Where is Aluminum ammonium sulfate dodecahydrate used?

• Water treatment: coagulant and flocculant that aggregates suspended particles; pH-buffering agent in process streams
• Municipal and industrial water treatment: destabilizes colloidal particles and clarifies raw water ahead of filtration
• Textile and leather processing: mordant that fixes dyes onto fiber substrates
• Pulp and paper production: sizing precipitant that helps rosin size bind to cellulose fibers
• Agriculture: soil amendment and fertilizer formulations where aluminum and ammonium ions contribute to pH correction and nutrient delivery

Commercial specifications
