Activated Carbon
Resins, Media & Chemicals
Activated Carbons
Granular Activated Carbon constitutes an excellent filtration media,
having a high density with a balanced pore-structure for more
efficient absorption.
One of the most common applications for Activated Carbon is the
removal of the undesirable taste present in many chlorinated water
supplies. This taste is the result of the formation of chlorophenols,
often present in raw waters which contained phenols and were
subsequently treated with chlorine. These phenols are usually the
product of industrial wastes. Even 0.1 ppm of chlorophenols can
result in an undesirable taste. Activated Carbon has for many years
been successful in the absorption of orthochlorophenol and the
removal of free chlorine from water supplies. The end product is
clean, fresh water with no objectionable tastes.
Activated Carbon requires only periodic backwashing to eliminate
accumulated suspended matter and to re-grade the filter bed.
Activated Carbon has an extremely high capacity but must be
replaced when the filter bed loses the capacity for removal of
taste and odor.
To obtain maximum efficiency
of the activated carbon in the
absorption process, it is best to
have the greatest possible surface
area in the smallest practical
volume. This is because the rate
of absorption is proportional to the amount of surface area of the
absorbing medium media. Activated Carbon has a surface area
of 800 sq. meters per gram. This results in high efficiency and
system economy.
When considering Activated Carbon for taste, odor and color
removal applications, it is necessary that the influent be
relatively free of iron for maximum service life. It is also
necessary that the influent be free from oil and other
suspended matter, as these constituents may reduce
the overall efficiency of the activated carbon.
Activated Carbons
Advantages:
• The large surface area
results in an exceptionally
high capacity and efficiency.
Activated Carbon is very hard
so losses due to attrition are
kept to a minimum
• Activated Carbon is an
outstanding material for
applications requiring taste,
odor and color removal
from water with suspended
matter present. This product
can be used for filtering
waters having a wide range
of pH levels.
• Activated Carbon has a very
high carbon-low ash content.
Service rates of 5 gpm/sq.
ft. are practical for ordinary
taste, odor and color loads
• Activated Carbon will import
a high “polish” to the
filtered water

12 x 40 is an excellent filtration medium with excellent adsorptive properties. Used for the removal of
taste and odors, chlorine, etc. Periodic backwashing is required in downflow filters. Maximum carbon
life is usually three years.

JACOBI ACTIVATED CARBON, COCONUT SHELL 12 X 40 (FOR CHLORINE REMOVAL)
AquaSorb® CS is a high activity granular activated carbon manufactured by steam activation from select
coconut shell charcoal. Its enhanced microporosity makes it particularly well suited for the removal
of low molecular weight organic compounds and their chlorinated by-products such as chloroform
and other trihalomethanes (THM's). It is also ideally suited for the removal of oxidizing agents such as
chlorine and ozone from process water. An important feature of this material is its superior mechanical
hardness and the extensive dedusting during its manufacture that ensures an exceptionally clean
activated carbon product.

JACOBI ACTIVATED CATALYTIC CARBON, COCONUT SHELL 12 X 40
AquaSorb® CX-MCA is a catalytic, high activity granular activated carbon manufactured by steam
activation of select coconut shell charcoal. The catalytic activity of this activated carbon makes it highly
effective for the removal of chloramines and hydrogen sulfide from potable water. Its large micropore
volume makes it particularly well suited for the removal of low molecular weight organic compounds
and their chlorinated by-products such as chloroform and other trihalomethanes (THMs). An important
feature of this material is its superior mechanical hardness and the extensive dedusting during its
manufacture ensures an exceptionally clean activated carbon product.
