Matters needing attention when replacing parts of ultrapure water machine

      At present, ultrapure water machines are widely used in hospitals, laboratories, universities, testing centers, industry, CDC, environmental monitoring, pharmaceutical industry, electronics industry and other fields. In the process of use, there are inevitably some parts that need to be replaced regularly, so the replacement parts of common parts of ultrapure water machine and the points to pay attention to:

1. Preprocessing unit

The pretreatment of ultrapure water machine is composed of activated carbon filter element, quartz sand filter element and softening filter element. The use time of the pretreatment unit is generally about 3 to 6 months. The specific use time needs to be judged according to the daily water consumption of the user, and The pretreatment unit is in front of the reverse osmosis membrane, and its main function is to filter the large particles in the water and the residual chlorine in the water, which can prolong the service time of the reverse osmosis membrane and play a good protective role.

2. Precision filter

The precision filter element mainly filters large particles such as sediment in the raw water. If the filter element is brown, it means that the filter element cannot be used. The life of the precision filter element is generally 3-6 months. If the original water has a lot of sediment, its life is short If there are less particles such as sediment, the life span will be slightly longer.

3. Reverse osmosis membrane

In the ultra-pure water machine, although the various accessories cooperate with each other to achieve excellent effluent quality, the reverse osmosis membrane has a very high position in it. The reverse osmosis membrane used in the pure water machine is imported Dow reverse osmosis membrane. , the desalination rate reaches 99%. The life of the reverse osmosis membrane is 12-18 months, which is mainly determined by the customer's water consumption, so the user must choose the matching specification when purchasing.

4. Ultra-purification column

The purification column is also known as the ultra-purification column. The function of the ultra-purification column is through the principle of ion exchange. The ultra-purification column has a very strong ability to remove ions in water. Generally, the quality of water quality is determined by judging the number of positive and negative electrodes for ions in the water. The life of the column is represented by the resistivity online. Below a certain resistance, it means that the purification column has expired. It is more intuitive, and its life is mainly affected by the customer's water consumption.
