Title:
WATER TREATMENT DEVICE FOR BOILER FEED WATER AND METHOD FOR OPERATING BOILER
Document Type and Number:
WIPO Patent Application WO/2017/064962
Kind Code:
A1
Abstract:
Provided is a water treatment device for boiler feed water that can efficiently eliminate hard components and other impurities in raw water while suppressing energy consumption and increase boiler concentration rate. An RO membrane device 1 and water softener 2 are disposed in parallel and treated water is obtained by treating raw water with the RO membrane device 1 and/or the water softener 2; the treated water obtained is used as a boiler feed water. Thus, by the RO membrane 1 and water softener 2 being disposed in parallel, each performing processing, and the treated water from each being mixed, it is possible to obtain treated water that is cleaner than conventional treatment by water softener alone, thereby increasing the concentration rate of the boiler. By performing processing in parallel, it is possible to make each device smaller, thereby suppressing the energy consumed and the amount of waste water to a low level.
