People often take water for drinking casually. Water is essential to human existence, whether from a grocery shop or your kitchen sink. But what happens if you’re near a contaminated water source? Do you attempt to drink or run to another drinking fountain?

You’ve probably never considered the ORP and pH values in your drinking water. ORP is a term you’ve probably heard of, but what does it signify, and what function does it serve in water-quality testing? Please continue reading to learn more about the ORP meter and its uses.

What Exactly Is ORP (Oxidation Reduction Potential)?

The ORP (Oxidation Reduction Potential) of a material measures its capacity to reduce or oxidise another chemical. The electrodes of ORP meters are used to detect it. A positive ORP meter reading shows that the substance is an oxidising agent, whereas a negative reading shows a reducing agent.

Why Is ORP Important?

ORP values describe a system’s relative status in terms of electron gain or loss.

ORP is essential in various wastewater and drinking water applications and processes. ORP values are used in swimming pools, cooling towers, potable water supplies, and other water analysis systems to manage disinfection using chlorine dioxide. The ORP content dramatically influences the life lifetime of bacteria in water. ORP measurement is often used in wastewater treatment systems that utilise biological treatment solutions to remove pollutants.

The Basics Of Reduction And Oxidation

If a material lacks electrons, it will aggressively seek them via the oxidation process chemical change in which another oxidises one substance. Because compounds with positive ORP values seek electrons, they are classified as oxidising agents.

However, electrons with ion excess may afford to lose ions to oxidising agents without becoming destabilised. As a result, they are known as reducing or anti-oxidising agents. Moreover, the more antioxidizing or oxidising a material is, the lower or higher its ORP value (negative or positive).

Why Are ORP Readings Crucial In Water Testing?

ORP is crucial in water testing because it tells whether water is sterilised or polluted depending on its reduction and oxidation characteristics. Water is sanitised with a chemical for consumption, recycling, or skin contact to boost its oxidation potential. Furthermore, it is feasible to assess the efficiency of a sanitising agent and adapt your water treatment strategy by frequently testing ORP levels.

ORP Meter Uses

There are several reasons why one might want to know a substance’s ORP. The most typical use is assessing the chlorinated swimming pool’s water quality. Because the ORP of a substance is impacted by all agents present, an ORP measurement is regarded as more instructive than a pH value only, which only identifies bases (hydroxide ions) and acids (hydrogen ions).

Larger pools often include inline ORP sensors, but smaller backyard pools may need a portable ORP monitor. When chlorine is added to a pool, it uses its electron excess to kill or oxidise potentially dangerous germs. Active chlorine electrons raise the water’s ORP content, neutralising pollutants. A safe ORP value for chlorinated pools and spas is generally between 650 and 750 millivolts (mV).

Moreover, the total ORP measurement for the water steadily drops as time passes and chlorine degrades and loses its oxidation potential. Moreover, although the ratio of sanitiser in the water often correlates with ORP levels, ORP does not assess sanitiser levels; instead, it calculates the total reduction and oxidation characteristics of all agents present.

ORP meters are often used in food processing and water treatment to ensure water is clean enough to recycle or drink, as well as to check water quality in chlorinated pools. Bottled water or contaminant-free tap water will also have a positive ORP level.

Adjusting ORP Levels

ORP levels in swimming pools may normally be regulated by adding additional active chlorine to the water to increase its anti-oxidising capacity. The equilibrium of total dissolved solids (TDS) in liquid in greater water purification systems may be more challenging since it is necessary to generate a more beneficial oxidation state in order to accomplish a more advantageous oxidation-reduction potential.

We are surrounded by water. It is in our bodies, flows via faucets, and flows through seas, lakes, and rivers. While water appears to be the same, each source has its unique pH and ORP values.

If you’re worried about your body’s health, heed the pH and ORP in your drinking water. While soft drinks do not have the same pH as hydrochloric acid, they are not beneficial for the body. Because of their acidic nature, they might lead to free radicals.

Furthermore, litmus paper and ORP meter can tell you everything you need to know about the water or other liquid you take. Whether you want to determine if the water is drinkable, look for a low ORP level.
