ACTIVATED CARBON, BITUMINOUS COAL 20 x 50 (FOR TASTE and ODOR REMOVAL) ACARB-AW2050 is a smaller particle carbon that offers increased surface area and longer contact times. This improves the removal of taste and odors, chlorine, etc. Offsetting this is the fact that using a finer carbon will increase pressure drop through the filter unit which must be taken into consideration when selecting a tank size. This 20 x 50 Mesh product is Acid Washed.

ACTIVATED CARBON, COCONUT SHELL 12 x 30
(FOR CHLORINE REMOVAL)

Coconut shell carbon, because it is comprised of predominantly microporous structures, is a superior preforming product for the removal of chlorine, chlorinated solvents and VOCs. It is also harder and can stand up to more backwashing than bituminous coal based carbon. Its drawbacks lie in its higher price and its inability to absorb heavier organics. 12 x 30 Mesh.

MACROCARB - 8 x 30 - ACTIVATED CARBON

A granular activated carbon manufactured from specially selected grades of eucalyptus wood. The material is manufactured under stringently controlled conditions by steam activation to produce a porous adsorbent with a highly developed internal surface area. Optimum organic removal, ideal for tannin removal.

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. Ac ti vat ed 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. Ac ti vat ed Carbon may be used in either domestic or industrial applications using pressurized filter vessels.

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.

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
