Coliform bacteria are included in the monitoring indicators for both drinking water and medical wastewater. So what exactly is the purpose of monitoring coliform bacteria in wastewater? Let’s take a look.
As mentioned in this article, coliform bacteria are widely distributed, mainly existing in the feces of warm-blooded animals and widely present in nature. They are normal flora in the intestines of humans and other warm-blooded animals, and do not naturally occur in pristine water bodies. Therefore, the presence of coliform bacteria indicates fecal pollution of the water environment. In wastewater, monitoring coliform bacteria can determine whether the water is contaminated by feces — this is the primary purpose of monitoring coliform bacteria in wastewater.
The WECT-900 Online Coliform Analyzer adopts a monitoring system based on biosensor technology. The degree of light intensity weakening in the water sample due to coliform bacteria is compared with a non-toxic control blank. The total number of coliform bacteria in the sample is reflected through bacterial cultivation.
Key features of the analyzer include automatic calibration and quality control, ensuring consistency and reliability of test results. It also supports real-time full-process monitoring and is simple to operate.
In addition, coliform bacteria were initially used in water quality monitoring as indicators of intestinal pathogenic bacteria. Today, they are widely used not only in water quality testing but also as indicator bacteria for food hygiene quality inspection.
