Aluminium Sulphate (Ferric)
Ferric Aluminium Sulphate, commonly known as Ferric Alum, is a powerful coagulant and precipitant widely used in water treatment, paper manufacturing, and dyeing applications. It is typically supplied in powder, granule, or slab form and has a brownish or reddish tint due to iron content. In municipal and industrial water systems, it aids in removing suspended solids, improving clarity, and controlling odor. Its cost-effectiveness and efficiency make it a preferred coagulant in the public and private sectors alike.
