CPG - Model LF 12x40 -Acid Washed Granular Activated Carbon
CPG LF is a granular activated carbon with a low acid soluble iron content that is designed for the purification and decolorization of many aqueous and organic liquids. It can be used efficiently in either fixed or moving beds. The particle size of 12 x 40 mesh has been selected to give a high rate of adsorption and low resistance to flow with liquors of medium viscosity. CPG LF is produced with virtually no fines or dust. CPG LF 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, this carbon provides high surface area, large pore volume, high density and a pore structure optimal for the adsorption of color bodies and odor molecules from solution.

- Produces a strongly adsorbing pore structure optimal for the adsorption of color bodies and odor molecules.
- Reduces iron and ash levels so that product does not leach in acidic solutions.
- Cleaner, more efficient operation than with powdered carbons. Lowers product cost, improves product quality. Requires less equipment to operate than with powdered carbon.
One of the most common uses of CPG& LF is in solutions of low pH such as corn syrup. Since the carbon has been acid washed, the constituents of CPG& LF will not be leached into the acidic solution. Furthermore, the high adsorption capacity of CPG in fixed or moving beds permits continuous decolorizing cycles, after which the carbon can be thermally regenerated for repeated use. The advantages and economic benefit of CPG LF are also evident when it is used in the purification of acid solutions such as muriatic and adipic.
Economy of column operation
The use of highly active Calgon Carbon granular carbons in fixed or moving beds provides the ultimate in countercurrent efficiency and simplicity of operation.
A properly designed system offers:
- A cleaner, continuous operation
- More 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, plus odor removal
