Title:
SHIP BALLAST WATER TREATMENT SYSTEM
Document Type and Number:
WIPO Patent Application WO/2012/061924
Kind Code:
A8
Abstract:
There is described a fluid treatment system that is particularly well suited for treating ballast water on a shipping vessel. The present fluid treatment system is characterized by having two general modes of operation. A so-called ballasting mode and a so-called deballasting mode. In the ballasting mode, water is pumped from the sea or other body of water in which the shipping vessel is located to a ballast fluid inlet in the present fluid treatment system. Thereafter, it passes through the filter separation and radiation treatment sections in the fluid treatment zone of the fluid treatment system. Next, the fluid exits the fluid outlet of the fluid treatment system and it is pumped to one or more ballast tanks that are located on the shipping vessel. In the deballasting mode, water contained in the ballast tank(s) is pumped to a deballasting fluid inlet of the fluid treatment system after which it is treated in the radiation section only - i.e., in the deballasting mode, water substantially bypasses the fluid separation section of the fluid treatment system. Next, the treated fluid exits the fluid outlet of the fluid treatment system and is discharged overboard the shipping vessel. A valve system is used to switch between ballasting mode and deballasting mode.
