For businesses in sectors ranging from water treatment to paper manufacturing and textiles, aluminum sulfate is a critical raw material. Navigating the market to find a reliable supplier that offers quality products at competitive prices is a key challenge for procurement managers and R&D scientists. This guide, from NINGBO INNO PHARMCHEM CO.,LTD., a leading manufacturer and supplier, outlines essential considerations for B2B buyers when looking to purchase aluminum sulfate.

Understanding the specifications of aluminum sulfate is the first step. Key parameters include the Aluminum Oxide (Al2O3) content, which typically ranges from 15% to 17% for industrial grades. The Iron (Fe) content is another critical factor; low iron content (often specified as ≤0.005% for Fe) is essential for applications where color is a concern, such as in the production of bright white paper or certain dyeing processes. Other important specifications might include water insolubility and pH value. Buyers should also consider the physical form—whether granular, powder, or liquid—and particle size distribution, as these can impact handling and dissolution rates. When you buy aluminum sulfate, ensure it aligns with your specific application requirements.

The applications of aluminum sulfate are diverse. Its primary use is as a coagulant and flocculant in water purification, effectively removing impurities from potable water and treating industrial wastewater. In the paper industry, it serves as a sizing agent, enhancing paper quality and printability. The textile industry utilizes it as a mordant for dyeing, improving color fastness. Other uses include leather tanning, fire retardants, and decolorizing agents in petroleum. When sourcing, it's important to communicate your primary application to your potential supplier to ensure they can recommend the most suitable grade.

For businesses seeking to secure their supply chain, partnering with a reputable aluminum sulfate manufacturer in China offers several advantages, including access to large-scale production capacities and competitive pricing. When evaluating suppliers, look for companies with robust quality management systems (e.g., ISO certifications), a proven track record, and transparent communication. Understanding the aluminum sulfate price per kg and the total cost of ownership, including shipping and lead times, is crucial for budgeting.
