Document Type and Number:
WIPO Patent Application WO/2019/172359
Kind Code:
A1
Abstract:
Provided are a dissolved matter removal device, a filtration aid used therewith, and a dissolved matter removal method with which it is possible to more efficiently remove hard-to-remove dissolved matter. As such, this dissolved matter removal device 1 comprises a spring-shaped filter 2 and a filtration aid 3 disposed around the spring-shaped filter 2. The filtration aid 3 contains a polymeric material comprising a graft chain to which is bonded a chelate group and/or an ion exchange group.
