Description

Sulfuric Acid, Aluminum Salt (3:2), Tetradecahydrate is a hydrated aluminum sulfate compound, commonly known as aluminum sulfate octadecahydrate. This versatile inorganic salt is valued for its efficacy as a flocculating and precipitating agent in water purification and industrial processes. It serves as a critical raw material for manufacturers in the water treatment, paper production, textile, and chemical synthesis sectors, where reliable quality and consistent performance are paramount.

Application

• Water and Wastewater Treatment: Primary application as a highly effective coagulant for removing suspended solids, colloidal particles, and phosphates.
• Paper Manufacturing: Used in sizing and pH control to improve paper quality, ink retention, and water resistance.
• Textile Industry: Employed as a mordant in dyeing processes to fix colors onto fabrics and in fireproofing treatments.
• Chemical Synthesis: Acts as a catalyst or raw material in the production of other aluminum compounds and various chemicals.
• Construction: Utilized as an accelerator in concrete setting and for soil stabilization.
• Cosmetics & Personal Care: Found in astringents and as a hardness agent in some formulations.
