Aluminium Sulfate (Al₂(SO₄)₃) - Versatile Industrial Coagulant & Chemical Intermediate Product Overview Aluminium sulfate is a water-soluble inorganic salt with the formula Al₂(SO₄)₃, widely recognized for its role as a coagulating agent in water treatment and as a key additive in paper manufacturing. Available in anhydrous form (rare mineral millosevichite) and hydrated forms (notably hexadecahydrate Al₂(SO₄)₃·16H₂O and octadecahydrate Al₂(SO₄)₃·18H₂O), this compound delivers exceptional performance across industrial, environmental, and technical applications. Key Applications 1. Water Treatment & Purification Coagulant for Drinking Water & Wastewater: Neutralizes particle charges to promote flocculation, removing impurities in municipal and industrial water systems. Pool & Cooling Tower Treatment: Efficiently clarifies water by precipitating suspended solids. Mining Wastewater: Reduces turbidity and heavy metal ions through coagulation. 2. Paper Manufacturing Papermaker’s Alum: Acts as a sizing agent to improve ink retention and paper strength, and as a flocculant in pulp processing. 3. Construction & Fire Safety Concrete Accelerator & Waterproofing Agent: Speeds up setting time and enhances water resistance. Fire Extinguishing Foam: Reacts with sodium bicarbonate to generate CO₂-rich foam, smothering hydrocarbon fires (commonly used in Japan/India). 4. Agriculture & Horticulture Soil pH Regulator: Lowers soil alkalinity, ideal for acid-loving plants (e.g., hydrangeas, which change flower color with pH adjustment). Molluscicide: Effective against Spanish slugs in agricultural settings. 5. Industrial & Chemical Synthesis Textile Dyeing Mordant: Fixes dyes to fibers by forming insoluble pigment- alum complexes. Phase Transfer Catalyst: Facilitates organic reactions (e.g., Williamson ether synthesis). Antiperspirant & Medicinal Ingredients: Historical use in antiperspirants and sting relief products (e.g., Stingose).
