Aluminium Sulfate

Aluminium Sulfate (Chemical Formula:  CAS No.: 10043-01-3) is a water-soluble inorganic salt renowned for its versatility as a coagulant, chemical intermediate, and additive across multiple industries. It exists in anhydrous form (rare mineral millosevichite) and hydrated forms (e.g., hexadecahydrate, octadecahydrate, delivering exceptional performance in water treatment, paper manufacturing, construction, agriculture, and beyond.

Key Applications:
Water Treatment & Purification
Acts as a coagulant in drinking water/wastewater systems, neutralizing particle charges to enable flocculation and impurity removal.
Clarifies water in pools and cooling towers by precipitating suspended solids.
Reduces turbidity and heavy metal ions in mining wastewater via coagulation.
Paper Manufacturing
Serves as papermakers alum a sizing agent to enhance ink retention and paper strength, and as a flocculant during pulp processing.
Construction & Fire Safety
Functions as a concrete accelerator (speeds up setting time) and waterproofing agent (boosts water resistance).
Forms CO-rich fire-extinguishing foam when reacting with sodium bicarbonate, effective for smothering hydrocarbon fires (widely used in Japan, India, etc.).
Agriculture & Horticulture
Regulates soil pH (lowers alkalinity), ideal for acid-loving plants (e.g., hydrangeas, where pH adjustment alters flower color).
Acts as a molluscicide to control Spanish slugs in agricultural settings.
Industrial & Chemical Synthesis
Serves as a mordant in textile dyeing, fixing dyes to fibers via insoluble pigment-alum complexes.
Facilitates organic reactions (e.g., Williamson ether synthesis) as a phase transfer catalyst.
Historically used in antiperspirants and sting relief products (e.g., Stingose).
