standard for the supply of aluminium sulphate for water new

The Risk Assessment Information System

The Drinking Water Standards of the U.S. Public Health Service recommend that sulfate in water should not exceed 250 mg/L, except when no more suitable supplies are or can be made available. The World Health Organization, in the European Standards for Drinking Water, also set a sulfate limit of 250 mg/L (NAS, 1977).

Ammonium Sulfate Calculator from EnCor Biotechnology Inc.

How the program works: Ammonium Sulfate is very soluble in water so saturated ammonium sulfate is a 4.1M solution at 25 o C, 4.06M at 20 o C, 3.97M at 10 o C, 3.93M at 4 o C and 3.9M at 0 o C. The molecular formula of ammonium sulfate (NH 4 ) 2 S0 4 and the molecular weight is 132.14, so that saturation occurs at 541.8 g/L at 25 o C, 536.49 g/L ...
