aluminium sulphate in drinking water Description

  • Sulfate in Drinking-water - World Health Organization

    Aluminium sulfate (alum) is used as a sedimentation agent in the treatment of drinking-water. Copper sulfate has been used for the control of algae in raw and public water supplies (McGuire et al., 1984). 1.4 Environmental fate Sulfates are discharged into water from mines and smelters and from kraft pulp and paper mills, textile mills and

  • Aluminum (Al) and water - Water Treatment and Purification

    Adding aluminum sulphate and lime to water causes aluminum hydroxide formation, which leads to settling of pollutants. Hydroxide is water insoluble, therefore only 0.05 ppm dissolved aluminum remains. This is below the legal limit for drinking water of the World

  • Sulphate | Drinking Water Testing

    Sulphate can be present in water due to man-made and natural processes, but it is often added during the water treatment processing as aluminium sulphate. Sulphate increases the conductivity of water and so enhances corrosion processes which can then lead to a higher concentration of metals in the water.

  • Coagulation and Flocculation in Water and Wastewater

    The World Health Organization in 1993 reduced the arsenic limit for drinking water from 50 mg/l to 10 mg/l. In the United States, since passage of the Safe Drinking Water act in 1976, the maximum allowable arsenic concentration in drinking water was 50 mg/l. In 2002 this limit was lowered to 10 mg/l.

  • Aluminium Sulphate - an overview | ScienceDirect Topics

    The 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.

  • Alum and Ferric Chloride: Pros, Cons - ATS Innova Water

    10/18/2017· The dirtier the water, the more alum you need to feed. Once you feed a certain amount of alum, it essentially quits working. To treat excessively dirty water, simply increasing the alum isn't going to do anything. For example, to treat muddy water like that from the Mississippi, even 250 parts of alum isn't going to cut it.
