Let's talk about ultrapure water...

1. How long can the pure water and ultrapure water taken by the ultrapure water mechanism be stored?

How long can the pure and ultrapure water from the ultrapure water mechanism be stored? Because the production speed and efficiency of the ultrapure water machine has been much higher than the traditional pure water production standard, it has become one of the necessary equipment for the preparation of pure water in the laboratory, and the pure water quality that can be produced by different ultrapure water machines is not the same.

The production speed of ultrapure water machine is much higher than that of traditional pure water production equipment, and has become one of the laboratory water production equipment in various water industries. 

Generally speaking, the higher the purity of the laboratory water, the more difficult it is to store for too long, in the case of 18.2MΩ.cm ultrapure water, the longer it is placed, the more serious the decline, under normal circumstances, the resistivity of ultrapure water placed for 1 hour will drop to 4MΩ.cm, and the pH will drop to about 5.7, and at the same time, due to the influence of the environment, the microorganisms in the water will breed rapidly.

Therefore, under normal circumstances, ultrapure water should not be stored for a long time after being extracted, and the concept of ready-to-use use should be followed. At the same time, in order to ensure the quality of pure water and ultrapure water, we should pay attention to the following points when taking water:

 1. The ultrapure water machine should be flushed once every 7-10 days to prevent the growth of bacteria.
 2. In the case of long-term inapplicability, it is necessary to drain all the water in the water purifier and water tank
 3. When the ultrapure water machine takes water, the initial pure water and ultrapure water should be discharged, and the water should be taken after the water quality is stable.
 4. Do not place the water purifier and water storage tank in direct sunlight to prevent the growth of bacteria. 

The above is the time that the ultrapure water mechanism can store the water after taking it, and the user needs to have a certain understanding of it in order to better use the equipment and not waste the pure water produced

2. How to reduce the growth of microorganisms in the ultrapure water machine?

How can I reduce microbial growth in my ultrapure water machine? After the ultrapure water machine is used for a long time, due to the sealing environment, with the growth of the use time, the pure water and ultrapure water taken by the final ultrapure water machine exceed the standard, is there any way to reduce the microbial breeding of the ultrapure water machine? Today, the editor of the seepage source water purifier brings you how to reduce the growth of microorganisms in the ultrapure water machine.

The methods of microbial breeding in ultrapure water machines generally have the following reasons:

1. Water seepage occurs due to poor contact in the sealed environment, which eventually leads to the internal environment being affected by external microorganisms and breeding bacteria.
2. The consumables have not been replaced for a long time, resulting in excessive accumulation of microorganisms on the reverse osmosis membrane, and eventually the increase of microorganisms and the decline of water quality.
3. The ultrapure water machine has not been used for a long time, and the microorganisms have grown in the state of placement.
4. The inlet water quality is poor, which leads to the rapid consumption of consumables in the pretreatment system, and ultimately leads to the rapid reproduction of microorganisms.

There are several ways to reduce microbial growth in ultrapure water machines：

1. Always ensure the regular start-up cycle of the ultra-pure water machine, so that the pipeline can enter the flow circulation.
2. Replace consumables regularly, check the water quality regularly, and replace them in time when the water quality is unqualified, which can effectively reduce the growth of microorganisms.

3. The way to maintain the water quality of the ultrapure water machine.

The quality of the water removed by the water purifier is not only based on the pure water equipment, but also depends on how to operate it correctly in the daily use process to maintain the water quality of ultrapure water. Here's how to maintain the quality of ultrapure water.

1. The water storage tank of the ultrapure water machine should be equipped with an air filter to prevent air from penetrating into the water storage barrel through the water intake and causing water pollution.
2. Since ultrapure water is easily polluted by environmental factors after taking water, it is best to use it when it is needed to minimize the contact between ultrapure water and the environment.
3. The water storage bucket of the ultrapure water machine should be avoided in direct sunlight as much as possible.
4. Ultrapure water stored in water storage barrels for a long time should be avoided as much as possible to prevent the water quality from deteriorating due to long-term storage.
5. When using ultrapure water, the initial ultrapure water should be discharged before using a water intake vessel.
6. When the water purifier is not used for a long time, all the pure water in the pressure storage bucket should be discharged to prevent pollution.
7. The water purifier needs to be watered once a week to prevent bacteria from being contaminated.
8. When taking water, try to avoid blisters and affect the water quality.
