PREPARATION METHOD OF ULTRAFILTRATION MEMBRANE, WATER TREATMENT METHOD, AND ULTRAFILTRATION MEMBRANE DEVICE

摘要

To provide a preparation method of an ultrafiltration membrane where high performance and high reliability of the ultrafiltration membrane can be achieved by a simple method, and to provide an ultrafiltration membrane device which has the ultrafiltration membrane prepared by such the preparation method, which has high performance and high reliability and which can suppress costs.SOLUTION: Performance of an ultrafiltration membrane for removing particles is improved by treatment adding fine particles to the ultrafiltration membrane after passing through preparative water containing the fine particles to the ultrafiltration membrane.SELECTED DRAWING: Figure 1
