Cross-flow filtration method and cross-flow filtration device |
| abstract |
A method of cross-flow filtration using a membrane filter has a feeding a fluid to be filtered across a membrane surface of a porous alumina membrane filter serving as the membrane filter so that the fluid flows parallel to the membrane surface to separate material to be filtered with the porous alumina membrane filter. The porous alumina membrane filter is made of an aluminum anodized film and includes micropores having a degree of ordering as defined by formula (1): Degree of ordering (%)=B/A×100 (1) of at least 50%, a porosity as defined by formula (2): Porosity (%)=C/D×100 (2) of at least 40%, and a percentage of a pore size standard deviation to an average pore size of up to 10%. |
