Why is TDS the fastest water quality test?

Usually when we drink water, how to make sure that a glass of water is OK to drink? greentest eco 6 Most of the way to judge, are judged from the appearance, smell, in fact, you may unconsciously drink dirty things into the stomach!

So what other ways are there to test it? We can look at how tap water is tested for water quality

Tap water has strict regulations

Tap water is the public facility most frequently exposed to by the general public. radioactive detection Therefore, it is necessary to maintain a good quality in both washing and daily water use in enterprises. Therefore, we can see that tap water has a variety of inspection items, from bacterial standards and chemical standards such as pesticide, organic matter and heavy metal detection, which means that China needs to pass these strict tests. Only in order to ensure the safety of everyone's water.

Testing complex instruments are huge

In these tests, it takes two to three days just to get a bacterial count from the culture. radiation detectors for sale However, metals are atomic absorption spectrometry. Each type of testing project has its own testing instruments and methods,

For each test, the content needs to be analyzed by special instruments. The price of each instrument is quite high, and it also takes a lot of time to test. So tap water or drinking water is also sampled.

Water quality inspection has strict inspection methods, and the price is high, so what is the way for ordinary people to quickly test the water quality and ensure safe drinking water?

Water quality can be easily determined by using TDS tests. What is TDS?

TDS stands for the total solids dissolved in water, and the simple way to understand it is that when we evaporate water by heating it, the material left behind is the "total solids content" of the water, but we can only know how much it contains (mg/L). There is no way to know exactly what we are studying in it (for example, whether it is a mineral or a suspended matter).

The higher the TDS, the higher the total solid content in water. The current standard for tap water is 500 parts per million, high-grade mineral water is generally between 3 and 400 parts per million, and the industry's recognized standard for raw water is 40 parts per million, so. The TDS value of mineral water is high, and the TDS value of raw water is also high. In such a gray area, can the TDS value be used as a testing standard?

Yes, as long as the reverse osmosis water purifier, let's review, reverse osmosis filtration level can remove substances above 0.1nm, almost can reach the state of pure water. At this time:

By removing all impurities from the water, the TDS value can be used as a standard, no longer a gray area, and can even be used as an indicator of whether the reverse osmosis water purifier is working properly.

Once the purification rate is found to be significantly reduced, it indicates that the reverse osmosis membrane has been damaged, and the filter element needs to be replaced to maintain the purity of the water.
