ABSTRACT:
An improved method for preparing a basic aluminum hyrdoxy-chlorosulfate is disclosed comprising reacting a basic aluminum chloride with a sulfate source, i.e. H.sub.2 SO.sub.4 or aluminum sulfate, and modifying the reaction product by the addition of minor amounts of calcium containing compound and a water soluble iron salt. The product is useful in water treatment, is effective in cold water as well as low alkalinity water. A magnesium compound can be added to the composition where the calcium source contains no magnesium.
