How to analyze the abnormal operation data of purified water equipment?

After the purified water equipment is officially put into use, it is necessary to make operation records Through these operation records, you can master the operation status of the purified water equipment Once the data changes, you must do an effective analysis to determine the source of the fault Now let's understand how to analyze the abnormal operation data of purified water equipment First, the cause analysis of low water production resistivity When the water production resistivity becomes low, we can analyze and consider from the following three aspects 1 Analyze the average current between each module, the actual current between them, the pressure value change of the concentrated fresh water chamber, and the operation data records in the near period of time to analyze the reasons 2 It can analyze the testing instrument: testing instrument to see if the data is inaccurate due to the instrument problem 3 Analyze the influent parameters from the aspect of influent water quality, and test the raw water quality to see if the influent index changes 2 The reason why the conductivity of the produced water is higher than that of the inlet water When this happens, the purified water equipment shall be stopped immediately and the reason shall be checked to see whether it is caused by the following points: 1 Whether there is reverse electrode of the module 2 Whether the concentrated water chamber enters the fresh water chamber in reverse direction 3 Whether the pressure of concentrated water chamber is greater than that of fresh water chamber III If the current increases, the water quality will decrease Check whether the ultra pure water equipment has membrane failure or damage The above situations are common data abnormalities during the long-term operation of purified water equipment You can use the above contents as reference materials to understand the source of the problem and corresponding solutions.
