The total number of colonies actually refers to the total number of bacterial colonies that grow under certain conditions. It is relatively common in medical wastewater. Therefore, the total number of colonies is an important indicator for the online monitoring of medical wastewater. As for the methods for monitoring the total number of colonies in water? In fact, there are many types, such as multi-tube fermentation method, membrane filtration method, enzyme substrate method, etc. In this chapter, we are going to introduce to you the monitoring method of the WECT-900 online water quality colony count monitor produced by Hangzhou Modi – the enzyme substrate method.
The total number of colonies in water was monitored by the enzyme substrate method. First, when the reflective signal changes of the enzyme and bacterial culture reactions are proportional, at this point, the total number of colonies in the water can be determined. This technology is a total colony count detection system based on biosensing technology, providing a means of monitoring water pollution. Additionally, it can represent the total colony count content by comparing the intensity changes of solution light and non-toxic control blank tests.
This online monitoring instrument is easy to operate, can reflect the entire process monitoring in real time, and will dynamically display the reaction curve of the detected items. Automatic quality control calibration can ensure the consistency and reliability of monitoring results. Users can program the monitoring parameters by themselves. It is also applicable to the automatic start of the cycle detection mode for problem samples in different occasions. At the same time, it has the features of warning of power failure and resuming normal working state after power is restored.
Overall, the enzyme substrate method for detecting the total number of colonies in water is relatively advanced and has certain advantages over the other two methods. Of course, which method to choose still depends on the customer’s own needs!
