In boiler systems, that environment includes hot water with a low pH or slightly acid condition and some degree of oxygen entrainment. Those conditions are ideal for corrosive action. Removal of carbon dioxide and oxygen from boiler feedwater is essential to preventing boiler-system corrosion.

of the makeup water. For example, the makeup water chloride concentration is 10ppm so the boiler chloride concentration must never exceed 100ppm. The only way to control the cycles of concentration in boilers is to remove (blow down) some of the highly concentrated boiler water. Makeup water replaces blow down and dilutes the remaining boiler
