Online Redox Potential ORP Probe for Drinking Water

In 1971, the world Health organization stipulated that the ORP value of drinking water should be 650mV(platinum/calomel electrode) or 700mV(platinum/AgCl electrode). ORP value refers to the oxidation-reduction potential, which is a measure of the redox capacity of water. In the monitoring of drinking water, the ORP value is a very important parameter, which can reflect the redox status of the water body and determine whether the water quality meets the standard. Generally speaking, the higher the ORP value, the more oxidants are in the water, and vice versa, which means there are more reducing agents. In the drinking water treatment process, the ORP value of raw water needs to be measured, because the ORP value describes the concentraction ratio of reducing and oxidizing substances in the water. These include nitrates, sulfates and manganese oxides. A low ORP value means a higher risk of microbial contamination. The ASR300V online ORP Sensor developed and produced by Delfino has a measurement range of -1500mV-1500mV. It can continuously monitor the ORP value of water quality in real time. When disinfecting drinking water, the dosage of oxidants such as chlorine is based on the ORP measurement value, so choose a reliable, accurate ORP sensor is important to avoid underdosing or overdoing disinfectant. When the dosage of drinking water disinfectant is insufficient, it cannot completely kill bacterial; when it is excessive, it will accelerate the wear of system components, requiring additional treatment to reduce the chlorine concentration to maintain the health and safety of drinking water.

Why is ORP used as a standard indicator in drinking water disinfection?

1. In drinking water treatment, the ORP value can better reflect water quality than the total number of E.coli indicators. The ORP indicator takes into account a variety of chemical factors that can affect the overall sterilization effect, such as pH, residual chlorine, cyanuric acid concentraction, organic load, and nitrogen load in the water, giving a simple, reliable, and accurate reading on the disinfectant and water quality that can avoid a series of time-consuming and expensive chemical and bacteriological tests are performed to obtain test results in one go. In particular, ORP can detect the effective oxidizing ability of disinfectants such as chlorine, bromine, and ozone. In addition, ORP is suitable for all standard disinfectants such as chlorine and bromine and other optional disinfectacnts such as ozone, potassium permanganate, metal ions and UV system.

2. ORP is easy to detect. You can use an online ORP probe to continuously monitor, and the ORP controller to display the water quality and even start or stop the chemical dosing device to maintain water quality.

The ORP probe plays an indispensable role in the drinking water treatment process. When paired with an online ORP controller, it can also realize display, control and output functions.
