#Aluminum_Sulfate has many different uses in day-to-day life, as well as being used in several essential industries.
Interesting uses of aluminum-sulfate around the house are in gardening. Because #aluminum_sulfate is extremely acidic, itâ??s sometimes added to very #alkaline soils to balance the pH for plants. When the #aluminum_sulfate comes into contact with water, it forms #aluminum_hydroxide and a much diluted sulfuric acid solution, which alters the soil acidity.
All levels of crude #aluminum_sulfate can be used for water purification and water treatment ; #aluminum_sulfate used for purification cannot be produced by waste acid toxic substances.

Aluminium Sulfate (Al(SO)) - Versatile Industrial Coagulant & Chemical Intermediate
Product Overview
Aluminium sulfate is a water-soluble inorganic salt with the formula Al(SO), 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 Al(SO)·16HO and octadecahydrate Al(SO)·18HO), 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
·Papermakers 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 CO-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).
