Advantages of Granular Activated Carbon

 

Activated Carbon Pellets For Air Filter

Eliminates Pollutants and Contaminants

The water is exposed to pollutants and contaminants that make it undrinkable and unsafe for human consumption. The dirt, impurities and contaminants must be extracted from the water bodies for safe usage. The best way to get rid of these pollutants is with activated carbon. The granular activated carbon eliminates the VOC (volatile organic compound), pollutants and other dirt from the water.

Granular Activated Carbon Water Filtration

Durability

The granular activated carbon has a large surface area that allows for the absorption of more contaminants from the water. Some carbon can be harmful to humans if used for extended periods. However, the coconut shell granular activated carbon is completely safe and highly durable.

Bamboo Activated Carbon

Prevent Water Pressure From Dropping

When the filter media gets in the way of water, the water pressure can be reduced, for this carbon is the primary reason the water pressure drops. However, with the granular activated carbon, the carbon blocks are loose, allowing the water to pass without interruption. So there is no problem with water pressure reduction.

How Is Pellet Activated Carbon Manufacturing

 

The production process of extruded activated carbon involves the selection and treatment of raw materials, key steps such as carbonization and activation, ensuring the final product has a well-developed pore structure and adsorption performance.

 
Step 1: Raw Material Grinding:

The first step involves grinding the raw material coal to a certain fineness (generally above 95% passing through 180 mesh). Raw materials suitable for production include anthracite, coconut shell powder, wood, etc. The commonly used material is taixi coal from Ningxia.

 
Step 2: Binder Formulation

After preparing the raw materials, a certain amount of binder (commonly tar) and water are added. When using the catalytic activation method, a certain amount of catalyst is simultaneously added at a certain temperature for a specified duration. The treated hard coal is mixed with a certain proportion of tar, ensuring uniformity for molding.

 
Step 3: Granulation or Molding

Once the added binder and water fully infiltrate, permeate, and disperse evenly with the coal powder, the mixture is pressed into charcoal rods using a molding machine under a specific pressure and with a certain diameter extrusion die. The formed columnar charcoal is then dried under specific conditions to maintain a specific moisture content, usually around 10%, to form a robust charcoal structure.

 
Step 4: Carbonization

The dried charcoal is placed in a carbonization furnace, and slowly heated to control the carbonization speed and temperature, reaching the conditions for chemical reactions. This process causes the gradual thermal decomposition and volatilization of organic substances in the charcoal, forming a structure with numerous pores and high carbon concentration.

 
Step 5: Activation

After carbonization, the raw material undergoes activation to increase its pore structure and surface area. Activation develops more micropores and mesoporous structures, enhancing the adsorption capacity of activated carbon.

 
Step 6: Quality Inspection and Packaging

The produced pelletized activated carbon undergoes quality inspection to ensure compliance with relevant standards and quality requirements. After rigorous inspection, it can be packaged in custom-branded bags or other weight bags for customer use.

FAQ

 

Q: What are the Dimensions of Activated Carbon Pellets?

A: The dimensions of pellet activated carbon usually vary depending on the application. Different scenarios and requirements may have different specifications and size choices. The typical diameter range can vary from a few millimeters to several centimeters, usually between 0.9 mm and 8 mm, with 4 mm being the most commonly used.

Q: What is the difference between activated carbon and granular activated carbon?

A: Granular activated carbon filters are made using carbon that has been ground up and is held together loosely inside a cartridge or other container. On the other hand, carbon block filters are made by grinding activated carbon into a fine powder.

Q: What are the properties of granular activated carbon?

A: Granular activated carbon (GAC) has a greater ability to absorb gases and vapors because there is more room between its particles for gas to pass through. However, GAC has a smaller internal surface area, necessitating a delicate balance between its adsorption capacity and grain size.

Q: Does granular activated carbon remove PFAS?

A: For the utility that undertook this pilot study and their desired treatment goals, granular activated carbon (GAC) was found to be an effective treatment technology for PFAS removal.

Q: Is granular activated carbon safe to use?

A: GAC treatment is similar to that of home water filters and is generally considered safe to use. Treated water and air are sampled and analyzed regularly to ensure that the carbon continues to adequately sorb contaminants.

Q: How do you make granular activated carbon?

A: Granular activated carbon is made from raw organic materials that are high in carbon, such as coconut shells, coal, peat and wood. Heat is used to activate the surface area of the carbon, removing certain chemicals dissolved in water as they pass through a filter containing granular activated carbon.
