Effect of activated carbon mesh size on flow rate and pressure drop

The mesh size of activated carbon affects its adsorption performance, flow rate, and pressure drop of the carbon bed.

Activated carbons with low mesh size (larger particles) have lower surface area and are suitable for gas treatment and air purification because they provide lower airflow resistance and higher flow rate.

Activated carbons with medium mesh size balance surface area and pore structure and are widely used in water treatment and wastewater treatment. They can effectively remove organic matter and impurities while maintaining appropriate flow rate and pressure drop.

Activated carbons with high mesh size (smaller particles) have larger surface area and higher adsorption capacity and are suitable for applications such as fine chemicals and pharmaceuticals that require high adsorption efficiency, but their flow rate is lower and the pressure drop of the carbon bed is larger.

Selecting the right mesh size of activated carbon can optimize its adsorption effect, flow rate, and pressure drop in specific applications.
