How to accurately monitor ozone concentration in water treatment applications

Ozone has the characteristics of strong oxidation, easy preparation, easy decomposition, and no residue. It has a very wide range of applications in the modern water treatment industry. In all water treatment applications, the ozone concentration is an important monitoring quantity. How can we accurately monitor the ozone concentration? How to choose an ozone monitor is a headache for many people. Based on years of experience in ozone application, Minstrong hereby provides you with some practical suggestions.

Ozone monitoring is divided into high-concentration monitoring and low-concentration monitoring. Low-concentration monitoring is relatively simple. Under working conditions of no more than 100ppm, chemical sensors can be used directly. This type of sensor is relatively inexpensive and has better accuracy. There are also many manufacturers, and low-concentration monitors have more options. However, if this low-concentration instrument is impacted by high-concentration ozone, it will cause irreversible damage.

So how the high concentration of ozone should be monitored? Ordinary chemical sensors will definitely not work. According to Lambert-Beer law, spectrophotometry is a good method, so the high-concentration ozone monitors above are basically based on ultraviolet spectrophotometers. However, high-concentration ozone monitors have many conditions in terms of installation and use, which often leads to incidents of instrument damage caused by improper installation or use. This kind of instrument is relatively expensive and has caused considerable losses.

The installation of high-concentration ozone monitors usually has two installation processes: series method and bypass method. Before the gas enters the measuring cell, it needs to be dried. After analysis, the ozone gas cannot be directly discharged into the environment and needs to be decomposed by ozone. Destroyer, which decomposes high-concentration ozone into oxygen before it can be safely discharged.

Minstrong focuses on the research and development and production of ozone decomposition catalysts, and has rich practical experience in the decomposition of high and low concentrations of ozone.  Minstrong welcome your inquiry.
