How to know if the filter element of ultrapure water machine needs to be replaced

When using the ultra pure water machine, pay attention to the replacement of the filter element, which can maintain good flow out water and water quality, and also ensure the working life of the equipment. So how to know if the filter element of the ultra pure water machine needs to be replaced?

Judging that the filter element of ultrapure water machine needs to be replaced can be found through four daily behaviors:

1.The water volume of ultra pure water machine becomes smaller

If the water volume of your ultrapure water machine becomes smaller when the water temperature and pressure are stable, it is likely that the filter element of the ultrapure water machine is polluted and blocked. Try to clean the pollution of the filter element first. If the problem of small water output still occurs after cleaning, it indicates that the filter element and its service life have been reached. At this time, the filter element of the ultrapure water machine needs to be replaced.

2.Ultrapure water produced is too fast

When the ultrapure water machine is used, the water making speed becomes faster and the water making time becomes shorter, which indicates that the water making time of the ultrapure water machine becomes shorter. At this time, we need to consider replacing the osmosis membrane and filter element. Whether the reverse osmosis membrane is damaged and loses the filtering function, and then we need to replace the RO reverse osmosis membrane.

3.Water quality not up to standard

Generally, the effluent quality after daily water preparation cannot meet the experimental demand standard. If the ultra pure water machine fails to meet the experimental standard continuously without other faults, contact the after-sales maintenance personnel to replace the filter element as soon as possible.

4.Service life theory

Generally, if the ultrapure water machine is not used in areas with serious water pollution, the consumables of the ultrapure water machine have a relatively stable service life.

1. Pretreatment column: it mainly filters out rust, sediment, fiber and other impurities, and reduces residual chlorine, heavy metals, heterochromatic odor and some organic matters in water. It is recommended to replace it for 3-6 months.

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

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

I believe that through the above understanding, you have the desired answer to the replacement of the filter element of the ultrapure water machine. Warm tips for pure water treatment: when using the ultrapure water machine, pay attention to the replacement of the filter element, which can not only maintain good effluent and water quality, but also greatly prolong the service life of the equipment.
