Ferric Aluminium Sulfate Flakes 16% – Cost-Effective Dual Coagulant for Industrial Water Treatment
We supply economical Ferric Aluminium Sulfate (Ferrous Alum) in flake form with a 16% Al₂O₃ content. This dual-action coagulant combines the clarifying power of aluminium with the phosphorus-removing strength of iron. Consequently, industrial wastewater and municipal treatment plants actively use it for phosphate removal, color reduction, and sludge conditioning. Moreover, its flake form ensures easy handling, slow dissolution for controlled reaction, and is a budget-friendly choice for non-potable water applications where iron content is not a concern.
Core Applications for Ferrous Alum in Industrial & Municipal Treatment
This versatile coagulant is engineered for robust performance in demanding wastewater scenarios. Its application targets efficient contaminant removal and cost control.
First, the industrial and municipal wastewater treatment sector relies on ferric aluminium sulfate flakes as a high-value coagulant for phosphorus precipitation and BOD/COD reduction. It is particularly effective for treating wastewater from textiles, food processing, and chemical plants. Therefore, plant managers depend on its dual chemistry to meet discharge limits for nutrients and organic load efficiently.
Second, it serves as an excellent sludge conditioner, improving dewatering characteristics and reducing sludge volume. Furthermore, it is used in pigment manufacturing, as a mordant in dyeing, and for pond and lagoon treatment where its iron content can help control sulfides and odors.
