Ultrafiltration membrane can remove colloid, virus and large molecules of organic matter, but it does not have the ability to remove small molecules of organic matter and ionic pollutants, and the nanofiltration membrane can effectively remove organic matter and inorganic salts and other pollutants. However, the research and application of nanofiltration advanced water treatment technology are still few in China. In this experiment, ultrafiltration membrane was combined with nanofiltration membrane to make a rapid detection instrument. The instrument was used to test key performance indicators such as desalination rate and water flux under different pressures, which proved that the instrument could quickly detect related indicators of the membrane and its efficiency could be doubled.
