Abstract
A method of processing a non-virgin sulfuric acid solution for the preparation of aluminum sulfate comprises the steps of combining a sulfuric acid solution having less than 90% sulfuric acid with water to form a mixed solution of no less than about 10% sulfuric acid. An alumina-containing compound such as aluminum hydroxide or aluminum bauxite is then added, the combination forming a pH of 2.0 or less. Once a specific gravity of less than about 1.36 is reached, the aluminum sulfate cools and settles overnight before filtering and/or storing.
