Industrial Water Purifier System RO Water Filter 4040 Nano Membrane

With the increasing biofouling problem of reverse osmosis membranes, the research and development and application of anti-biofouling membranes have become a focus of attention. At present, the evaluation methods of antibacterial properties of membranes are static evaluations of the antibacterial properties of the membrane surface, while dynamic testing methods are closer to The actual use conditions, the characterization of the microstructure of the reverse osmosis membrane before and after fouling can further understand the fouling mechanism of biological fouling. Taking Escherichia coli as the biological fouling model, the membrane permeability degradation and microstructure changes caused by biological fouling were studied by dynamic experiments. Results It is shown that the biofilm formed on the surface of the reverse osmosis membrane causes the water flux to rapidly decay by more than 50%; the results of scanning electron microscopy show that the membrane surface has been completely covered by biofilm; the results of fluorescence microscopy show that there are both live and dead bacteria in the biofilm on the membrane surface; The biofouling of the membrane leads to a decrease in the hydrophilicity of the membrane surface, an increase in the potential, and an increase in the roughness. A new absorption peak appears at 1734.68 cm-1 in the infrared spectrum, indicating that proteins and esters exist on the surface of the reverse osmosis membrane. The biofilm will separate Biofouling is a type of pollution that has a great impact on the overall performance of the membrane, and it is particularly important to prevent biofouling.
