Boiler Water Quality

Alkalinity is defined as water capacity to neutralize acid, or the quantity of anions in water which can neutralize hydrogen cations. Composer alkalinity water are bicarbonate anion (HCO 3-), carbonate (CO 3 2-) and hydroxide (OH-).Borate (H 2 BO 3-), silicate (HSiO 3-), phosphate (HPO 4 2-and H 2 PO 4-), sulfide (HS-), and ammonia (NH 3) also contribute to alkalinity.
