1 Damage to membrane performance caused by untimely cleaning and incorrect cleaning method

In addition to the normal attenuation of equipment performance, the attenuation of equipment performance caused by pollution is more serious during the use of equipment. Common pollution mainly includes chemical scale, organic matter and colloid pollution, microbial pollution, etc. Different pollution shows different symptoms. The symptoms of membrane pollution proposed by different membrane companies are also different.

In the project, we found that the duration of pollution is different, and the symptoms are also different. For example, the membrane is polluted by calcium carbonate scale. When the pollution time is one week, it mainly shows that the desalination rate drops rapidly, the pressure difference increases slowly, and the water yield changes little. Washing with citric acid can completely restore the performance. The pollution time is one year (a water purifier), the salt flux increases from the initial 2mg/L to 37mg/L (raw water is 140mg/L~160mg/L), and the water yield decreases from 230L/h to 50L/h. After cleaning with citric acid, the salt flux decreases to 7mg/L, and the water yield increases to 210L/h.

Moreover, pollution is often not single, and its symptoms are also different, making it more difficult to identify pollution.
