Title:
MEMBRANE FILTRATION APPARATUS, CONCENTRATION APPARATUS, AND CONCENTRATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/201866
Kind Code:
A1
Abstract:
A membrane filtration apparatus 110 is provided with a membrane 113, in which the membrane 113 is made from an acid-resistant material, has pores each having such a pore diameter that microorganisms can be trapped in the pore, and has a surface that can be negatively charged in a neutral to alkaline region.
