Granular Activated Carbon - for Taste and Odor Removal-1 CUBIC FOOT

$89.00

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 waste. 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 taste characteristics.

Features and Accessories

Product Features

Activated Carbon requires only periodic backwashing to eliminate accumulated suspended matter into re-grade the filter bed. Activated Carbon has an extremely high capacity but must be replaced when the filter bed loses capacity for removal of taste and odor. Activated 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 desirable to have the greatest possible surface area in the smallest practical volume. This is necessary 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 square meters per gram. This results in high efficiency and greater 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 tastes, odor and color loads.
  • Activated Carbon will import a high "polish" to the filtered water.
