When it comes to coliform bacteria, they are mainly found in the feces of warm-blooded animals or humans and are widely present in nature. It serves as an important indicator for water quality monitoring of intestinal pathogenic bacteria. In terms of water quality analysis, it is widely present in the online monitoring of medical wastewater. Because coliform bacteria are an important indicator for judging the quality of water. In this chapter, let’s take a look together at the monitoring issues related to coliform bacteria in water.

In fact, as we have mentioned before, there are various monitoring methods for coliform bacteria, such as multi-tube fermentation and membrane filtration. This article introduces to you a device for 24-hour automatic monitoring of coliform bacteria using the enzyme substrate method. The WECT-900 coliform bacteria online analyzer is a device developed by Hangzhou Moody for monitoring coliform bacteria in water. This instrument is easy to operate, can reflect the entire process monitoring in real time, and can automatically perform quality control and calibration to ensure the consistency and reliability of the test results. This instrument detects the total number of bacteria or the content of coliform bacteria in the sample based on the principle that the light signal changes are directly proportional after the reaction between enzymes and bacterial cultures.

It should also be reminded that coliform bacteria are just one of many water quality analysis indicators. Other indicators such as COD, ammonia nitrogen, heavy metals, biological toxicity, total residual chlorine, total phosphorus, and total nitrogen all need to be tested and qualified before being discharged and used. Of course, the data detected by different industries may vary. Therefore, it is still necessary to choose the appropriate online water quality detection equipment based on the industry itself and the requirements of the environmental protection bureau.
