  • Water Treatment (Steam Boilers) | CleanBoiler.org

    Primary indicators of boiler water treatment are pH, TDS (Total Dissolved Solids), TSS (Total Suspended Solids) and hardness. Water pH. Water pH is a measure of its relative acidic or alkalinity. A neutral level is pH = 7. A number lower than 7 is acidic and higher than 7 is alkalinic (caustic). Both extremes are corrosive to boiler metal.Learn More
