How to judge whether the filter element of ultrapure water machine needs to be replaced

       Ultrapure water machines have a certain service life, and the actual service life is affected by many factors, such as raw water quality, frequency of use, usage habits and so on. So in the process of use, how should we judge that the filter element needs to be replaced? Let's talk about it in detail.

1. The amount of water in the ultrapure water mechanism becomes smaller

Under the condition that the water temperature and water pressure have not changed, the water production volume becomes smaller, then it is likely that the filter element is blocked. At this time, we can try to clean the filter element. If the filter element is still small after cleaning and cannot meet the needs, the filter element may reach its At this time, we need to replace the new filter element for the ultrapure water machine.

Second, the ultrapure water mechanism is too fast

If the water purifier appears to speed up the production of water, it is considered that the reverse osmosis membrane is damaged and the filtration function is lost. At this time, we need to consider replacing the RO reverse osmosis membrane.

3. Water quality is not up to standard

If the water quality continues to fail to meet the standard under other conditions without abnormality, you should consider replacing the filter element.

4. Arrival Theoretical Time Value

Under normal circumstances, except for areas with serious water pollution, the consumables of ultrapure water machines have a replacement cycle. The following suggestions are made for the replacement time of consumables:

1. Pretreatment: It mainly filters out rust, sediment, fibers and other impurities that can be considered, and reduces residual chlorine, heavy metals, different colors and odors in the water and some organic substances. The recommended replacement cycle is 3-6 months.

2. Reverse osmosis column: effectively intercept bacteria, heavy metal organic matter, etc. in water; impurity removal rate can reach 95-99%, and the recommended replacement cycle is 18-24 months.

3. Ultra-purification column: further purify water quality and produce ultra-pure water that meets laboratory requirements. It is recommended to replace it after it can produce 1.0 tons of ultrapure water under the inlet water of 15μs/cm.

When using the ultra-pure water machine, pay attention to the replacement of the filter element, so as to maintain good water and water quality, and also ensure the working life of the equipment.

The above are the main points for judging whether the filter element of the ultrapure water machine needs to be replaced. I hope it can help everyone to use the ultrapure water machine better.
