Internal Water Treatment

Internal treatment is the conditioning of impurities within the boiler system. The reactions occur either in the feed lines or in the boiler proper. Internal treatment may be used alone or in conjunction with external treatment. Its purpose is to properly react with feed water hardness, condition sludge, scavenge oxygen and prevent boiler water foaming. In a correctly controlled phosphate program, the precipitants are a form of calcium phosphate called calcium hydroxyapatite, and magnesium hydroxide. 

One or more polymers are included in the chemical program. Polymers are long chain organic molecules that adsorb onto sludge particles, and because they are carry a slight negative electrical charge, disperse the particles, preventing them from agglomerating and adhering to the boiler metal, and allowing for their easy removal in the blowdown.
