High Tds Ro Membrane 80 Gpd TW-1812-75 GPD Flow RoHS NSF

TW-1812-75G Domestic RO Membrane for RO Water Purifier Parts

During the use of the equipment, in addition to the normal performance degradation, the performance degradation of the equipment due to pollution is more serious. The usual pollution mainly includes chemical scale, organic matter and colloid pollution, and microbial pollution. Different types of pollution show different symptoms. There are also some differences in the symptoms of membrane fouling proposed by different membrane companies. In the project, we found that the length of the pollution time is not the same, the symptoms are not the same. For example, the membrane is polluted by calcium carbonate scale. When the pollution time is one week, the main performance is that the desalination rate drops rapidly, the pressure difference increases slowly, and the change of water production is not obvious. Cleaning 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 production decreases from 230L/h to 50L/h, After washing with citric acid, the salt flux decreased to 7 mg/L and the water production increased to 210 L/h.
