Ferric Aluminium Sulfate Granular 16% – Robust Dual-Action Coagulant for Wastewater & Industrial Use
We supply industrial-grade Ferric Aluminium Sulfate (Ferrous Alum) in granular form with a 16% Al₂O₃ content. This dual-coagulant combines aluminium’s flocculation with iron’s phosphate removal strength. Consequently, wastewater treatment plants actively use it for efficient phosphorus precipitation, BOD/COD reduction, and sludge conditioning. Moreover, its granular form ensures controlled dissolution, easy handling, and is a cost-effective solution for industrial effluent and municipal sewage treatment where iron content is acceptable.
Core Applications for Granular Ferrous Alum in Treatment Processes
This powerful coagulant is engineered for demanding, high-load wastewater scenarios. Its application delivers robust contaminant removal and process efficiency.
First, the industrial and municipal wastewater sector relies on ferric aluminium sulfate granular as a primary coagulant for nutrient removal and organic load reduction. It effectively treats effluent from food processing, textiles, tanneries, and chemical manufacturing. Therefore, plant operators depend on its dual chemistry to consistently meet stringent discharge regulations for phosphorus and organic matter.
Second, it serves as a highly effective sludge conditioner, improving dewaterability and reducing final sludge volume. Furthermore, it is utilized in pigment production, as a mordant in dyeing, and for algae and odor control in ponds and lagoons.
