Description

Sulphuric Acid, Aluminium Salt CAS NO 10124-29-5 is an inorganic salt widely recognized for its role as a coagulating and flocculating agent. This compound is critical in industrial water treatment processes for purifying drinking water and treating wastewater. It is essential for manufacturers and processors in the paper, textile, and chemical synthesis industries who require reliable and effective purification agents.

Application

• Water Treatment: Primary use as a coagulant for the removal of suspended solids, organic matter, and phosphates in municipal drinking water and industrial wastewater plants.
• Paper Manufacturing: Acts as a retention aid and drainage promoter in the papermaking process, improving sheet formation and water removal.
• Textile Industry: Used in dyeing and printing processes as a mordant to fix dyes onto fabrics and in wastewater treatment from dye houses.
• Cosmetics & Personal Care: Employed as an active ingredient in antiperspirants due to its astringent properties.
• Catalyst & Chemical Synthesis: Serves as a catalyst or a reagent in various organic synthesis reactions and the production of other aluminum compounds.
• Construction: Used as an additive in some cement formulations and grouts to accelerate setting time and improve early strength.
