Document Type and Number:
WIPO Patent Application WO/2021/131345
Kind Code:
A1
Abstract:
Provided is a water treatment device equipped with a filtration device that removes iron, with lower capacity and reduced heat loss. The present invention comprises: a filtration device (22) that removes iron from the condensate led from a condenser (20) and also removes iron from the drain water led from a low-pressure feedwater heater (44); and a switching means for selectively switching between the flow of condensate from the condenser (20) to the filtration device (22) and the flow of drain water from the low-pressure feedwater heater (44) to the filtration device (22). The capacity of the filtration device (22) is determined on the basis of the maximum value of the required filtration flow rate of the condensate.
