Is ORP relevant to pure water?
ORP is simply a measure of millivolts in a solution that reflect the potential for Redox reactions when the solution comes in contact with another substance. Redox is a well-known chemical term that stands for reduction – oxidation reactions or to make it simple a positive or negative reaction. A negative ORP reading indicates it will promote bacterial growth and a positive ORP reading indicates it will prevent bacterial growth. Both characteristics are needed when dealing with water, for example; when we are dealing with wastewater such as sewage we want to promote the growth of bacteria, therefore we want a negative ORP reading. On the other hand, when we are dealing with drinking water we want to prevent bacteria growth; therefore, we want a positive ORP reading. ORP measurements have become the standard test for municipal water suppliers in recent years and have replaced tests such as chlorine and pH, due to increased accuracy involved in a ORP reading.
