Water quality for boilers

Boiler water treatment is essential to ensure a long useful life free of operational issues, important repairs and accidents. From hard water to soft, it is that which has a high level of minerals, particularly calcium and magnesium salts

  • pH represents acidic and alkaline characteristics in water, thus its control is essential to prevent corrosion problems (low pH) and deposits (high pH)
  • Hardness. Hardness in water mainly quantifies the amount of calcium and magnesium ions present in water, which favor the making of deposits and inlays difficult to remove over the heat transference surfaces of a boiler
  • Oxygen. Oxygen present in water favors corrosion in the metallic components of a boiler. Pressure and temperature increase the speed in which corrosion is produced
