       The laboratory ultrapure water device needs to be regularly maintained and cleaned to ensure its long-term stable operation. If the filter column in the laboratory ultrapure water device is used and maintained improperly, it is easy to be damaged, so it must be Follow the correct method to prolong the life of the equipment.

And its precision filter element, activated carbon filter element, reverse osmosis membrane, and purification column are all materials with relative longevity. The precision filter element and activated carbon filter element are actually the protection of the reverse osmosis membrane. If they fail, the load of the reverse osmosis membrane will increase. The lifespan is shortened. If the machine continues to be turned on, the quality of the pure water produced will decline, which will increase the burden on the purification column, and the lifespan of the purification column will be shortened. The result is an increase in the cost of using the ultrapure water machine. In addition, maintenance and maintenance after using the laboratory ultrapure water device for a long time is also very important. Let's talk about it in detail.

1. First, clean the membrane elements in the reverse osmosis system;

2. Use the water produced by reverse osmosis to prepare bactericidal liquid, and use the bactericidal liquid to flush the reverse osmosis system;

3. After filling the reverse osmosis system with sterilizing liquid, close the relevant valves to keep the sterilizing liquid in the system. At this time, it should be confirmed that the system is completely full;

4. If the system temperature is lower than 27℃, the first two steps should be performed with a new sterilization solution every other month. If the system temperature is higher than 27℃, the sterilization solution should be replaced every two weeks;

5. Before the single-stage reverse osmosis pure water machine system is put into use again, flush the system with low-pressure feed water for one hour, and then flush the system with high-pressure feed water for 5 minutes. Regardless of low-pressure flushing or high-pressure flushing, the system's product water discharge valve should be flushed. All open. Before resuming normal operation of the system, check to make sure that the water in the product does not contain any biocides.

The above is the maintenance and maintenance method of the laboratory ultrapure water device. Before using it, you need to have a certain understanding of the equipment, so that you can use the equipment better.
