What does ppm value represent for water of water purifier?

Ppm is a kind of soluble substance in water, which is called salt and mineral. The PPM value of drinking water in China is required to be within 50, and the World Health Organization is required to be within 30.
If the filter element is discharged correctly after the water purifier is installed, and there is no water leakage when the machine pipeline is inserted in place, the PPM value is still high. At this time, it may be that the RO membrane wire is damaged, or the water pressure is too high to support the internal membrane wire or the internal membrane wire is broken in the production process.
In this case, the RO membrane cannot be well filtered, resulting in a high ppm value. In order to determine whether it is a problem of RO membrane, we can find an original membrane for testing, and effectively control the water pressure.

matters needing attention:
1. After the water purifier is used, the ultrafiltration membrane filter element shall be kept in a wet state. If the ultrafiltration membrane filter element is dried, the water yield will drop sharply and cannot be recovered.
2. Do not use the water purifier for more than three days. When it is used again, flush the water purifier for 2-5 minutes until the water in the water purifier is drained.
3. When the tap water is out of water, please turn on the drain tap to drain the sediment and rust in the tap water pipe before turning on the purification tap to use the purified water.
4. The total water yield of the water purifier is related to the water quality of the water inlet of the water purifier. If the water quality of the water inlet of the water purifier is good, the total water yield will rise. Otherwise, if the water quality of the water inlet is poor, the total water yield will fall and the service life of the corresponding filter element will be shortened.
5. When the water purifier is used, the water purifier is often washed, which can effectively extend the service life of the water purifier.
