| Abstract: | The ultrafiltration membrane fouling and the main methods to alleviate membrane fouling were summarized.The causes,main pollutants and types of pollution were introduced.The main methods of membrane pretreatment,membrane cleaning and membrane modification and the new methods of membrane fouling control such as ultraviolet,applied magnetic field and electric field were introduced.The research direction of controlling membrane fouling from the source was summarized.It is believed that ultrafiltration technology requires more appropriate choices in operation mode and process design,and it will develop in the direction of low energy consumption,low drug consumption,automation and greening in the future. |
