How to correctly avoid the hidden dangers of the ultrapure water machine?

      Ultrapure water machines are often used in the purification of laboratory water, which can remove impurities, salt ions, bacteria, viruses, etc. When there is a power outage in the laboratory or a large amount of water is used in a short period of time, the water storage tank can meet the temporary water demand. However, due to user habits and many objective factors, there are certain hidden dangers in the ultrapure water machine equipped with a water storage tank.

The ultrapure water storage tank has the following hidden dangers:

1. Deterioration of water quality

The water storage tank is prone to air leakage after a period of use, resulting in insufficient water pressure, and there will always be some pure water left in the water storage tank. This part of the water becomes stagnant water that cannot flow. Stagnant water tends to breed bacteria and form biofilms. It not only reduces the water quality, but also easily leads to biological poisoning of the back-end purification unit.

2. Secondary pollution

Some water storage tanks are made of cheap industrial plastics, which not only have poor airtightness (impurities in the air enter), but also easily dissolve pollutants. The inside of the box is uneven and easy to hide dirt. The overflow port is connected to the underground pipeline, which is not conducive to the maintenance of water quality.

3. Safety hazard

The water level sensing device used in some water storage tanks makes the water and electricity cannot be separated, and there are certain safety hazards.

4. Not easy to disinfect

Due to the small diameter of the water inlet and outlet, it is difficult for users to carefully clean and disinfect it. This makes the storage tank a breeding ground for bacterial growth and worsening water quality.

5. Damaged consumables

As the pressure of the water storage tank increases, the quality of the pure water will gradually deteriorate, which will lead to a sharp decrease in the exchange capacity of the ultra-purification column and a shortened service life; the output of pure water will gradually decrease, which will cause damage to the RO membrane.

In order to avoid hidden dangers such as deterioration of water quality, secondary pollution, and damage to consumables of ultrapure water devices, users should pay attention to the following points:

1. Material of water storage tank

Choose a water storage tank with good material, good airtightness, and air filtration function (equipped with an air filter). While ensuring stable water pressure, it reduces air pollution and impurity dissolution.

2. The location of the water storage tank

Do not place the water storage tank in direct sunlight, otherwise it is easy to cause microbial contamination, and even algal blooms.

3. Install sterilization device

Once microorganisms such as bacteria are produced in the water storage tank, the entire system will be polluted. It is recommended to install ultraviolet sterilization devices in the water storage tank and pure water pipeline to completely kill microorganisms.

4. How to get water

In order to obtain high-purity water, it is advisable to use it immediately in daily use. Pay attention to the water after the initial water is drained, and avoid the generation of air bubbles when taking the water. If there is a need for water storage, the pure water storage time should be controlled within 24 hours. If there is no water demand for a long time, the pure water in the water storage tank must be drained.

The above are the common hidden dangers and avoidance methods of ultrapure water machine water storage tanks, hoping to help everyone use this product better.
