Powdered Activated Carbon

 Introduction to Powdered Activated Carbon:

Powdered activated carbon is produced from sawdust and other raw materials using the zinc chloride method.  It has a developed mesoporous structure, large adsorption capacity, and fast filtration characteristics.  Wooden powdered activated carbon is mainly suitable for decolorization, extraction, deodorization, and impurity removal of various amino acid industries, refined sugar decolorization, monosodium glutamate industry, glucose industry, starch sugar industry, chemical additives, dye intermediates, food additives, pharmaceutical preparations, and other high pigment solutions.

 Application of powdered activated carbon :

Beverage and food industry: Powdered activated carbon is used for purification treatment of beverages and foods, such as cola, juice, alcohol, etc.  It can remove impurities, pigments, and odors, ensuring the purity and high quality of products.

Water treatment: Powdered activated carbon is widely used in water treatment, which can effectively remove organic matter, chlorine gas, odors, pigments, and heavy metals from water, and improve the quality of drinking water.  In addition, it is also used for sewage treatment and tap water treatment, with excellent adsorption and decolorization ability.

Air purification: Powdered activated carbon can remove harmful gases, odors, and volatile organic compounds from indoor and outdoor air, improving air quality.

Waste treatment: In industrial waste treatment, powdered activated carbon can effectively treat pollutants in wastewater and reduce negative impacts on the environment.

Pharmaceutical field: Powdered activated carbon has various applications in the pharmaceutical field, including medical adsorbents, detoxifiers, intestinal cleansers, etc.  It is used to treat poisoning, kidney disease, and intestinal diseases.  In addition, it is also used for decolorization, refining, and removal of heat sources for various injectable drugs.

Chemical industry: Powdered activated carbon is used in the chemical industry for decolorization and purification of various high pigment solutions, such as sugars, oils, chemical additives, fuel intermediates, pharmaceutical preparations, etc.

Characteristics of powdered activated carbon:

Appearance: Powder activated carbon appears as a black powder, delicate and uniform.

Large specific surface area: The surface of powdered activated carbon is covered with a large number of micropores and mesopores, which provide a huge adsorption area.  The surface area per gram of activated carbon is usually 500~1500m ², allowing it to effectively adsorb various harmful substances.

High purity: Powder activated carbon has low impurity content and high purity, ensuring its good adsorption performance.

Strong adsorption performance: Powdered activated carbon has extremely strong adsorption capacity and can adsorb various harmful substances such as heavy metal ions, organic matter, pigments, etc.  Its adsorption performance mainly depends on its pore structure and surface chemical properties.  The high adsorption efficiency of powdered activated carbon is mainly reflected in its large contact area, which can fully contact the substances that need to be adsorbed.

Good chemical stability: Powdered activated carbon can maintain stable adsorption performance in various environments and will not lose its adsorption effect due to environmental changes.

High temperature resistance: Powdered activated carbon has good high temperature resistance and can maintain stable adsorption performance in high temperature environments.

 Precautions for powder activated carbon :

1. Powdered activated carbon belongs to porous adsorbents, so it is necessary to prevent water immersion during transportation, storage, and use.  After water immersion, a large amount of water fills the active voids, rendering them ineffective.

2. To prevent tarry substances from being used during the process, it is necessary to prohibit the introduction of such materials into the activated carbon bed, to avoid blocking the pores of the activated carbon and causing it to lose its adsorption function.

Packaging and Storage of Powdered Activated Carbon: 

Packaged in 25kg bags (woven bag packaging with a polyethylene plastic film lining). 

During storage, ensure protection against moisture, sunlight, and water. Try to prevent packaging damage as much as possible to avoid affecting adsorption.
