Powdered Activated Carbon

Powdered Activated Carbon (PAC) is a high performance absorbent engineered to remove harmful contaminants in the air, gas, and liquid phases. How to choose the right activated carbon powder? Learn more now!

Powdered activated carbon (PAC) material is finer material. PAC is made up of crushed or ground carbon particles, 95–100% of which will pass through a designated mesh sieve. The ASTM classifies particles passing through an 80-mesh sieve (0.177 mm) and smaller as PAC. According to the raw material, it can be divided into wood and coal based activated carbon.

Wood activated carbon powder VS Coal activated carbon powder

Raw material difference

activated carbon material

Coal-based powdered activated carbon uses anthracite as raw material, which will produce more pore structures during processing. Therefore, coal-based powdered activated carbon is a porous carbon with a relatively developed pore structure. It has low bulk density, large specific surface area, and can Adsorb macromolecular pigments and other substances and impurities in aqueous solutions.

activated carbon raw material

Wood powdered activated carbon uses sawdust, peach shells, fruit shells, etc. as raw materials. The processed activated carbon products are relatively moderate in terms of metals and chemicals, and have a wider range of applications. The application of wood powdered activated carbon can not only be used in In water treatment, it can also be used in food, sugar, pharmaceuticals, etc. Therefore, the price and demand of wood-based powdered activated carbon are higher than that of coal-based powdered activated carbon.


Because coal-based powdered activated carbon is made from coal, it has more impurities, higher chemical composition, and a slightly higher ash content than wood-based powdered activated carbon. Therefore, it cannot meet food specifications. This is why coal-based powdered activated carbon cannot be used in medicine or food industry. This type of powdered activated carbon is suitable for use in chemical sewage treatment, industrial wastewater treatment, domestic sewage treatment, etc.

How to make powdered activated carbon?

Powder Activated Carbon is made from high-quality wood chips, coconut shells, and coal as raw materials. Powder activated carbon has low processing lost. It is mainly used in liquid-phase adsorption, mixed with the liquid, and after adsorption, remove by sedimentation and filtration.

Is Powdered Activated Carbon safe?

Powdered activated carbon, in its genuine state, is not a hazardous material or hazardous waste. Therefore, applicable governmental regulations for waste disposal would apply. Used powdered activated carbon may become classified as hazardous waste depending upon the application.

The advantages of powder activated carbon

  • High quality sawdust or coal powder as raw materials
  • Large surface area with fast filtration capacity
  • PH can adjust as customer demand
  • Ash is controlled within 5% with excellent purity

Where is powdered activated carbon used?


Powdered activated carbon (PAC) has a high surface area, and Methylene blue (M.L.) value has excellent decolorizing properties, we have a wide range of activated carbon products specifically designed for color removal applications, including food, chemical, and pharmaceutical purification.

  • Medicine liquid color removal
  • Refined industrial solvent filtration
  • Food and beverage ( sugar, MSG, juice decolorization)
  • Water treatment (drinking water and sewage purification)

Coal activated carbon powder application

activated carbon for water and gas

Coal Powder activated carbon is grinded into suitable powder size by qualified activated carbon. Due to the advantages of the powder state, it can diffuse and contact with the treated media completely, which will be beneficial to the increase of the absorptive efficiency, the series carbon is mainly used for the purification of drinking water, deep treatment of industrial water, the decolorized and refining treatment of solvents, etc.

Application type:

  • Drinking water treatment
  • Wastewater treatment
  • Groundwater remediation
  • Process water treatment
  • Aquarium water treatment
  • Waste incineration gas treatment

Wood activated carbon powder application

Wood powder activated carbon is non-toxic, without taste and it has the appearance of a fine black powder. Offering a sizable surface area, and robust adsorption abilities, it is perfectly suited to water clarifying and purifying within the production of sugars, pharmaceuticals, beverages, and also wines.


  • Glucose decolorization, maltose decolorization, citric acid decolorization, cystine decolorization, oil decolorization, chemical products, and macromolecule decolorization.
  • Water treatment, such as life water, industry water, purified water, and drink.
  • Food additives.
  • Pharmaceutical Industry.
  • MSG, chemical, beverage, and other decolorization.

How to identify the quanlity of activated carbon?

Performance-based testing is the best method to select the most efficient PAC for your application. In different applications, indicators are also needed to determine activated carbon products with specific requirements. Therefore, the index parameters are very important in the production process of activated carbon.

  • Iodine value
  • Methylene blue value
  • Molasses value
  • Pore Diameter
  • Surface Area
  • Density
  • Ash Content
  • Mesh

Performance-based testing during the product selection process is the best way to ensure that you provide the cleanest, most drinkable water and decolorization application in the food and beverage industry.

How to choose activated carbon powder?

Choosing the right activated carbon powder takes much more than just considering the price difference. Zhulin offer activated carbon of different types and grades and to choose the right activated carbon you must take into account several factors. You must analyze the performance characteristics in light of specific uses.

At ZhulinCarbon, we offer the most effective and safe water solutions for our clients, such as Foxconn (domestic sewage treatment), Bright Dairy, and so on, which has certificated our stable and good performance of the activated carbons.
