Features

High Mechanical Properties; Calgon Carbon's reagglomerated coal-based granular activated carbons have several properties which provide superior performance in a wide range of applications; Produced in the United States from a pulverized blend of high quality, domestically mined bituminous coals resulting in a consistent, high quality product.; Carbon granules are uniformly activated through the whole granule, not just the outside, resulting in excellent adsorption properties and constant adsorption kinetics.; The reagglomerated structure ensures proper wetting while also eliminating floating material.; High mechanical strength relative to other raw materials, thereby reducing the generation of fines during backwashing and hydraulic transport.; Carbon bed segregation is retained after repeated backwashing, ensuring the adsorption profile remains unchanged and therefore maximizing the bed life.; Reagglomerated with a high abrasion resistance, which provides excellent reactivation performance.; High density carbon resulting in a greater adsorption capacity per unit volume.

Absorbent

Applicable Processes

Aquaculture, Brewing, Drinking Water Treatment, Groundwater Treatment, Sewage Treatment, Water Reclamation

Safety

Wet activated carbon can deplete oxygen from air in enclosed spaces. If use in an enclosed space is required, procedures for work in an oxygen deficient environment should be followed.

Industrial

Process

This activated carbon is manufactured from select grades of bituminous coal through a process known as reagglomeration to produce a durable granular product capable of withstanding the abrasion associated with repeated backwashing, air scouring, hydraulic transport, and thermal reactivation. The raw coal is mined and subsequently manufactured into GAC in the United States to ensure the highest quality and consistency in the finished product. Activation is carefully controlled as measured by the iodine number for effective adsorption of a broad range of high and low molecular weight organic contaminants. The higher density of FILTRASORB brand GAC results in a product with both a greater adsorptive capacity on a volume basis and a longer life through multiple reactivation cycles.

Custom Reactivation

Municipal drinking water utilities can extend the life of their FILTRASORB granular activated carbon while lowering their operating costs through participation in Calgon Carbon's Custom Municipal Reactivation (CMR) program. After a granular activated carbon's adsorptive capacity has been exhausted, it can be returned to Calgon Carbon for thermal reactiva-tion (upon carbon acceptance approval). In the reactivation process, the spent activated carbon is heated to a high temperature in furnaces devoid of oxygen, using steam as a selective oxidant. The high temperature reaction with steam serves to restore the adsorptive capacity of the activated carbon.; The CMR program ensures that each customer receives their own GAC back after reactivation. The benefits of using a custom reactivated GAC versus a virgin carbon are several, including: a) economic, as reactivated GAC costs less than virgin GAC, and b) environmental, as use of reactivated GAC conserves natural resources and reduces CO2 emissions compared to the manufacture of virgin GAC. Another benefit of reactivating and reusing spent granular activated carbon is the ability for customers to ensure for themselves a reliable supply of GAC when needed, as the spent/ reactivated carbon represents a renewable resource. Finally, through reactivation, the costs and long-term liability associated with disposal of spent GAC are eliminated.; The combination of high mechanical strength and the dense granular structure of FILTRASORB brand GAC, a product of both the bituminous coal starting material and the reagglomeration manufacturing process, results in a GAC ideal for reactivation, with excellent adsorptive performance and low losses.
