When does the filter element of ultra pure water machine need to be replaced?

The filter element of ultra pure water machine belongs to consumables and has a certain service life The actual service life is affected by many factors, such as raw water quality, use frequency, use habits and so on In the process of using, how should we judge that the filter element needs to be replaced? 1 When the water volume of ultra pure water mechanism is smaller and the water temperature and water pressure are not changed, the water volume is smaller, so 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 too small to meet the needs after cleaning, it is likely that the filter element has reached its service life At this time, we need to replace the ultra pure water machine with a new filter element II If the ultra pure water mechanism water is too fast and the water produced by the water purifier is obviously accelerated, 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 III If the water quality is not up to standard and the water quality is not up to standard continuously in other cases without abnormality, the filter element shall be replaced IV under normal conditions, except for the areas with serious water pollution, the consumables of ultra pure water machine have a replacement cycle The following suggestions are made by EUP on the replacement time of consumables: 1 Pretreatment: mainly filter the filterable impurities such as rust, sediment and fiber, reduce the residual chlorine, heavy metal, heterochromatic odor and some organic matters in the water, and the recommended replacement period is 3-6 months 2 Reverse osmosis column: it can effectively intercept bacteria and heavy metal organics in the water; the removal rate of impurities can reach 95-99%, and the recommended replacement period is 18-24 months 3 Ultra purification column: further purify the water quality to produce ultra pure water meeting the requirements of the laboratory It is suggested to replace it after 1.0T ultra pure water can be produced under 15 μ s / cm of influent water When using ultra pure water machine, pay attention to the replacement of filter element, so as to maintain good water quality and water quality, and also ensure the working life of the equipment.
