Drinking water pathogen microbial infection will directly harm human health, its intermediate water infectious disease is harmful to human health disease, in order to solve the microbial pollution in drinking water, water quality online monitoring is very important! What is the purpose of monitoring E. coli in drinking water?

Under normal circumstances, unpolluted water bodies are free of pathogenic microorganisms. Once contaminated, various pathogens enter the water body with human and livestock excretions and other pollutants, resulting in the spread of waterborne infectious diseases. In the human gut, there are mainly E. coli, streptococcus faecalis and anaerobic bacillus and other bacteria, these bacteria will enter the water body with the excrement, so that the number of E. coli in the water body is large, while monitoring E. coli is to reflect the degree of pollution in the water body is multiple, so as to judge the specific situation of water quality.

What Methods and Instruments are Used to Monitor the Water for E. coli?

Hangzhou Modi-Tech has produced an enzyme substrate method for WECT-900 Escherichia coli online analyzer, which is an international standard method, and the light signal change is proportional to the principle of enzyme and bacterial culture reaction, which can reflect the total number of Escherichia coli in the sample. Escherichia coli detection technology, which is based on biosensor technology of Escherichia coli detection system, is an effective response to water supply pollution detection means. The number of E. coli in water samples can be indicated by the degree of light intensity weakening of the solution and the comparison of non-toxic control blank test.

In order to drinking water enterprises in the production and processing process, E. coli does not exceed the standard, it is necessary to strengthen the monitoring and control of health and safety in the production process. At the same time, disinfection should also pay attention to, if the use of chlorine-containing disinfectant, this time must pay attention to the change of the total residual chlorine in the water, so as to avoid the total residual chlorine exceeding the standard to the human body harm! (RCl900 total residual chlorine online analyzer is used to monitor the total residual chlorine content in water in real time)
