Calgon Carbon - Model SGL 8x30 -Granular Activated Carbon

SGL carbon is made from selected grades of bituminous coal combined with suitable binders to give superior hardness and long life. Produced under rigidly controlled conditions by high temperature steam activation, SGL is a high density carbon with large pore volume and moderately high surface area. Its pore structure has been carefully designed for the adsorption of both high and low molecular weight impurities from solutions.

• Bituminous-based raw material
• High density
• Coal is pulverized and re-agglomerated with suitable binder

• Provides higher hardness relative to other raw materials reducing the generation of fines and product losses during backwashing.
• Pore structure provides a wider range of contaminant removal capabilities relative to other starting materials.
• The carbon wets readily and does not float, thus minimizing loss during backwash operations.
• Creates optimal transport paths for faster adsorption.
• Generates the hardness and abrasion resistance required for thermal reactivation and minimizing generation of fines in operations requiring backwashing.

The advantages and economies of using SGL carbon have found wide acceptance in the chemical and food process industries for the decolorization and purification of numerous aqueous and organic liquids. Typical of these are the purification of glycols, soda ash and caustic liquors, sugar solutions, pharmaceuticals, and plasticizers.

Economy of Column Operation. The use of highly active Calgon Carbon Corporation granular carbons in fixed or pulse bed systems provides the ultimate in countercurrent efficiency and simplicity of operation. The columns eliminate the need for slurry tanks, filter presses, and multiple treatment which is necessary with powdered carbon. A properly designed system offers these benefits when compared to powdered carbon:

• A clean, continuous operation.
• Efficient utilization of the activated carbon
  • more impurities adsorbed per pound of carbon.
• Less equipment - less floor space.
• Lower carbon dosage - lower costs.
• Improved product quality - better colors - higher purity

Reactivation

In those applications where the volume of carbon in service is large, farther savings can be realized through the reactivation of SGL for continued use in repeated cycles. Partial reactivation can sometimes be accomplished by chemical treatment without removing the carbon from the columns. In other cases, it is more satisfactory to use high temperature processing equipment such as the Herreshoff multiple-hearth furnace or direct-fired rotary kilns.
