In these reactions, dissolved solids are not reduced because a solution reaction product (sodium sulfate or sodium chloride) is formed. Warm Lime Softening. The warm lime softening process operates in the temperature range of 120-140°F (49-60°C). The solubilities of calcium, magnesium, and silica are reduced by increased temperature.
Aluminium sulfate is mainly used in water treatment, dyeing, leather tanning and in the production of other aluminium compounds. Aluminum Sulfate (Alum) is a white crystalline product which is almost insoluble in anhydrous alcohol, but readily soluble in water.

Although concern over the safety of treating water with aluminum has often been voiced, there is no evidence that aluminum in water, whether it comes from the aluminum sulfate used in treatment or from other sources, is a health issue. Actually, most aluminum that we take in does come from other sources.
Aluminum Alum or hydrated aluminum sulphate is widely used precipitating phosphates and aluminum phosphates (AlPO4). The basic reaction is: Al3++ H nPO4 3-n ↔ AlPO 4+ nH + The dosage rate required is a function of the phosphorous removal required. The efficiency of coagulation falls as the concentration of phosphorous decreases.

Aluminium sulphate is the most widely used aluminium coagulant (Section 8.20). It is available in a number of solid grades such as block, kibbled or ground and is also available as a solution typically containing 8–8.3% w/w Al 2 O 3. In waterworks practice aluminium sulphate is frequently but incorrectly referred to as 'alum'.
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.
