Aug 23, 2017 · The calculation of hardness in water by EDTA titration can be found by adding a small amount of a dye such as Erichrome Black Tis added to an aqueous solution containing Ca++ and Mg++ ions at a pH of 10 ± 0.1, Ca++ and Mg++ form chelated complexes of wine red colour with EBT. But EDTA has a stronger affinity towards Ca++ and Mg++.

Apr 27, 2015 · The boiler sludge produced by this reaction is effectively removed by routine surface and bottom blowdown. Magnesium hardness reacts with silica and hydroxide alkalinity to yield an insoluble sludge. In general, boiler blowdown is controlled such that the suspended solids produced by these precipitation reactions do not exceed 500 ppm.
