Apr 05, 2020 · Because of this latter phenomenon, where "soft" water is used for boiler structure, any Magnesium present must be removed along with the Calcium. Magnesium Sulphate (MgSO 4 ) Magnesium Sulphate is an extremely soluble salt, having a solubility of 20 % in cold water and 42 % in boiling water.

May 04, 2016 · The conductivity test can be used as a simple and accurate method of blowdown control; but, it should be used for this purpose after a firm correlation has been established between conductivity, total dissolved solids, and chlorides. Hardness Test. Water hardness is composed primarily of dissolved calcium and magnesium compounds.
1.1 These test methods cover the determination of calcium and magnesium in water by complexometric titration and atomic absorption spectrometric procedures. Two test methods are included, as follows: Two test methods are included, as follows
Why is Boiler Water Testing Necessary? The quality and quantity of water are critical to boiler operation. The two main problems for boilers under 300 psig are scale and corrosion. Scaling is the deposition of Calcium and Magnesium salts on the waterside surfaces in the boiler. Corrosion is the result of Oxygen reacting with the metal surfaces.
