  • Chlorine Concentration Adjustment Calculator for Water

    This calculator can be used to adjust the chlorine concentration of water to disinfect it for drinking and also for other applications Typical levels of free chlorine or residual chlorine in drinking water are 0.22.0 mg/L though levels can be as high as 5 mg/L Chlorine that is added to water is consumed first to become combined chlorine before it can emerge as free chlorine.
