Product Description
Aluminum Sulfate Al₂(SO₄)₃
Water Treatment Coagulant, Paper Sizing Agent, Soil pH Adjuster
Aluminum sulfate, with the chemical formula Al₂(SO₄)₃, commonly exists in hydrated forms (e.g., octadecahydrate). This product is a white or slightly grayish crystalline, flake, or lump solid. As one of the oldest and most widely used inorganic coagulants, aluminum sulfate continues to play a fundamental and crucial role in both traditional and modern industries—including water treatment, papermaking, firefighting, chemicals, and soil amendment—relying on its reliable capabilities in charge neutralization, adsorption bridging, and sweep coagulation.
Core Applications
Water Treatment Coagulant - The most commonly used coagulant in waterworks and wastewater treatment plants. Upon addition to water, it rapidly hydrolyzes, generating positively charged aluminum hydroxide colloids that efficiently adsorb and agglomerate negatively charged suspended particles, colloidal impurities, organic matter, and microorganisms.
Paper Industry Fixative - Traditionally employed as the fixative for acidic sizing in papermaking processes. Promotes precipitation and fixation of rosin size onto fibers, enhancing paper's water resistance. Still used in specialty papers and acidic system papermaking.
Soil Management & Firefighting -
- Soil pH Adjuster - Lowers soil pH for acid-loving plants like azaleas, camellias, and blueberries
- Firefighting Foam Raw Material - Important chemical for producing protein-based and synthetic firefighting foams
- Additional Applications - Fat and oil clarification, catalyst support manufacturing, pigment precipitation, and tanning
Modern Industrial Applications - Maintains irreplaceable position due to extremely low cost, simple production process, and no risk of residual toxicity. Essential for budget-sensitive water treatment projects and as raw material for producing other aluminum salts.
