Abstract:
A process for producing a polyaluminum chlorosulfate (PACS) includes adding an aluminum hydroxychloride (AHC) solution having about 38-43% basicity with (1) aqueous aluminum sulfate to form a solution and mixing a solid AHC with the solution to form an aqueous milky suspension or (2) a solid AHC and solid aluminum sulfate and adding water to the solid mixture to form an aqueous milky suspension, and maintaining the milky suspension for a period sufficient to allow the milky suspension to form a clear to slightly turbid solution including the PACS, the PACS having a basicity of 55 to 75%, the average molecular weight of the PACS is greater than or equal to 95 and less than or equal to 111, and salts present in the PACS comprise 0-1.0% sodium chloride by weight and 0-1.0% sodium sulfate by weight.

Claim (Index 9):
The process of  claim 1 , wherein the clear to slightly turbid solution formed in step e) is by mixing the milky suspension while gradually increasing its temperature until the clear to slightly turbid solution is obtained.
