WHAT DOES ALUMINIUM SULPHATE MEAN IN ENGLISH?
Aluminium sulfate, alternatively spelled either aluminum or sulphate, is a chemical compound with the formula Al23. It is soluble in water and is mainly used as a flocculating agent in the purification of drinking water and waste water treatment plants, and also in paper manufacturing. Aluminium sulfate is sometimes referred to as a type of alum. Alums are double sulfate salts, with the formula AM 2·12H 2O, where A is a monovalent cation such as potassium or ammonium and M is a trivalent metal ion such as aluminium. The anhydrous form occurs naturally as a rare mineral millosevichite, found e.g. in volcanic environments and on burning coal-mining waste dumps. Aluminium sulfate is rarely, if ever, encountered as the anhydrous salt. It forms a number of different hydrates, of which the hexadecahydrate Al23•16H2O and octadecahydrate Al23•18H2O are the most common. The heptadecahydrate, whose formula can be written as 23•5H2O, occurs naturally as the mineral alunogen.

Under these circumstances it is usually more economic to add sulphuric acid
rather than excess aluminium sulphate to obtain the optimum coagulation pH
value. The use of coagulant to depress the pH would result in more sludge
