Aluminum sulfate, a compound with the chemical formula Al₂(SO₄)₃, is a versatile chemical with a wide array of industrial applications. Its efficacy stems from a unique set of chemical and physical properties that make it indispensable in sectors ranging from water treatment to paper manufacturing and beyond. NINGBO INNO PHARMCHEM CO.,LTD. supplies high-quality aluminum sulfate, ensuring that these critical industrial processes are supported by reliable chemical inputs.

One of the most prominent properties of aluminum sulfate is its acidic nature in aqueous solution. This acidity is due to the hydrolysis of the aluminum ion, which releases protons, thereby lowering the pH. This characteristic is fundamental to its function as a coagulant in water treatment, where the resulting acidic environment can help in the removal of certain contaminants and the effective flocculation process. The white crystalline appearance, available in forms such as flake, granular, or powder, makes it easy to handle and dose in various industrial settings.

The purity of aluminum sulfate is often categorized by its grade, typically referring to the levels of impurities like iron and water-insoluble substances. For instance, 'low ferric' and 'non-ferric' grades are available, catering to applications where even minimal iron contamination is unacceptable, such as in high-purity water systems or certain paper manufacturing processes. The CAS number 10043-01-3 is universally recognized for this compound, ensuring accurate identification in global trade and research.

The industrial significance of aluminum sulfate is vast. In water treatment, its primary function is to clarify water by removing suspended particles that cause turbidity. Its ability to form voluminous flocs that settle quickly is unmatched by many other coagulants. In the paper industry, aluminum sulfate is crucial for sizing, improving ink holdout and reducing feathering. It also plays a role in pH control within the papermaking process, contributing to machine efficiency and product quality. This highlights the importance of aluminum sulfate paper sizing.

Beyond these major applications, aluminum sulfate serves as a mordant in textile dyeing, as mentioned previously, and is used in fire retardants and as a purification agent in petroleum refining. Its broad applicability underscores why businesses frequently search to buy aluminum sulfate online.
