What are the requirements for the inlet water of the ultrapure water machine?

      Laboratory water requirements are very high, and the quality of water quality is often related to the success or failure of experiments. Therefore, in order to reduce unnecessary errors and losses, ultrapure water machines are often used in laboratories to prepare pure water. It is necessary to understand and follow the water inlet requirements of the laboratory ultrapure water machine when using this equipment.

In order to ensure the water production efficiency and purification effect of the ultrapure water machine, the water inlet of the system needs to meet certain conditions. Taking urban tap water as an example, the specific requirements are as follows:

1. The quality of the influent water must meet the relevant requirements of the "Daily Water Specification", and the water temperature should be kept between 5 and 45 °C.

2. The water supply pressure is 0.1~0.4MPA, and the conductivity is less than 200us/cm

3. Turbidity<0.5NTU, residual chlorine<0.1ppm, TOC<2.0ppm

4. Total organic biomass <5ppm, bacterial content <100000cfu/ml

5. If the content of iron and manganese in the influent water is high, it is recommended to install a manganese sand filter.

6. The influent water quality is greatly affected by the region, and the south is generally better than the north. In order to make the TDS value of the influent water not higher than 300, a water softener can be selected appropriately.

7. If affected by geological and other factors, the influent water body contains a large amount of sand and mud, it is recommended to be equipped with a pretreatment device.

The above are the water inlet requirements that need to be met when using the ultra-pure water machine, and the application scope of this equipment involves hospitals, university scientific research, quality inspection units, chemical plants, pharmaceutical factories, water quality monitoring centers, animal husbandry, water plants, and disease control centers. , seed monitoring station, battery factory, LCD screen factory, precision circuit factory, dust-free product production and so on.
