One of the main factors that determine water safety is the oxidation-reduction potential of the water, abbreviated as ORP. ORP indicates how a given water sample is capable of either giving off or taking in electrons as a part of a chemical reaction, which basically shows its ability to deactivate contaminants such as bacteria and those of organic nature. The knowledge about ORP is essential in the preservation of safe and healthy water intended for drinking, recreational activities or hydroponic systems.

1. Understanding ORP

ORP is measured in millivolts (mV) and shows the equilibrium between oxygen and hydrogen sources in water. High positive ORP indicates that the water has a strong oxidizing potential, which in turn makes it easier to get rid of the microorganisms that are harmful to the human body. On the other hand, negative values point to a reducing environment that, as a result, may cause bacteria and algae growth. ORP control is an instant way to check water quality and a valuable aid to the users in determining if the level of disinfection is enough.

2. ORP and Disinfection

An important use of ORP measurement is the assessment of the working capacity of the disinfectants, for example, chlorine, ozone, or bromine. Typically, a higher ORP value will suggest that the water is capable of killing germs in a more efficient way. In the case of swimming pools, hot tubs, or potable water installations, it is considered vital that the ORP level be balanced within the advised limits. 

3. ORP in Different Water Systems

ORP has a wide range that keeps it useful in various water applications. In aquaculture and hydroponics, it is used to maintain suitable conditions for the growth of plants and fishes. In potable water, it plays a role in giving a picture of the chemical balance and the control of contaminants. In the case of natural water resources, ORP monitoring can point out pollution incidents or changes in the chemistry of water. 

Conclusion

ORP indicates how effective water is in killing germs and if it is safe to use in general. Thus the preventive measure and maintenance of a healthy water system are allowed with comprehension and control of ORP. For on-the-spot and easy measuring of ORP with pH and other parameters, the Yewhick digital water tester is a perfect one-take trusted by both households and nature lovers.
