HIGH POSITIVE ORP = DISINFECTING POWER A high positive ORP is desired in sewage treatment, swimming pools and spas, because the higher the ORP, the more oxidation will occur, thus killing the bacteria and unwanted pathogens, by stealing electrons from the bacteria’s DNA, cell membranes and proteins.1Chlorine is added to water because it has a high ORP…
ORP Meters simple explanation Oxidation-reduction potential can be measured using a potentiometer (voltmeter) or an ORP meter.1 Water produced from electrolysis (ionized water), as well as other forms of hydrogen water, exhibit a negative ORP.2 But what is the meter actually measuring? And how does it work? Basically* you have different chemical species in the water that can either undergo oxidation or…
OXIDATION-REDUCTION POTENTIAL ORP BASICS* One of the characteristics of water containing dissolved molecular hydrogen (such as ionized water) is that it exhibits a negative oxidation-reduction potential (O.R.P.).1Chemical reactions occurring in an aqueous solution are called redox reactions.2 The ORP measures the capacity of a solution to either release or accept electrons from chemical reactions. The ORP value, much like pH,…
HALF-REACTIONS As explained previously, ORP is measured in volts and informs us of a solution’s oxidizing or reducing potential.1 An ORP probe measures the voltage difference between redox couples in accordance with their half reactions2 (see table 17.1 below). For example, the first redox couple fluorine (F2) is a strong oxidizing agent. If you measured the voltage difference between F2 and…
