quantity of water is processed or the water flow rate decreases due to
filtration of particulate matter. Some additional advantages of the Solid
Carbon Block Filter are: does not waste water; no electricity required; does
not remove essential trace mineral that are beneficial to good health; does not
add salt or silver to the water; provides fresh, delicious drinking water.
Solid Carbon Block Filters:
This technology has combined the incredible
adsorption capability of carbon discussed previously with the ability of a solid
brick of material to selectively strain out particles from water forced through
it. The density of the brick determines how finely the water is cleaned. The
better brands of this type of filter have a three part filter and are designed
to prevent any possibility of "bypass" due to high pressure failure.
The following list of features are what combine to
create the type of filter that will remove the widest range of possible
contaminants in the drinking water:
- Mechanical straining:
the block of carbon mechanically strains out dirt, sediment, rust, algae,
cryptosporidia, asbestos and particulate matter. This is all accomplished by
water pressure so no electricity is required -- such a filter even works on
a simple hand pump in emergencies!
- Chemical bonding: As
explained earlier, activated carbon bonds to thousands of chemicals. In
fact, carbon will bond to most chemicals known to man! When water is forced
through the solid carbon block, it is forced to slow down and increase the
contact time with the carbon, allowing the carbon bonding to take place to
reduce certain chemical pollutants like toxics, pesticides, THM's, chlorine,
bad tastes, odors, etc.
- Health-providing
trace minerals like dissolved calcium and magnesium do not bond to carbon
and are allowed to pass through, thereby retaining the health quality and
good taste of the water.
- Heavy
metals like lead are adsorbed (or collected) by the carbon.
- Prevention of bacterial
growth: Bacteria are strained out and remain on the outside of the carbon
block. Therefore, because of the density and lack of oxygen and space inside
the block, bacteria cannot breed in the medium and come out in the finished
water.
- Convenient: This type of
system provides healthier filtered water on demand so there is no storage,
nor running out at inconvenient times, no ordering bottles or picking
bottles up from the store.
- Inexpensive: This type
of filter is a replaceable, self-clogging cartridge that lasts eight to 12
months (dependent on amount of sediment and dirt). The cartridge is designed
to be replaced in minutes at home by the homeowner, just like screwing in a
new light bulb. The cost of the units are relatively inexpensive -- over a
ten-year period, the cost of the unit plus maintenance works out to a mere
sixty bucks a year!! The cost of the water itself is from four to 8 cents
per gallon. The units themselves are generally very easy to install and are
designed to be a 45 minute installation for the handy homeowner or plumber.
They can also be connected with refrigerators that have automatic icemakers
and water dispensers so that all the water that a household consumes is
filtered!
- The
only drawback to solid carbon block systems is they will not remove nitrates
or sulfides (byproducts of agricultural fertilization), and in these cases
RO technology can take care of the problem. Nitrates and sulfides are found
in relatively few areas however, so most consumers do not need to worry
about them.
