Aluminum Sulphate (Al₂(SO₄)₃) is an inorganic salt commonly used in water and wastewater treatment as a coagulant. It helps remove suspended particles by causing them to clump together for easier sedimentation and filtration. It is also used in paper manufacturing, textile processing, and as a mordant in dyeing.
