Whether your needs are for advanced water treatment, efficient paper sizing, or vibrant textile dyeing, selecting the appropriate grade and supplier is paramount. Here’s a guide for buyers to consider when sourcing aluminum sulfate.

Purity and Specifications: The most critical factor when sourcing aluminum sulfate is its purity, often specified by the percentage of aluminum oxide (Al2O3) content, typically ranging from 15% to 17% for industrial grades. For specific applications like drinking water treatment, low iron content is essential, hence the preference for non-ferric or low-ferric grades. Buyers should also pay close attention to specifications regarding water insolubles, arsenic, and heavy metals, as these can impact performance and compliance, especially in sensitive applications like potable water or food-grade products.

Form and Appearance: Aluminum sulfate is commonly available in several forms: flake, granular, and powder. The choice of form often depends on the handling capabilities and specific process requirements of the user. Flakes are typically easier to dissolve, while granular forms may offer better flowability. Powders are also available but can be more prone to dusting. Ensuring the correct physical form is vital for ease of use and efficient dissolution in your application, whether it’s for water treatment systems or batch processes.

Packaging and Handling: Industrial chemicals require appropriate packaging to maintain quality and ensure safety during transport and storage. Aluminum sulfate is commonly supplied in 25kg, 50kg, or 1000kg PP woven bags. Bulk shipments, such as 20'GP containers, often carry between 25-28 tons, sometimes without pallets depending on handling requirements. Buyers should confirm packaging details and inquire about storage recommendations to preserve product integrity.

Application-Specific Considerations: For water treatment, aluminum sulfate acts as a flocculant, and its effectiveness is paramount. In the paper industry, it serves as a sizing agent to improve paper quality. For textiles, it's used as a mordant to enhance dye fixation. Understanding these distinct roles will help buyers select the grade that best meets their application's specific needs. For instance, a paper mill might prioritize consistency in sizing performance, while a water treatment plant would focus on the flocculation efficiency and purity for safe water.
