How to perform a simple inspection of water quality at home

Methods for product testing of water quality testing manufacturers:

TDS water quality detection pen: TDS meaning: TDS, the Chinese translation is total soluble solids, that is, the total amount of solids dissolved in water is the total amount of solids dissolved in water, and the unit is mg/liter. The value represents one How many milligrams of total dissolved solids are in a liter of water. In layman's terms, the TDS value represents the content of dissolved impurities in the water. The larger the TDS value, the greater the impurity content in the water. On the contrary, the smaller the impurity content. However, the TDS value is only one of the water quality indicators, which cannot be used to judge the water quality. The standard TDS value of drinking water in the United States is 0-50, and the standard TDS value of the European Union is 0-70. The value of tap water in each city in China can be checked by logging in to each city's water company. Generally speaking, the TDS value is between 0 and 500, which is an acceptable range.

It should be noted that the TDS water quality test pen cannot be used to measure high-temperature water bodies, nor can it be used to measure water bodies with large sloshing; nor can it be used to measure water bodies with high pollution concentrations.

Water quality testing is one of the necessary tasks before water home improvement. It largely determines what water home improvement equipment you need. Generally, water quality testing is done by professional water quality inspection personnel. Before the company comes to install, you can also check the water quality of your own home. It is not difficult. At the same time, you can also determine what type of water treatment equipment is probably needed, and make a good budget for water home improvement.

1. Look: Fill a glass of water with a glass of higher transparency, and look at the light to see if there are any fine substances suspended in the water? Let it stand for three hours, and then observe whether there is sediment at the bottom of the cup? If so, explain The suspended impurities in the water seriously exceed the standard; a water purifier must be used for terminal treatment;

2. Smell: Take a glass of water as far as possible from the faucet, and then use your nose to smell it. Is there a smell of bleach? If you can smell bleach, it means that the residual chlorine in the tap water is too high! A water purifier must also be used for terminal treatment;

3. Taste: Drink boiled water hot, whether it smells of bleaching powder, if you can smell the bleaching powder, it means that the residual chlorine in the tap water exceeds the standard! A water purifier must also be used for terminal treatment;

4. View: Use tap water to make tea, and observe whether the tea turns black overnight? If the tea turns black, it means that the tap water contains iron. Manganese is seriously exceeded, and a water purifier equipped with iron and manganese filter elements should be used for the terminal deal with;

5. Product: Taste the boiled water, is there any astringency in the taste? If so, it means that the hardness of the water is too high, and a water purifier equipped with a softening filter element of ion exchange resin should be used for treatment. The taste of the water after treatment Will be sweeter;

6. Check: Check the water heater at home. If you turn on the kettle, is there a layer of yellow stain on the inner wall? If there is, it also indicates that the hardness of the water is too high. You should also use a softening water purifier as soon as possible to soften it! Note: Water with too high hardness can easily cause scaling of water heater pipes and burst pipes due to poor heat exchange; long-term drinking of water with too high hardness can easily cause people to get various stone diseases.
