Application
When ships take on ballast, they take on more than water.
Microscopic organisms, eggs, cysts and even the planktonic
larvae of larger organisms are small enough to pass through
the intakes and pumps.
If these organisms survive transport to other parts of the
globe, their impact can be devastating. In seas that are weakened
by overfishing and pollution, non-native species can
reproduce quickly and deprive local species of food and living
space. Such invasions can jeopardize local economies and
even human health, and their effects are usually irreversible.
IMO has identified the introduction of species via ballast
water as one of the four greatest threats to the world’s
oceans. In 2004, the organization adopted the International
Convention for the Control and Management of Ships’ Ballast
Water and Sediments, which will phase in requirements for
ballast water treatment over the coming years.
PureBallast from Alfa Laval
PureBallast is an easy-to-use ballast water treatment system
that meets the new IMO requirements. Unlike many proposed
systems, which rely on chemicals or are too large to
implement in real life, PureBallast involves no environmental
or operational compromises.
Using a unique, chemical-free technology, PureBallast produces
radicals that neutralize organisms in ballast water. The
process is effective, automated and self-contained, as well
as harmless to the ballast tanks and crew. PureBallast is the
first ballast water treatment system without chemicals to
have received full Ballast Water Type Approval, having consistently
demonstrated the necessary biological efficiency in
land-based and onboard trials.
Since PureBallast is also remarkably compact, it can be
installed even in cramped engine room conditions or in areas
that are otherwise difficult to utilize. By combining spacesaving
design, chemical-free technology and full automation,
PureBallast is the clear choice for both installation and
operation.
