Selecting the appropriate activated alumina product is essential for achieving optimal performance in various industrial applications, from water treatment to gas drying. Understanding the key specifications and performance factors of activated alumina allows users to make informed decisions that align with their specific needs. NINGBO INNO PHARMCHEM CO.,LTD. provides a comprehensive range of activated alumina products and the expertise to guide your selection process.

One of the most critical specifications for activated alumina is its surface area. Typically measured in square meters per gram (m²/g), a higher surface area generally indicates a greater capacity for adsorption. For applications like fluoride and arsenic removal from water, or as a desiccant, a high surface area, often exceeding 300 m²/g, is highly desirable. This large surface area provides more sites for contaminant ions or water molecules to attach to.

Closely related to surface area is pore volume, measured in milliliters per gram (ml/g). This metric reflects the internal pore space within the activated alumina beads, which dictates how much material can be adsorbed. A well-developed pore structure, with a balance of macropores, mesopores, and micropores, is crucial for efficient mass transfer and high adsorption capacity. The specific pore volume of our activated alumina products is carefully controlled during manufacturing to ensure optimal performance for targeted applications.

Adsorption capacity, often expressed as static water absorption percentage or the amount of contaminant adsorbed per unit mass of adsorbent, is a direct measure of performance. For instance, the static absorption of water for our activated alumina can range from 50-70%. Similarly, its capacity for fluoride and arsenic removal is a key performance indicator. NINGBO INNO PHARMCHEM CO.,LTD. provides detailed data on the adsorption capacities of our products to assist clients.

Other important factors include bulk density, which affects the amount of material that can be packed into a given volume, and attrition loss, which indicates the material's resistance to physical breakdown during handling and operation. Low attrition loss is vital for applications where the activated alumina is subjected to fluid flow or mechanical stress, preventing fines from entering the system. Crushing strength is another indicator of the bead's robustness.

When considering activated alumina for specific applications such as activated alumina for arsenic removal or as an activated alumina desiccant, it's important to match the product's specifications with the operational conditions. Factors like pH, temperature, flow rate, and the concentration of contaminants all play a role. NINGBO INNO PHARMCHEM CO.,LTD. offers various grades of activated alumina, including specific formulations optimized for different tasks. Our technical team is available to help you select the activated alumina water absorption or contaminant removal product that best suits your process requirements.
