Application

1. Water Treatment

As a core coagulant, potassium aluminium sulfate undergoes hydrolysis to form aluminum hydroxide colloid (Al(OH)₃), which efficiently removes contaminants via:

Charge neutralization (destabilizing suspended particles)

Adsorption & bridging (flocculating colloidal and dissolved pollutants, including phosphates & SS)

2. Cosmetics & Personal Care

Utilized for its multifunctional properties:

Astringent action (Al³⁺ tightens skin by contracting proteins)

Sebum control (oil-reducing effect)

Antimicrobial activity (inhibits bacterial growth in deodorants)

3. Food Industry

Approved as a food additive (E522) for:

Leavening agent (in baked goods, providing texture via gas release)

Preservative (extends shelf life by microbial inhibition)

Pickling firming agent (maintains crispness in fermented vegetables
