Aluminum sulfate, is one of the most commonly used coagulants for treating potable water and wastewater. As a municipality, industrial plant, or private water utility, you require the chemicals and support to ensure your finished water meets the health and …
Using aluminum sulfate means that the paper was made under acidic conditions. Use of synthetic sizing agents means that acid-free paper can be produced. Acid-free paper does not break down as fast as paper sized with acid. Though you may not have known it, aluminum sulfate is used to make many products you use daily.
Aluminum Sulfate is an odorless, lustrous white to grayish-white crystalline, granular or powdered solid. This material can cause severe irritation and inflammation, or burns to the eyes and skin. Contact with high concentration or prolonged contact may cause permanent damage.
To most people, alum means hydrated ,aluminum sulfate,, which is the salt of sulfuric acid (a strong acid) and ,aluminum, hydroxide (a weak base). Alum is also known as papermakers' or filter alum. Almost all the alum produced in the United States today is manufactured from bauxite, bauxitic clays and other clays, which are found primarily in Alabama, Arkansas, Georgia, and Missouri.
Aluminum sulfate has an action similar to that of alum but is more stringent (2). Aluminum sulfate is an aluminum salt composed of aluminum, sulfur, and oxygen, three plentiful elements. Its molecular formula is Al2(SO4)3 or Al2S3O12 or Al2O12S3. Properties
Aluminium sulphate is the most widely used aluminium coagulant (Section 8.20). It is available in a number of solid grades such as block, kibbled or ground and is also available as a solution typically containing 8–8.3% w/w Al 2 O 3. In waterworks practice aluminium sulphate is frequently but incorrectly referred to as ‘alum’.
Aluminum sulfate is white or off-white crystals or powder. It is not volatile or flammable. It has a low pH when combined with water making it capable of burning skin or corroding metal, is water soluble, and able to hold water molecules.
Aluminium sulfate is a chemical compound with the formula Al 2 (SO 4) 3. It is soluble in water and is mainly used as a coagulating agent (promoting particle collision by neutralizing charge) in the purification of drinking water and waste water treatment plants, and also in paper manufacturing.
