The number of Escherichia coli groups in water refers to the actual value of Escherichia coli groups contained in 100ml water samples, expressed by the number of the nearest Escherichia coli. Under normal circumstances, the intestines of animals are mainly E. coli groups, streptococcus faecalis and other bacteria, these bacteria will enter the water source with human and animal excrement, when the number of E. coli groups reaches a certain amount, the water source is polluted, causing harm to the human body and ecological cycle is certain! Therefore, the monitoring of E. coli groups in drinking water is very necessary!
Harm
E.coli are normal resident bacteria in the gut, and a small percentage of them cause disease under certain conditions. E. coli serotypes can cause human or animal gastrointestinal infections, mainly caused by specific fimbrial antigens, pathogenic toxins and other infections, in addition to gastrointestinal infections, but also cause urinary tract infections, arthritis, meningitis and septic infections.
How to Monitor
As for the monitoring methods, there are many, multi-tube fermentation, filtration membrane method and so on. The WECT-900 Escherichia coli group online analyzer produced by Hangzhou Moody uses the enzyme substrate method. Using the international standard method, the principle that the light signal change is proportional to the reaction between the enzyme and the bacterial culture reflects the total amount of bacteria or coliform bacteria in the sample. How it works: E. Coli Test technology is a biosensing technology based E. coli detection system, which provides an effective means of detection against water supply contamination. The number of E. coli in water samples can be indicated by the degree of weakening of the light intensity of the solution compared with the non-toxic control blank experiment.)
In fact, there are many industries that need to monitor water quality problems, such as sewage treatment plants, industrial wastewater discharge and other places are tested by water quality monitors. But the water quality parameters of different industries will be different!
