WebA Controlled Phosphate Program – Boiler Water Treatment Chemical Program In most of these types of systems, precipitation programs are used for scale control. The most commonly used precipitating agents are carbonate and phosphate. Using carbonate, the hardness is precipitated as calcium carbonate and magnesium hydroxide. WebBoiler water is treated to prevent scaling, corrosion, foaming, and priming. Chemicals are put into boiler water through the chemical feed tank to keep the water within chemical range. These chemicals are mostly oxygen scavengers and phosphates. The boiler water also has frequent blowdowns in order to keep the chloride content down.
