When testing water quality samples, it was found that there were coliform bacteria in the water. What does this indicate? How can one know its content in water and whether it will cause harm to the human body? Don’t worry! Let’s get to know them one by one!

If coliform bacteria are found in the tested sample, it is obvious that the water sample has been directly or indirectly contaminated by feces, because coliform bacteria exist in the intestines of humans or animals and are then excreted from the human body through feces.

So, since the human body itself contains coliform bacteria, does this mean that water contaminated by coliform bacteria will not cause harm to the human body? Of course not! If the coliform bacteria in the body exceed the body’s tolerance, it is very easy to cause extraintestinal infection. If they leave the intestine, they may also cause some diseases such as urethritis and cholecystitis. If the situation is more serious, it may even cause sepsis. One more point, causing diarrhea is also one of the conditions.

So how can we know if the coliform bacteria in the water exceed the standard? At this point, of course, “it” is indispensable – the WECT-900 Coliform Bacteria Online Analyzer. This instrument adopts a detection system based on biosensing technology. During the process, enzymes and bacteria become proportional after the culture light signal, thereby reflecting the quantity of coliform bacteria in the sample. This instrument is mainly used in the medical wastewater online monitoring.
