Aluminium Sulfate (ALUM Powder) is a fine, white to off-white hygroscopic powder used extensively as a coagulant in water and wastewater treatment, paper sizing, textile dyeing, and leather tanning. It works by destabilizing suspended particles in water, making them easier to remove through sedimentation or filtration. Compared to alum lumps, the powdered form dissolves more rapidly and is ideal for applications requiring quick dispersion or where precise dosing is critical.
