Characterization of Boiler Water from Various Industries

feed water is kept very low usually < 0.2 ppm. All the feed water samples have very high value of hardness i.e., 110.0-32.5 ppm in case of total hardness, 24.0-1.6 ppm for calcium hardness and 3.0-2.01 ppm as magnesium hardness. Hence, the feed water in theses cases is not suitable for boiler feed and also is untreated or taken from natural source.
