METHOD FOR FILTRATION BY HOLLOW FIBER MEMBRANE MODULE

摘要

PROBLEM TO BE SOLVED: To provide a method for filtration by a hollow fiber membrane module in which the cleaning of membrane surfaces is easy and which is particularly suitable for filtering a liquid of high turbidity due to organic substances. SOLUTION: In the filtration method, the hollow fiber membrane module in which one end part or both end parts of the hollow fiber membrane formed in the shape of a sheet are fixed by a fixing member in a housing while the hollow fiber membrane is opened is used, and the module is arranged so that the longitudinal direction of the hollow fiber membrane of the module is perpendicular.
