Abstract: A water quality management method for performing at least one of a quantitative analysis and a qualitative analysis of fine particles contained in water to be analyzed that includes connecting a filtration device provided with a fine particle capturing membrane for capturing fine particles to a flow pipe through which the water to be analyzed flows, allowing the water to be analyzed to flow from the flow pipe and through the fine particle capturing membrane attached to the filtration device for a predetermined period of time to capture fine particles contained in the water to be analyzed to form a fine particle capturing membrane sample, and performing at least one of a quantitative analysis and a qualitative analysis of the fine particle capturing membrane sample of a target water flow period at an arbitrary timing.

Abstract: A centrifugal filtration device is provided. The centrifugal filtration device has filtration membrane that filtrates liquid; cartridge that supports filtration membrane and that forms liquid chamber together with filtration membrane, wherein liquid chamber holds the liquid therein; and rotating member that rotates around rotation center and that supports cartridge such that filtration membrane is positioned outward of liquid chamber with respect to rotation center. Rotating member has a path that is connected to liquid chamber, and at least a part of a liquid contact part of the path that is in contact with the liquid is formed of titanium or a titanium alloy.

Abstract: An ultrapure water production apparatus (1) includes an ultrafiltration membrane device (10). The ultrafiltration membrane device (10) includes a plurality of ultrafiltration membranes (11, 12) that are connected in series. The plurality of ultrafiltration membranes (11, 12) include a first ultrafiltration membrane (11) and a second ultrafiltration membrane (12) located farthest downstream among the plurality of ultrafiltration membranes (11, 12), the second ultrafiltration membrane (12) having filtration properties that are different from filtration properties of the first ultrafiltration membrane (11).
