pH Treatment | CleanBoiler.org

Alkalinity is a measure of the bicarbonate (HCO3), carbonate (CO3) and hydroxyl (OH) ions in the water. pH and alkalinity ratings are NOT the same and are NOT proportional. pH is rated on the Scale and alkalinity is measured in parts per million (ppm). A typically recommended alkalinity rating is 140 – 700 ppm for boilers operating below 300 psi.

Unichem - Boiler Chemical - Alkalinity Builder by Unichem

Typically, as boiler operating pressure increases so does the need for higher purity water. At the same time, water treaters need to maintain a minimum level of OH alkalinity (generally, over 150 ppm as CaCO 3) to prevent scaling tendencies while ensuring excess alkalinity doesn't interfere with other chemical treatment components. In cooling water, treatment professionals aim to control alkalinity (and pH) to …
