Focus on information value

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, …

the aluminum smelting process : journal of occupational

Aluminum salts such as potassium aluminum sulfate (alum) are often used for flocculation during the water purification process (mainly surface water). This treatment lowers concentrations of organic materials in the water, reduces the presence of microorganisms (viruses, bacteria, and parasites) that can cause infectious diseases, and improves water color and turbidity
