The Aquarius system from<br />
Hamworthy and Hanovia employs<br />
filtration followed by disinfection<br />
using ultraviolet light<br />

The Aquarius-UV system follows a twostage<br />
process with filtration followed by<br />
disinfection using ultraviolet light, and so<br />
does not use any active substance. Because<br />
<strong>the</strong>re is no detrimental effect on water<br />
quality, ballast water can be safely discharged<br />
from <strong>the</strong> ballast tank at any time. In addition,<br />
to ensure maximum disinfection, ultraviolet<br />
treatment is utilised during <strong>the</strong> discharge<br />
cycle, as well as during ballasting.<br />
In developing <strong>the</strong> Aquarius-UV system,<br />
Hamworthy has formed a strategic partnership<br />
with UK-based Hanovia, a specialist in<br />
UV system design and manufacturing.<br />
Hamworthy has assumed overall responsibility<br />
for performance compliance against <strong>the</strong><br />
required regulatory standards, with <strong>the</strong> UV<br />
system being an essential component to<br />
integrate with Hamworthy’s ballast water<br />
management solution.<br />
Hamworthy is also marketing its<br />
Aquarius-EC <strong>Ballast</strong> <strong>Water</strong> System, which<br />
similarly employs a two-stage approach,<br />
but in this case disinfection uses an active<br />
substance, generated using side-stream<br />
electro-chlorination.<br />
