Alums are useful for a range of industrial processes. They are soluble inwater; have anastringent, acid, and sweetish taste; reactacidtolitmus; andcrystallizein regularoctahedra. When heated they liquefy; and if the heating is continued, thewater of crystallizationis driven off, the salt froths and swells, and at last an amorphous powder remains.Industrial uses
Potassium alumis the common alum of commerce, althoughsoda alum,ferric alum, andammonium alumare manufactured.
Alum has been used at least since Roman times for purification of drinking waterand industrial process water. Between 30 and 40ppmof alumfor household wastewater, often more for industrial wastewater, is added to the water so that the negatively charged colloidal particles clump together into "flocs", which then float to the top of the liquid,settleto the bottom of the liquid, or can be more easilyfilteredfrom the liquid, prior to further filtration and disinfection of the water.
