Shell-based Activated Carbon

FAQ

• What should I do if the effectiveness of Guokel charcoal decreases after some time?

  This is a normal phenomenon. When the pores of activated carbon become filled with pollutants, it reaches "adsorption saturation" and loses its adsorption capacity. It should be replaced promptly with new activated carbon; we recommend replacing it every 1 to 2 months. If used for air purification, you can try exposing the activated carbon to sunlight for 3 to 5 hours to evaporate absorbed water molecules, allowing reuse for 6 to 10 months.

• What should be noted during storage and transportation?

  Coconut shell activated carbon should be stored in a cool, dry place to prevent moisture absorption and adsorption of other substances from the air. During transportation, avoid mixing with hard materials, and do not subject it to strong vibrations, trampling, or throwing, as this may break the carbon particles and affect performance. Water immersion is strictly prohibited, as water can fill the pores of the activated carbon, causing loss of adsorption capacity.

• Should activated carbon be cleaned before use?

  It is recommended to clean it to remove dust, but the method should be carefully considered. When used for water treatment, avoid rinsing directly with fresh tap water, as chlorine in the water may be adsorbed into the pores of the activated carbon, affecting its performance later. For air purification, surface dust can be removed using a vacuum cleaner.

• How can you determine if activated carbon has become ineffective?

  You can assess it by observing changes in the treated water quality. During the initial use, frequently monitor the effluent quality; when performance noticeably declines, it indicates that the activated carbon has reached adsorption saturation and needs to be replaced.

• Should fire prevention be considered when storing and using activated carbon?

  Yes. Activated carbon is a combustible material, so it should be kept away from direct contact with sources of ignition during storage or transportation. Safety precautions are also necessary during regeneration; after regeneration, the temperature must be allowed to drop to a safe range before exposing the material to air to prevent spontaneous combustion.

• What substances can affect the performance of activated carbon?

  Tar-like viscous substances should be prevented from entering the activated carbon bed, as they may clog the pores and impair the adsorption capacity. If the gas contains tar-like materials, a tar removal unit should be installed prior to the activated carbon bed for pre-treatment.
