Production Methods of Aluminum Sulphate. There are several methods for producing aluminum Sulphate, but one of the most common approaches involves the reaction of aluminum hydroxide with sulfuric acid. This process is carried out in a controlled environment to ensure the proper stoichiometric ratio between the reactants.
Traditionally, aluminium sulfate powder is produced by freeze-drying, spray-drying, and conventional drying of alumina sol in an oven at different temperatures and pressures [28], [29]. However, the production method solely utilizing drying has serious disadvantages. First, drying times are typically long due to low solid content in the sol.
