Substances composed of oxygen in the human body or the natural environment are called “reactive oxygen species”, which are the general term for substances with active oxygen-containing properties. But it can also be used as a disinfectant to disinfect different kinds of sewage and wastewater! During the process of disinfecting wastewater and sewage, oxygen and water are generated after the action, which is different from chlorine-containing disinfectants.

Take medical wastewater for example! Hospitals are places where disinfectants are frequently used. Besides chlorine dioxide disinfection, active oxygen disinfection is also a commonly used disinfection method in hospitals. However, we should understand that no matter which method is used for disinfection, the amount of disinfectant added to the wastewater must be appropriate. If it is too little, it is impossible to completely eliminate viruses and bacteria. These disinfectants themselves also have harmful effects. If used in excessive amounts, they can cause certain harm. Take active oxygen for example. It cannot be seen until it reaches a certain disinfection effect. Therefore, the staff need to extend the release time and amount of active oxygen.

So how can we know if the active oxygen in the sewage is low and has not reached the threshold? This can monitor the concentration of active oxygen in sewage in real time through instruments. This way, the changes in the concentration of active oxygen in the water can be understood in a timely manner! Hangzhou Moody has a product called “ROS900 Active Oxygen Online Analyzer“, which uses the induced fluorescence method or colorimetric method. Through this method, the concentration of active oxygen in wastewater can be detected, and then analyzed to determine whether the active oxygen in the wastewater is too low.

Remember! In fact, whether it is active oxygen disinfection or chlorine disinfection, the amount should be moderate during the disinfection process to fully exert its effect!

Of course, the detection of active oxygen in water is only one indicator after sewage treatment. Besides, there are many other indicators that need to be tested one by one by the staff. Of course, the specific indicators to be tested depend on the water quality conditions. In conclusion, doing a good job in online water quality monitoring is an important link in the sewage treatment process!
