Title:
METHOD OF DESALTING, APPARATUS FOR DESALTING, AND BUBBLE GENERATOR
Document Type and Number:
WIPO Patent Application WO/2008/053700
Kind Code:
A1
Abstract:
A method of desalting which comprises generating fine bubbles in a raw water containing a
salt and subjecting the raw water containing the fine bubbles to filter membrane separation.
By the method, even when an operating pressure to be applied on the raw-water
side is low, a sufficient effective pressure acts on the filter membrane to enable
the water to be efficiently filtered. Even with an operating pressure on almost
the same level as conventional ones, treated water can be obtained in a larger
amount. Also provided is a desalting apparatus which comprises a storage means
(1), a supply means (2), and a bubble generator (8) which generates fine bubbles
in a raw water to be fed through a pressurizing means (3), and in which the raw water
containing the fine bubbles is separated with a filter membrane by means of a separation
means (4) disposed downstream from the bubble generator (8).
