Activated carbon filter material - an industrial tool for efficient adsorption and purification

Activated carbon filter material is a filter material with high-quality activated carbon as the main functional component. With its extremely developed pore structure and huge specific surface area (usually 500-1500㎡/g), it can efficiently absorb organic pollutants, strange-colored and odorous substances and some heavy metal ions in gases or liquids. Activated carbon filter materials are widely used in air purification, water treatment, waste gas treatment, food decolorization, pharmaceutical solvent recovery and other fields.

1. Adsorption principle and classification of activated carbon

The adsorption of activated carbon is divided into two mechanisms: physical adsorption and chemical adsorption. Classified by form: granular activated carbon (GAC) is suitable for large flow treatment; powdered activated carbon (PAC) is directly added to the water treatment process; activated carbon fiber (ACF) has a larger specific surface area and faster adsorption speed; honeycomb activated carbon has small ventilation resistance and is a mainstream product for VOCs control.

2. Core advantages of activated carbon filter material

Large adsorption capacity: The pore inner surface area of 1 gram of high-quality activated carbon is equivalent to the area of a standard football field.

Wide range of application: It can adsorb volatile organic compounds (VOCs) such as benzene, aldehydes, ketones, esters, and hydrocarbons, as well as residual chlorine, odor pigments, etc.

Multiple specifications can be customized: It can be made into various forms such as granules, powders, fibers, honeycombs, etc., and can be combined with non-woven fabrics, glass fiber and other substrates to make a variety of filtration products.

3. Precautions for use

Avoid high temperature and high humidity environments; saturated activated carbon should be replaced or regenerated in time; operators should wear dust masks and gloves.
