Alum, also known as potassium aluminum sulfate, can be used to purify water. … Alum in its powdered form can be added to water to bind with phosphorous particles to aid the water purification process.
Alum is used to coagulate suspended particles, algae, protozoa, viruses, bacteria, and some metal ions (such as iron and manganese) into larger particles. The resulting “sludge” is then removed. Ozone may be bubbled through the water to kill remaining bacteria, viruses, and protozoa.
Also, Why alum is used in purification of water?
In a typical water treatment process: Alum is used to coagulate suspended particles, algae, protozoa, viruses, bacteria, and some metal ions (such as iron and manganese) into larger particles. The resulting “sludge” is then removed.
Hereof, Is alum water safe for drinking?

Likewise, What is the role of alum in the purification of water?
To accomplish this, the water is treated with aluminum sulfate, commonly called alum, which serves as a flocculant. Raw water often holds tiny suspended particles that are very difficult for a filter to catch. … The alum promotes coagulation of fine particles which helps resolve problems of color as well as turbidity.
