COD is actually a common indicator in wastewater monitoring. So, is the active oxygen mentioned in this article the same as COD? The manufacturer of online water quality monitoring instruments will give you a simple analysis.

COD measures the amount of reducing substances that need to be oxidized in water through a chemical method, and is also called chemical oxygen demand. It is not the active oxygen in water, but the amount of oxygen required to eliminate pollutants. As for active oxygen, it is a substance containing oxygen and having active properties formed by oxygen in the body or in the natural environment. Why monitor the active oxygen in wastewater? Let’s continue and you will understand!

In fact, it should be the detection of active oxygen disinfection for hospital wastewater. We know that chlorine-containing disinfectants are just one of the “props” of disinfection. In fact, there are ozone disinfection, ultraviolet disinfection, and the active oxygen disinfection mentioned in this article, etc. We know that when using chlorine-containing disinfectants for disinfection, it is necessary to do a good job in the total residual chlorine detection. Of course, active oxygen is no exception. The main purpose of monitoring active oxygen in wastewater is to control and judge the water quality disinfection situation. Not only to convert harmful substances in the wastewater into harmless substances, but also to control the dosage of active oxygen properly to avoid causing harm due to excessive active oxygen.

Active oxygen disinfection is a disinfectant mainly composed of adding potassium persulfate and salt as the main components. The disinfectant is stored in powder form and then added in solution form. It is mainly used for the disinfection of drinking water and medical wastewater, etc.

The Hangzhou Modi ROS900 Active Oxygen Online Analyzer is used to monitor the active oxygen in wastewater in real time. It is a fully automatic operating instrument.
