Abstract: After absorbing oxygen together with carbon dioxide in an absorber 103, absorbing liquid 104a is supplied to oxygen collecting units 13 and 14. The oxygen collecting units 13 and 14 include silver to collect the oxygen in the absorbing liquid 104a and eliminate the oxygen from the absorbing liquid 104a. A regenerating unit 15 separates and recovers the oxygen collected in one of the two oxygen collecting units 13 and 14 to regenerate the oxygen collecting unit when the other oxygen collecting unit is supplied with the absorbing liquid 104a. A continuous operation can be achieved by switching and using the two oxygen collecting units 13 and 14.

Abstract: Provided is a membrane filtration system which makes it possible to improve operation rate of the system by increasing the amount of water to be treated, and to reduce costs required for chemical washing and replacement of a membrane. Accordingly, a total running cost is reduced. The membrane filtration system is provided with temperature-responsive membrane modules for filtering supplied raw water to discharge it as treated water. In each of the temperature-responsive membrane modules, temperature-responsive membranes are formed into any one of planar and cylindrical forms, and are then filled into a container.
