Uses and synthesis of Aluminum sulfate powder

Aluminum sulfate powder is an important inorganic compound. Aluminum sulfate is a white crystalline solid, odorless. It dissolves easily in water and forms sulfate ions and aluminum ions. Aluminum sulfate is acidic and reacts with alkali to produce salt and water. It has strong hygroscopicity. Aluminum sulfate is widely used in water treatment, such as sewage treatment, drinking water purification, and industrial wastewater treatment.

Comparison of Different Forms.

Applications/Functions of Aluminum sulfate powder

2. Aluminum sulfate is used in the production of artificial gemstones and high-grade ammonium alum.

Physicochemical Property of Aluminum sulfate powder

Aluminum sulfate is a white, grayish green or light yellow flake or block solid, and liquid aluminum sulfate is a light green or light yellow liquid. Soluble in water, acid and base, insoluble in alcohol. The aqueous solution is acidic and produces aluminum hydroxide after hydrolysis.

Production methodprocess of Aluminum sulfate powder

Aluminum sulfate powder is made by reacting aluminum hydroxide (or pure kaolin or bauxite) with sulfuric acid, filtering out the insoluble matter and recrystallizing it..

FAQ.

Q1: Which is better, aluminum sulfate or polyaluminum chloride (PAC)?

✅ Aluminum sulfate is cost-effective and suitable for general wastewater treatment

✅ PAC has stronger flocculation effects but is more expensive

Q2: Does aluminum sulfate leave residual aluminum ions? How can this be avoided?

Control the dosage (5–50 mg/L)

Subsequent filtration or pH adjustment can reduce residuals

Q3: Where can I purchase high-purity aluminum sulfate?

Industrial grade: Chinese suppliers (e.g., Jiangxi Copper)

Food grade: North American Chemtrade or European Kemira
