The water quality of the water we drink in our daily lives is up to standard. However, during its transportation through media such as pipelines, the water quality may be affected, for instance, by sediment and rust. In severe cases, bacteria and pathogens might also be carried. Different bacteria have various effects on human health. In this chapter, the manufacturer of online water quality monitoring instruments will explore with you the active Escherichia coli in water and its monitoring!

Water is indispensable in our daily lives, and the quality of water directly affects our health. It is natural to understand the quality of drinking water.

The Hazard of Escherichia coli! Pathogenic Escherichia coli multiply abundantly after invading the intestinal tract, causing diarrhea. For infants, the elderly, those with chronic wasting diseases, and patients with extensive burns, the pathogen can invade the blood system and cause sepsis. Generally, pathogenic Escherichia coli need to be exposed to a high temperature of 100°C for 1-3 minutes to die.

Online Monitoring Equipment for Escherichia coli in Water

The WECT-900 online analyzer for Escherichia coli in water quality adopts the enzyme substrate method and the international standard approach. Based on the principle that the change in light signal is proportional to the enzyme-bacteria culture reaction, it reflects the total amount of bacteria or the number of coliform bacteria in the sample. The Escherichia coli testing technology is an Escherichia coli detection system based on biosensing technology, which can provide an effective detection means to deal with water supply pollution. The quantity of Escherichia coli in the water sample can be indicated by the degree of weakening of the solution’s light intensity compared with the non-toxic control blank experiment.
