There is disclosed a continuous process for the manufacture of aluminum sulfate by the reaction of sulfuric acid with an alumina-containing solid in an aqueous suspension. The reaction stream is passed into a continuous flow reaction zone that is maintained at a temperature controlled from 225° to 260° F. and under superatmospheric pressure, preferably, autogenic pressure.


Although sulphur is the cheapest acidifier and least likely to harm plants, other materials are sometimes used: Aluminium sulphate. This is used in hydrangea ‘blueing agents’ to obtain blue flowers where the soil conditions are not sufficiently acid to give blue flowers naturally. Aluminium sulphate can also be used as a soil acidifier.

However, some plants, including hydrangeas, azaleas, grapes, strawberries and blueberries, require more acidic soil. This is where alum comes in – aluminum sulfate can be used to lower soil pH, thus making the soil suitable for acid-loving plants. If your acidic plants aren’t thriving, take a soil test before you attempt to adjust the pH level.
