Date:2024-07-11 Browse: 15

When it comes to drinking water, it is a water source that is very close to our life, and a mistake is very harmful to the human body! So water quality monitoring is our indispensable link! So what are the main monitoring items for drinking water? What instruments are needed for monitoring?


China’s “drinking water sanitation standards” GB5749-2006 drinking water routine testing items 38, detection indicators:

1) Microbial indicators (4 items) : including total coliform, thermostable coliform, Escherichia coli, and total number of colonies;

2) Toxicological indicators (15 items) : including arsenic, cadmium, chromium, lead, mercury, selenium, nitrate, bromate, formaldehyde, chlorite, chlorate;

3) Sensory properties and general chemical indicators (17 items) : including chroma, turbidity, odor and taste, visible objects, pH, aluminum, iron, manganese, copper, zinc, chloride, sulfate, total dissolved solids, total hardness, oxygen consumption, volatile phenols, anionic synthetic detergents;

4) Radioactivity index (2 items) : including total α radioactivity, total β radioactivity.

As for the instrument used is not a single, depending on what parameters the user needs to monitor, a parameter has its corresponding instrument, for example: the above microbial indicators used in the instrument is the “water quality Escherichia coli online analyzer“, the parameters of the toxicity indicators are more, in addition to the use of heavy metal online monitoring instruments, there are some special parameters of the monitor. All in all, it is to look at the parameters provided by the user to determine which instruments need to be used!
