17% Al₂O₂
A high-purity, white crystalline solid, free from iron impurities. It is the gold standard coagulant for potable water treatment, high-quality paper manufacturing, and textile dyeing where whiteness is paramount.
Aluminium Sulphate (Non-Ferric) is manufactured by reacting Aluminium Trihydrate (ATH) with Sulphuric Acid. Unlike Ferric Alum, which contains iron and has a brownish tint, Non-Ferric Alum is virtually iron-free (max 0.01%) and snow-white in color.
Ruvon International supplies premium grade Non-Ferric Alum that guarantees no discoloration in end products. It acts as a powerful coagulant by neutralizing the electrical charge of suspended particles in water, causing them to clump together (flocculate) and settle down.

Aluminium Sulphate is the industry's most trusted coagulant due to its trivalent aluminium ion (Al³⁺). When added to water, it destabilizes colloidal particles (mud, bacteria, algae) which are negatively charged. This causes rapid floc formation, making it easy to filter out impurities. For paper makers, its low iron content ensures the paper remains bright white and doesn't yellow over time.
Clarification of drinking water and industrial effluent (ETP).
Sizing agent at neutral/acidic pH to improve paper strength.
Acts as a mordant to fix dyes on fabrics.
Used in styptic pencils (stop bleeding) and antiperspirants.
Accelerates concrete setting and acts as waterproofing agent.
Component of foam-based fire extinguishers.
Laminated bags for powder and lumps.
