Ferric Aluminium Sulphate, also known as Ferric Alum, is an inorganic compound that combines aluminium sulphate and ferric sulphate. It appears as a light brown to reddish solid or powder and is highly soluble in water. This compound acts as a dual coagulant, offering the benefits of both aluminium and iron salts.
Ferric Aluminium Sulphate is primarily used in water and wastewater treatment to remove suspended particles, turbidity, and phosphorus. It also finds applications in paper sizing, textile processing, and dye manufacturing due to its effective coagulating and settling properties.
Ferric Aluminium Sulphate is commonly used in:
Drinking water purification
Sewage and effluent treatment plants
Paper and pulp industry (as a sizing agent)
Textile and dyeing industry (for dye fixation and treatment)
Leather industry (for tanning and wastewater treatment)
Efficient dual coagulant – combines benefits of aluminium and ferric salts
Enhances flocculation and sedimentation
Effective in a broad pH range
Reduces color, turbidity, and phosphorus in water
Suitable for industrial and municipal water treatment
