Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a deoxygenation treatment device capable of removing dissolved oxygen in water being treated with sufficiently high efficiency.SOLUTION: A deoxygenation treatment device 100 according to the present invention comprises: a filtration part 10 having a container whose inner space is divided in a primary side area and a secondary side area by a filtration membrane, making treatment object water flow in from the primary side, making filtration water flow out from the secondary side, and making a part of the treatment object water flow out from the primary side; a filtration water line 30; a circulation line 20; a deaerator 31 which is connected to the filtration water line 30 and whose inside space is divided in a primary side area and a secondary side area by a deaeration membrane; a decompression device 21 connected to the circulation line 20; and a deaeration line 50 connecting the deaerator 31 and the decompression device 21 in communication. The decompression device 21 makes a pressure of the secondary side area of the deaerator 31 lower than a pressure of the primary side area of the deaerator 31 by using a water flow in the circulation line 20.SELECTED DRAWING: Figure 1
