To most people, alum means hydrated aluminum sulfate, which is the salt of sulfuric ,acid, (a strong ,acid,) and aluminum hydroxide (a weak base). Alum is also known as papermakers' or filter alum. Almost all the alum produced in the United States today is manufactured from bauxite, bauxitic clays and other clays, which are found primarily in Alabama, Arkansas, Georgia, and Missouri.

Coagulation-flocculation is used to remove helminth ova from ,wastewater, intended for agricultural reuse. Nevertheless, it has the drawback of producing a large amount of sludge which together with the chemicals used to treat the ,wastewater, increases the operating cost. This can be overcome by recovering and recycling the aluminium contained in the sludge. This paper presents how an ,acid, ...

This is a method applied several decades ago in water sludge that has not been used in secondary wastewater sludge to recover aluminium and to inactivate microorganisms. By adding sulphuric acid to a 6%TS sludge, more than 70% of the aluminium added during the coagulation flocculation process was recovered when a pH of 2 was maintained during 30 minutes and at 300 rpm of mixing conditions.

Acid alum formulations are aluminum sulfate with 1 to 15-percent free sulfuric acid. Their effectiveness with TOC removal applications is due to the enhanced depression of pH. TOC or NOM reductions depend on the type and dosage of coagulant, the pH, temperature, raw water quality and NOM characteristics.

When cryolite is used as the ore for producing alum, it is mixed with calcium carbonate and heated. By this means, sodium aluminate is formed; it is then extracted with water and precipitated either by sodium bicarbonate or by passing a current of carbon dioxide through the solution. The precipitate is then dissolved in sulfuric acid.
