: 1.can someone explain the chemical processes when chemicals are used to test the BW condition?
: e.g.,5ml of water+phenolphthalain.... so on
: 2.info on deionized water employment in boilers(what is it?what is the harm if we use it?)
Phenolphthalein is simply an indicator of pH. It changes color at different pH values.
In order to learn about the chemical processes, purchase Betz Handbook of Water Treatment. It explains it all.
No harm in using di water, it is a good way to go. You will have to add some alkalinity builder to get proper ph
and alkalinity. DI water is water with all the ions(calcium, magnesium, silica, sulfate, etc.) removed from the water.
