The 1-1.5mm size is one of the most popular specifications in the market. Engineers and buyers alike unanimously choose it for applications ranging from compressed air drying towers to drinking water defluorination equipment. So, what are the performance advantages of 1-1.5mm activated alumina?
Key Advantages:
High Specific Surface Area: The 1-1.5mm particle size ensures a large specific surface area per unit volume, providing ample space for adsorbing water molecules, fluoride ions, etc., guaranteeing high adsorption capacity.
Optimized Pressure Drop: If the particles are too small, the resistance to fluid (gas or liquid) passing through the bed will be too high, increasing energy consumption. The 1-1.5mm size creates an ideal porous bed structure, ensuring smooth fluid flow, reducing system energy consumption, and ensuring sufficient contact time with the medium.
Superior Mechanical Strength and Durability: The 1-1.5mm activated alumina particles possess extremely high compressive strength and wear resistance, are not easily broken or pulverized, thus greatly extending service life and reducing replacement frequency and downtime costs.
Superior Deep Drying Capacity: Strong hydrophilic properties easily lower the air dew point to -40℃ or even lower, effectively protecting downstream equipment and production processes from water damage. Its rigid particle characteristics further resist the "slippage" impact of liquid water, which is unmatched by many desiccants.
Highly efficient selective adsorption: The 1-1.5mm filter has a high selective adsorption capacity for fluoride ions, which can efficiently reduce the fluoride content in water to below the safety standard (<1.0 mg/L), ensuring water quality and operational efficiency.
Wide range of applications:
Compressed air and industrial gas drying: Serves as the core packing material in desiccant dryers, providing an ultra-dry air source.
Drinking water defluoridation: Widely used in water plants, communities, and household water purification systems in high-fluoride areas, ensuring public drinking water health.
Catalyst carrier: Serves as a stable catalyst carrier in petrochemical, fertilizer production, and other fields, supporting active ingredients.
Other adsorption applications: Used for transformer oil regeneration, phosphorus and arsenic removal from industrial wastewater, etc.
Choosing 1-1.5mm activated alumina will also give you:
Longer service life: High strength means less wear and tear, and with appropriate regeneration processes (thermal purging or chemical regeneration), it can be recycled multiple times.
Lower overall cost: Although the unit price is slightly higher than larger sizes, its longer lifespan, higher efficiency, and lower pressure drop result in energy savings, making its total lifespan cost more advantageous.
More stable operating performance: Uniform particle size distribution avoids bed channeling and short-circuiting, ensuring the stability and reliability of the treatment effect.
