Reasons why the cartridges of RO security filters often collapse
Thread Content
Because Ro replaced the new filter element last September. Recently, for some unknown reason, the water volume discharged by the RO system over a 24-hour period has been gradually decreasing – it started at 100 units and dropped to just over 20 units by the end. After removing the safety filter, it was found that its filter element was collapsed; after replacing the filter element, the same problem reoccurred after another 24 hours. The turbidity of the water entering the RO system is 0.62, while the turbidity of the water exiting the activated carbon filtration tank at the front end is between 0.6 and 0.8. The filter element uses a 5um filter element. Could an expert please analyze what the exact reason is?
I. It may be due to quality issues with the filter elements (the quality of filter elements from different batches produced by the same manufacturer can also vary)； II. The filter element is clogged, caused by negative pressure (is the water quality the same as it was before?) ； III. Whether the front-end filter (activated carbon) has failed. The reasons should be sought in two aspects: water quality and the quality of the filter elements
Where are the pressure fluctuations large?
Did you not pay attention to the changes in the pressure difference gauge? Did the equipment stay shut down for some time, during which the water inside the equipment or in the pipes was not drained? As a result, after the device is turned on, there are many impurities and bacteria in the water, which causes the filter elements to get clogged very quickly.
