Embodiment Construction

[0110] figure 1The arrangement uses electrodialysis units in ballast water treatment systems, but recognizes that there are other applications where electrodialysis units are preferred and that electrodialysis units can be tailored to suit different requirements. In particular, it should be understood that the electrodialysis unit described herein may be used for ballast water treatment, or for other water treatment applications, without the need for a combination figure 1 Other treatment types shown in exemplary arrangements.

[0111] therefore, figure 1 A ballast water treatment system comprising an electrodialysis unit 8 is illustrated. In this example, the water is filtered and then treated through the cavitation unit 10 , the gas injection unit 14 and the electrodialysis unit 8 . This series of treatments destroys and kills organisms in the water. As well as affecting organisms in the water, the nitrogen added to the water at the injection device 14 reduces the dissol...

Abstract

An electrodialysis unit 8 for treating water comprising: a membrane cell, a temperature monitoring device 9a for monitoring the temperature of the incoming water and a heater 9b for increasing the temperature of the incoming water before it reaches the membrane cell; wherein the heater 9b is arranged The temperature of the incoming water is increased for operation when the initial water temperature is below a predetermined level.

Description

technical field [0001] The present invention relates to the treatment of water by electrodialysis, such as treatment to kill microorganisms, preferably sea water, such as ballast water treatment. Background technique [0002] Ballast water is water carried by a ship in ballast tanks or sometimes in other suitable spaces such as cargo or oil tanks. It is pumped into the tank at the water "donor" location to compensate for changes in the center of gravity as cargo and / or fuel is unloaded / consumed, and thus maintain stability. Proper ballasting is essential from a structural point of view and also for performance reasons in order to ensure proper propeller and rudder immersion, proper bridge considerations and to maintain desired vessel movement and handling characteristics. Ballast water is transported to a water "holding" location, typically where the vessel is loaded with cargo, potentially outside the biogeographical region of the ballast water source. Ballast water can b...
