Abstract:
Boiler water treatment is used to control alkalinity, prevent scaling, correct pH,
and to control conductivity. The boiler water needs to be alkaline and not acidic, so that it
does not ruin the tubes. Boiler water pH refers to a quantitative figure that expresses the
acidity or alkalinity of boiler water. Ideally it should be between 8.5 and 9.5.
If the pH is lower than that, the boiler water will start eating the pipes and attacks
the boiler equipment as well. If it’s higher than that, the boiler water won’t corrode metal,
but it may begin to increase the brittleness of the piping. Also too high pH may result in
attack on copper containing part.
