In recent years, Online Coliform Analyzers have been incorporated into the standard testing protocols for drinking water. Their core function lies in the quantitative determination of microbial indicators, particularly the concentration of coliform bacteria. The WECT-900 model, manufactured by Hangzhou Modi, utilizes the enzyme-substrate method: the enzymatic reaction induced by bacterial metabolism generates a light signal whose intensity is proportional to the bacterial count, thereby enabling the quantification of total bacteria in the sample.
This Water Quality Analyzer is based on biosensor technology, providing an efficient approach for detecting water contamination events. The coliform concentration in water samples is determined by comparing the reduction in solution light intensity with that of a non-toxic blank control. Key features include user-friendly operation, real-time monitoring throughout the entire reaction process, programmable detection parameters, and automated cyclic testing capabilities adaptable to diverse scenarios and sample types. With a detection time of less than 12 hours, it supports both continuous monitoring and time-interval-based measurements. Post-detection, quantitative analysis is performed to evaluate water quality based on the generated data.
Coliform bacteria, also referred to as thermotolerant coliforms, primarily colonize the intestinal tracts of humans and other warm-blooded animals, and are excreted through feces. Water sources contaminated with fecal matter often contain high levels of coliform bacteria. If coliforms are detected in drinking water, consumption of such water may lead to human poisoning or the outbreak of infectious diseases. Thus, water quality monitoring for drinking water must not be underestimated.
Additionally, this Online Coliform Analyzer is not limited to Drinking Water Monitoring; it also plays a critical role in medical wastewater surveillance. In complex settings such as hospitals, where a variety of viruses and bacteria are present, the detection of coliform bacteria serves as an indicator for assessing the total bacterial load in the wastewater.
