    2014-10-6 · High-alkalinity phosphate treatment is most commonly employed in low-pressure systems where soft water makeup is employed. It features high-pH boiler water in the range of 10.8 to 11.4. This is optimum for formation of a protective oxide on carbon steel, and at this pH, hardness precipitates are less adherent than those formed at lower pH.
