Why is aluminum sulfate important?
Aluminum sulfate is also important for lake treatment and restoration. Untreated wastewater and potable water have negatively charged suspended colloids, and water treatment systems use positively charged metallic salts, such as aluminum sulfate, to destabilize the colloidal particles. As a coagulant, aluminum sulfate enhances the removal ...
Does aluminum sulfate remove bacteria?
While aluminum sulfate helps remove large amounts of organic compounds in potable water and wastewater, it isn't enough to remove pathogens, such as bacteria and viruses. However, aluminum sulfate is a primary step in water purification, as it prepares the water for further filtration.

Is it safe to drink water with alum?
the csIro has conducted extensive research in this matter and in late 1998 found convincing evidence that the use of alum to treat drinking water is safe. the csIro found that the aluminium we obtain from treated drinking water is an insignificant amount: only 1 to 2% of our daily intake of aluminium comes from water and only the barest trace of this is absorbed. Most of the aluminium absorbed is excreted through urine.
Is aluminium a pure metal?
aluminium is the third most abundant element and comprises about 8% of the earth’s crust. It is never found in its natural form as a pure metal but is always locked in, or mixed with, other elements as very stable chemical compounds such as alumino-silicates. It occurs in most rocks, vegetation and soils (such as clay etc) in this combined form. aluminium is widely used in many industrial and domestic products including antacids, antiperspirants and food additives, and in vaccines. It is
