Aluminium Sulphate an overview ScienceDirect Topics

Aluminium sulphate has zero basicity whereas that of the polymerized aluminium salts varies from about 50% for Al 2 (OH) 3 Cl 3 (i.e. 10% w/w Al 2 O 3) to about 85% for ACH (24% w/w Al 2 O 3). The H + ions produced by aluminium sulphate, PACl (10% w/w Al 2 O 3) and ACH are 6, 3 and 1, respectively. High basicity coagulants therefore depress the pH of the treated water less than aluminium sulphate,

Aluminium production process
