Description

Aluminiumsulfate CAS NO 22337-62-8 is an inorganic salt widely recognized for its efficacy as a primary coagulating and flocculating agent. This compound is critical for purifying water by removing suspended particles, color, and microorganisms, ensuring compliance with environmental and safety standards. It is an essential raw material for industries including water treatment, paper manufacturing, and textile processing, where reliable quality and consistent performance are paramount.

Application

• Water and Wastewater Treatment: Primary coagulant for the removal of turbidity, phosphates, and organic matter in municipal and industrial water purification plants.
• Paper Manufacturing: Used as a sizing agent and retention aid to improve paper sheet formation, water resistance, and printability.
• Textile Industry: Serves as a mordant in dyeing processes to fix colors onto fabrics, improving color fastness and uniformity.
• Cosmetics and Personal Care: Acts as an astringent and antiperspirant agent in the formulation of deodorants and skin care products.
• Construction: Employed as an accelerator in concrete setting and for soil stabilization in certain geotechnical applications.
• Firefighting Foams: A component in some Class A firefighting foams for its ability to penetrate and wet burning materials.
