Title:
TEMPERATURE-SENSITIVE ABSORBENT, WATER TREATMENT METHOD, AND WATER TREATMENT APPARATUS
Document Type and Number:
WIPO Patent Application WO/2015/156404
Kind Code:
A1
Abstract:
This temperature-sensitive absorbent is employed as an attractant in the manufacture of fresh water by a forward osmosis process, the temperature-sensitive absorbent having a cloud point, and being designed to agglomerate when heated. This temperature-sensitive absorbent includes at least a hydrophobic portion and a hydrophilic portion, and is a block copolymer that has a glycerol skeleton as the basic skeleton thereof, and that includes an ethylene oxide group and a group comprising propylene oxide and/or butylene oxide. Alternatively, the temperature-sensitive absorbent is a block copolymer that has a trimethylolpropane skeleton as the basic skeleton thereof, and that includes ethylene oxide and butylene oxide.
