Aluminium Sulphate (Non Ferric) Non-Ferric Alum is a high-purity, low-iron form of Aluminium Sulphate, typically appearing as a white or near-white crystalline solid. It is favored for applications where clarity, whiteness, or color precision is critical—such as drinking water purification, white paper production, cosmetics, and high-end textiles. Unlike Ferric Alum, it does not impart a yellow or brown tint, making it ideal for color-sensitive processes. Supplied in powder, granule, or slab form, it offers excellent solubility and fast reactivity.

Preferred for potable water due to its low iron content, which ensures color-free and clear treated water. Improves paper sizing and ink absorbency. Prevents pitch deposits and enhances filler retention. Used as a mordant to enhance dye bonding to natural fibers. Ideal where bright and pure dye shades are required without iron interference. Helps in deliming hides and softening leather during tanning without darkening the leather. Used in deodorants, aftershaves, and topical antiseptics. Also found in veterinary products and tablets as astringents and clarifiers. Applied in chemical analysis and sample preparation, especially where iron contamination must be avoided.

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.

Helps in clarification and sludge thickening in drinking water and ETP/STP plants. Enhances sizing and improves retention of fillers and fibers, giving paper a smoother finish. Controls resinous deposits and improves dye adhesion. Used as a mordant in dyeing processes for color fastness. Also helps neutralize alkalis in dye baths. Aids in pickling hides, preparing them for chrome tanning. Helps in removing greases and fats from leather. Used as an additive in quick-setting and waterproofing cements. Also helps reduce efflorescence in concrete products. Acts as a flocculant to separate fine solids in mineral ore processing.
