: : 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?)
: : thanx.
: 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.
1. betz hand book: any more info on publishers etc.,?any sites where i can get the same info?
2. DI water can pull out metal from the boiler surface is what i read in one pf the forums.how true is this? using water produced from sea water(like in a ship) is it same as using DI water?
