Provided is a system preventing or reducing adhesion of a raw material component to a membrane surface and increasing the recovery rate of the raw material component after concentration. A raw material liquid concentration system for a medicine production process comprising a forward osmosis membrane unit having a forward osmosis membrane, and a raw material liquid side space and an inductive solution side space which are separated from each other by the forward osmosis membrane; a raw material liquid channel supplying, to the raw material liquid side space, a raw material liquid containing a solvent and a solute; an inductive solution channel supplying, to the inductive solution side space, an inductive solution containing an inductive material; a concentrated liquid channel removing a concentrated raw material liquid from the forward osmosis membrane unit; and a diluted inductive solution channel removing a diluted inductive solution from the forward osmosis membrane unit.

Raw material liquid concentration system

[PROBLEM] To provide an evaluation method and evaluation device with which the practical performance of a forward osmosis membrane can more accurately be measured. [SOLVING MEANS] Provided is a method for evaluating a forward osmosis membrane module. The method includes the steps of, in a forward osmosis membrane module having spaces which are partitioned by a forward osmosis membrane including a porous support body and a separation function layer stacked thereon, connecting a feed solution line to a space on the separation function layer side, and connecting a draw solution line to a space on the porous support body side, and moving a solvent in the feed solution into the draw solution via the forward osmosis membrane while adjusting a physical pressure differential across the forward osmosis membrane to a constant value within the range of more than 0 kPa to 200 kPa.

Evaluation method and evaluation device for forward osmosis membrane module

Provided are a forward osmosis membrane, a forward osmosis membrane module, and a manufacturing method thereof, wherein a forward osmosis membrane, which achieves an extremely favorable reduction in the reverse diffusion of salt compared to the prior art and has a predetermined water permeability, is developed thereby bringing about: practicality in that a liquid-like raw material solution used in actual concentration operations can be concentrated with suppressed diffusion of an induction solution even when used multiple times; and durability in that the performance of the membrane can be maintained within a predetermined range even when a raw material solution having an osmotic pressure is concentrated multiple times.

Forward osmosis membrane, forward osmosis membrane module, and manufacturing method thereof

An aircraft tire management system includes a management device capable of communicating with a tire manufacturer, an MRO-providing company, and an airline through a network, and an acquisition device configured to acquire tire individual information on aircraft tires and wheel individual information on wheels. The acquisition device sends the tire individual information acquired in the tire manufacturer to the management device, sends the tire individual information and the wheel individual information on each aircraft tire fitted on the corresponding wheel acquired in the MRO-providing company to the management device, and sends the wheel individual information acquired in the airline to the management device. The management device links the tire individual information with the wheel individual information, and outputs tire management information including at least tire identification information, location information, and date and time information.
