steam boiler water hardness and ppm

Boiler Water Treatment Guidelines; Columbia Boiler Co

The hardness of water is caused by calcium and magnesium ions which will vary greatly throughout the country depending on the source of the water. In boilers the hardness of the water can cause the formation of scale and sludge or mud. The hardness must be removed in the makeup water to the return system. Total hardness should not exceed 50 PPM

Degrees of Hardness in the PPM of Hard Water | eHow

Moderately hard water has between 75-150 ppm of minerals dissolved in it. Moderately hard water is still safe to drink, but it may leave behind a slightly unpleasant taste. This water will clean with some efficiency, but may leave light yellow spots on laundry or a thin white or oily film on hard surfaces after using it with a cleaning solution.

Total Dissolved Solids - TDS

When the concentration of impurities becomes higher, foam is generated and the volume of the boiling water starts to increase. As a result - more and more low quality wet steam will be generated. The concentration of impurities is often termed TDS - Total Dissolved Solids (ppm) and can be measured using a conductivity or density method.
