Boiler Water Treatment Guidelines; Columbia Boiler Co

The best test for the determination of solids content of the boiler water is through a conductance test. The conductance value of boiler water varies by the various ionized salts present. The conductance can be used to measure the total dissolved solids in the boiler water and to serve as an accurate means of the control of solids through the

Water Handbook - Boiler System Failures | SUEZ

The boiler water often contains elements that become corrosive when concentrated far beyond normal values as a result of design problems. Many industrial boilers, for example, are treated in such a manner that low concentrations of caustic soda are present in the boiler water. The caustic can become corrosive to steel when the boiler water is

Water Hardness - an overview | ScienceDirect Topics

Water hardness is handled a little differently from salinity in that in some countries the degree is the unit of measure. One German degree of hardness equals 10mg/liter (ppm) of calcium and magnesium oxide or 17.8ppm of CaCO 3 in the USA. This is not at all equivalent to salinity in that a relatively low salinity water rich in calcium and magnesium could have a relatively high degree of hardness.

How to Measure Water Hardness - water hardness test kit guide

Water hardness or other water test kits are used in a very wide variety of applications beyond simply checking a drinking water supply. Some other uses include balancing the water hardness of pools and spas, testing the condensate in a steam boiler system or in water operated cooling towers, and checking the proper operation of water softeners.
