Characteristics of Polyaluminum Chloride (PAC) Coagulant Prepared by Baking Process
Polyaluminium chloride (PAC) is an important flocculation in water treatment. O’Melia and Dempsey (1982), in a review of work done using a wide variety of PAC coagulants, proposed that some PAC for-mulations may contain aluminum precipitates.
aluminium sulphate has been in operation for over a hundred years all over the world. The use of alum as a coagulant for water treatment often leads to higher concentrations of aluminium in the treated water than in the raw water itself.

Complexometric determination of aluminum
Direct determination of aluminum with EDTA is impossible - complexation reaction is too slow, making titration impractical. However, there are not many simple methods of aluminum determination, and complex stability constant for Al 3+ is so
Aluminium chloride (AlCl3), also known as aluminium trichloride, describe compounds with the formula AlCl3(H2O)n (n = 0 or 6). They consist of aluminium and chlorine atoms in a 1:3 ratio, and one form also contains six waters of hydration. Both
