how does aluminum sulfate used in water treatment

  • (

    Aluminum sulfate, aka "filter alum" , is commonly used as a coagulant in water treatment systems and less frequently in waste treatment systems In water treatment it is used primarily for the removal of tiny particles (called colloids, measured as total suspended solids) in the raw water which are too small to settle by gravity inThe facts about human health and aluminum in drinking water Aluminum is the third most common element in the earth's crust and is present in soil, water and air Aluminum's physical and chemical properties make it ideal for a variety of uses in food, drugs, consumer products, and water treatment.
