Document Type and Number:
WIPO Patent Application WO/2015/005186
Kind Code:
A1
Abstract:
A water treatment method provided with an anaerobic treatment step for anaerobically treating water to be treated containing organic matter is characterized by being further provided with a concentration step for concentrating the water to be treated before the anaerobic treatment by bringing a draw solution formed to produce osmotic pressure by penetration of moisture from the water to be treated through a semipermeable membrane and the water to be processed into contact with each other with the semipermeable membrane therebetween, and supplying the water to be treated after the concentration step to the anaerobic treatment step to perform the anaerobic treatment.
