Free Chlorine Vs Total Chlorine Wastewater. Combined is the chlorine that has mixed with organic matter that has mostly been used up; It’s merely the sum — the total of combined and free chlorine levels in the pool water.

> the free chlorine measurement works best below ph 8.5, while the total chlorine. Methods for determining free, combined and total. Free chlorine is a component of total residual chlorine, the portion of dissolved chlorine gas that is not bonded to any other reactants in water.
Free chlorine is that which is still.
Free chlorine = 1.0 ppm concentration readings ph = 7 ph = 7.5 ph = 8.0 dpd 1.0 ppm 1.0 ppm 1.0 ppm amperometric 1.0 ppm ~0.6 ppm ~0.2 ppm at a ph 8.0 or greater (often the operating range for facilities experiencing problems with dbps), the hocl part of free chlorine concentration is very low (<20%), therefore accuracy of the amperometric > if you have any further questions, please contact a kuntze representative or submit a ticket. It is the difference between the amount of chlorine added to wastewater and the amount of chlorine residual remaining after a given contact time. Free is the chlorine that is ready to fight bacteria and other microbes;
