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 back-washing to eliminate
accumulated suspended matter and to re-grade the filter bed.
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
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.

12 x 40 is an excellent filtration medium with excellent adsorptive properties. Used for the removal
of taste and odors, chlorine, etc. Periodic back-washing is required in down-flow 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.
