Chlorine and ozone are the most common disinfectants used in the water and waste water industry. Oxidation- Reduction Potential is the parameter commonly used to measure the REDOX reactions and it is the only practical method we have to electronically monitor disinfectant's effectiveness.
pH is the measure of the hydrogen ion concentration in a liquid. pH measures the acidity or alkalinity of a liquid. The pH scale is logarithmic and runs from 0.0 to 14.0 with 7.0 being neutral. Readings less than 7.0 indicate acidic solutions, while higher readings indicate alkaline or base solutions. Chlorine and Ozone are the most common disinfectants used in the water and waste water treatment industry. Oxidation-reduction potential (ORP) is the parameter commonly used to measure REDOX reactions and is the only practical method we have to electronically monitor disinfectant effectiveness.
