A boiler water treatment programâs primary function is to keep heat transfer surfaces (steam-generating and associated tubes) free from scale and deposition. The second function is to inhibit corrosion. Boiler deposits are problematic because they typically contain undesirable levels of metal oxides, mineral scale, sludge, or various combinations. Corrosion generally occurs because of excessive levels of dissolved oxygen, but can also develop under tube deposits.
