Engineering ToolBox - Resources, Tools and Basic Information for Engineering and Design of Technical Applications! Typiclal limits for impurities in drinking water.
Typical limits for impurities in water supply systems:
Drinking Water Supply Systems - Impurity Limits Impurity Limit ( ppm) Color 20 Copper 3.0 Fluoride 1.0 Hardness, Ca and Mg salts 100 Lead 0.1 Magnesium 125 Iron plus manganese 0.3 Solids 500 Turbidity 10
Turbidity is is an optical characteristic and a the measure of the relative clarity of a liquid. It is a measurement of the amount of light that is scattered by material in the water when a light is shined through it. High intensity of scattered light equals to high turbidity.
