| titleOfInvention | Operation method of hollow fiber membrane module |
| abstract | The present invention provides a method for operating a hollow fiber membrane module that enables efficient cleaning while reducing abrasion on the membrane surface due to air cleaning. A unit process including a filtration step of supplying raw water of solid-liquid mixing to a hollow fiber membrane module and filtering, and a washing step of removing the adhering matter of the hollow fiber membrane after the filtration is stopped Is a method of operating a hollow fiber membrane that is configured as one or a plurality of groups, and the configured group is repeatedly executed, and the amount of air that has passed through the hollow fiber membrane during a single unit cleaning step Is the cleaning step A, and the cleaning step A is a cleaning step having an air cleaning strength of 1.5 times or more the average value of the air cleaning strength of each cleaning step performed in the one group. The average value of the air cleaning strength is 2 to 50 times the average value of the air cleaning strength in the cleaning steps other than the air cleaning step A, and the ratio of the cleaning step A to the total number of cleaning steps included in the one group is Hollow characterized by 1-50% Method of operating a membrane module.
