Orp In Pool Water

It is used to test both drinking water and swimming pool water to determine how effective oxidizers are in the water and therefore how safe the pool is to bathe in.

Orp in pool water. For chlorinated pools and spas a safe orp reading is usually between 650 millivolts mv and 750 mv. Oxidation reduction potential orp measures the oxidizing properties of any sanitizer present in the water. Orp is determined by using a high quality orp probe and meter. Oxidation reduction potential is.

It is a proven measurement mandated for commercial pool sanitization now available for residential pools. In the pool industry chlorine is usually the primary oxidizer and contaminants like metals ammonia and non living organics are the targets of oxidation. Unlike most home test processes orp is not fooled by the effects of ph tds total dissolved solids and other factors. Alkaline ionized water is an anti oxidizing agent as it has a negative orp value and it is able to donate extra electrons to neutralize the harmful effects of free radicals on the body.

Orp oxidation reduction potential measures the oxidizing capacity in water. Oxidation reduction potential often shortened to the acronym orp is a measurement of chlorine s ability to oxidize contaminants in the pool water. The following video explains orp and shows the orp level of different kinds of water. Orp stands for oxidation reduction potential.

Orp is a measurement in millivolts mv of the water s potential for oxidizers to steal electrons from another substance. But pool operators especially novices often misunderstand orp as an actual measurement of sanitizer. Oxidation reduction potential or orp is a measure of the oxidizing capacity in water or more simply put the cleanliness of the water and its ability to break down contaminants. Orp or oxidation reduction potential is a term that you may have heard in relation to managing the water quality in your pool but what does it actually mean.

The unit of measurement of orp is millivolts mv. Orp was adopted in 1971 by the world health organization as a standard test for drinking water treatment and has been used to improve pool sanitation for over 40 years. Oxidation reduction potential orp redox measures the rate of oxidative disinfection caused by the addition of the effects of all oxidants in the pool water. Most other types of water are oxidizing agents as their orp is positive.

Orp is probably the most common method used by chemical controllers to measure sanitizer level and the most inexpensive type of system. Oxidisers mainly disinfectants consume electrons while reductants mainly contaminants donate electrons.
