Sodium - Water Quality Parameter Overview and Products | Hach

Sodium levels lower than 1 ppb are commonly found at the mixed bed output, both in the steam circuit and in the condensate. Levels of 0 - 10 ppb can be found under normal working conditions at the cation exchangers output, but this can become as high as 100 ppb at the resin exhaustion or in boiler water.
