Ferric Alum powder

Ferric alum powder FeNH₄(SO₄)₂·12H₂O (or similar iron-containing aluminum sulfate) is a highly soluble, pale violet or white crystalline substance primarily used as a powerful inorganic coagulant and flocculant in industrial wastewater treatment and water purification. It effectively removes suspended impurities, colloids, and phosphorus from water. Beyond water treatment, this versatile industrial chemical is heavily utilized as a sizing agent in the pulp and paper industry, a mordant in textile dyeing, and an etching agent.
