More DetailsAnhydrous aluminum sulfate is a white crystalline solid. Aluminum sulfate is also obtained as an 18-hydrate Al2 (SO4)3.18H2O. Both forms are soluble in water, noncombustible, and nontoxic. The primary hazard is the threat to the environment. Immediate steps …
More DetailsAlum is applied to lake water as aluminum sulfate, or Al 2 (SO 4) 3 · 14 H 2 O. As aluminum sulfate is added to water, it forms aluminum ions, which are hydrated (combined with water): Al +3 + 6 H 2 O ⇄ Al (H 2 O) 63+. In a series of chemical hydrolysis steps, hydrogen ions are liberated, which may lower the water pH, and ultimately forms ...

More DetailsWater. Like oxygen, water is a colorless and odorless substance made up of billions of molecules formed by the combination of oxygen and hydrogen. On Earth, water is found in three different forms. As a gas, it is a vapor in the atmosphere. In its solid form, it can be found on frozen rivers and ponds. The final form, liquid, is 71% of our planet.

More DetailsAn alum (/ ˈ æ l ə m /) is a type of chemical compound, usually a hydrated double sulfate salt of aluminium with the general formula XAl(SO 4) 2 ·12H 2 O, where X is a monovalent cation such as potassium or ammonium. By itself, "alum" often refers to potassium alum, with the formula KAl(SO 4) 2 ·12H 2 O.Other alums are named after the monovalent ion, such as sodium alum and ammonium alum.
More Details· Hydrolysis of alum is mentioned in the AWWA Water Treatment book although there is no source listed for the information. However, hydrolysis of alum is probably not probable in a normal water treatment application. Aluminum sulfate poorly ionizes and you would need to raise the pH above 3.5 for hydrolysis to occur.
More DetailsThe 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, thereby minimizing the need for coagulation pH adjustment and reducing the alkali dose required for subsequent final pH correction.
