Title:
BALLAST WATER TREATMENT METHOD USING BALLAST WATER TREATMENT MEMBRANE CARTRIDGES
Document Type and Number:
WIPO Patent Application WO/2011/040603
Kind Code:
A1
Abstract:
Provided is a ballast water treatment method that uses ballast water treatment membrane cartridges, which enable the supply of a large amount of ballast-treated water to a ballast tank in a short amount of time. The ballast water treatment method uses ballast water treatment membrane cartridges which supply raw ballast water (10) to the membrane cartridges (1) having spiral membrane modules, and which alternate between filter processing to obtain treated water, and cleaning the membrane. During filter processing, a dead-end system is used to filter the entire volume of ballast water to obtain filter processed water. This is followed by membrane cleaning, during which the membrane surface is cleaned by having raw ballast water flow parallel to the membrane surface.
