Total bacterial count is not only an important indicator for Online Monitoring of Medical Wastewater but also serves as a metric for assessing drinking water quality. Monitoring the total bacterial count in drinking water is used to determine the extent of bacterial contamination and its sanitary quality, i.e., to check whether the drinking water meets hygiene standards, facilitating an appropriate evaluation of water quality.
What causes the total bacterial count in drinking water to exceed standards?
The main sources of contamination during the production of drinking water are primarily insufficient disinfection, followed by secondary contamination during bottling due to bacteria-laden air. Additionally, secondary cross-contamination from bottling equipment and materials can occur. Ultimately, secondary contamination during the post-processing stage is the fundamental reason for excessive total bacterial count in the product.
The Hangzhou Mudi WECT-900 Online Total Bacteria Count Monitor is used to conduct real-time monitoring of the total bacterial count in drinking water to check whether it exceeds standards. This system employs a biosensor-based detection method for total bacterial count, which compares the degree of attenuation of concentrated liquid absorbance with a non-toxic blank control test to indicate the content of total bacterial count in the water. It complies with China’s relevant drinking water standard, GB 5749-85, which stipulates that the total bacterial count should not exceed 100 cfu/g (mL), using the enzyme substrate method. The instrument is easy to operate and is a fully automated control device, capable of automatic zero adjustment and automatic calibration.
It is important to understand that the microorganisms causing water unsafety are mainly due to the presence of pathogenic bacteria, toxin-producing bacteria, and corrosive bacteria, among others. Therefore, the total bacterial count alone may not adequately reflect the safety of the water. The key is to control harmful microorganisms, and the indicators for water quality monitoring are not limited to total bacterial count. There are also other conventional parameters, such as total nitrogen, total phosphorus, COD, and total residual chlorine.
