【Abstract】 The common cleaning process and cleaning agents were used to clean the hollow fiber ultrafiltration membranes fouled by tannic acid and pectin,which were regarded as the main pollutants in the decocta of traditional Chinese herbs.The results showed that the flus was recovered well after the cleaning using several chemical agents alternately combined with physical methods,and the good repeatability was observed.
